The best abandoned cart subject lines use urgency, personalization, and curiosity to recover lost sales. With cart abandonment rates at 70.19%, your subject line determines whether a recovery email gets opened or ignored. Below are 50+ proven examples grouped into 13 categories with real brand screenshots.

Why Do Abandoned Cart Subject Lines Matter?

Your subject line is the gatekeeper between a recovered sale and a permanently lost customer. According to Baymard Institute, the average documented online shopping cart abandonment rate is 70.19%. That means roughly seven out of every ten shoppers leave without buying.

The math here is straightforward. If your store generates $100,000 in monthly revenue, abandoned carts represent another $233,000 in potential sales walking out the door. Recovery emails with strong subject lines can claw back 10-15% of that lost revenue.

But here's the catch: your recovery email is competing with 100+ other messages in your customer's inbox. According to Klaviyo's abandoned cart benchmarks, abandoned cart flows drive the highest average revenue per recipient ($3.65) and the highest placed order rate (3.33%) of all email automation flows. The subject line is what unlocks that performance.

I've analyzed hundreds of abandoned cart emails while working in abandoned cart recovery strategies. The pattern is clear: brands that invest in testing multiple subject line approaches consistently outperform those that default to "You forgot something" on repeat.

What Makes a Great Abandoned Cart Subject Line?

I evaluated 200+ abandoned cart emails from e-commerce brands across fashion, tech, food, and DTC verticals and selected the examples below based on four criteria:

Open rate potential: Subject lines that use proven psychological triggers (curiosity gaps, loss aversion, personalization tokens) based on email marketing research and A/B test data from platforms like Klaviyo and Drip

Brand alignment: The subject line matches the sender's overall tone. A playful brand like Chubbies can say "Howdy bud" while a premium brand like Dyson needs something more reserved

Clarity of intent: The recipient understands within 30-50 characters (the mobile preview window) that this email is about their abandoned cart

Conversion evidence: Where possible, I prioritized examples from brands that have publicly shared performance data or that industry sources have cited as high-performers

Quick Overview of 13 Abandoned Cart Subject Line Categories

# Category Best For Example
1 Straightforward All audiences, safe default "Did You Forget This?"
2 Offer-Driven Price-sensitive shoppers "Take 10% Off Your Cart"
3 Curiosity Higher open rates "A Gift for You"
4 Suggestive Gentle reminders "Forgot something?"
5 Product-Related High-intent buyers "Still thinking about {product}?"
6 Friendly Casual brand voices "Howdy Bud?"
7 Customer Service Building trust "Can We Help?"
8 Brand Voice Established brands "Wanna Know a Secret?"
9 FOMO / Urgency Limited stock items "Your cart is about to expire"
10 Creative Standing out in inbox "Don't open this email"
11 Personalized Segmented lists "{Name}, Your Cart Needs You"
12 Emoji Younger demographics "Your cart misses you"
13 Emotional DTC and lifestyle brands "Your shopping bag has issues"

1. Straightforward Abandoned Cart Subject Lines

Kate Spade abandoned cart email with subject line Let's check this off your list
Kate Spade's direct approach to cart recovery

Straightforward subject lines skip the gimmicks and tell your customer exactly what the email is about. No wordplay, no discount tease, no mystery. Just a clear reminder that they left items in their cart.

This approach works because it respects the customer's time. In a crowded inbox, clarity wins. Kate Spade's "Let's check this off your list" is direct but still carries a subtle action cue.

Examples:

• "Did You Forget This?"

• "You Left Your {product name} Behind!"

• "Your Cart Is Waiting"

• "Complete Your Order"

Why it works: These subject lines front-load the intent. The recipient knows within two seconds this is about their cart. Kate Spade's version adds a productivity framing ("check this off your list") that makes completing the purchase feel like accomplishing a task rather than spending money.

According to Rejoiner's subject line analysis, the highest-converting abandoned cart subject line was "Your [Brand Name] Basket" with a 32.73% conversion rate. Straightforward subject lines outperform clever ones when the product intent is already high.

Key takeaway: If you're unsure where to start, go straightforward first. Test a simple reminder against your current subject line for two weeks before experimenting with other categories.

2. Offer-Driven Subject Lines

Chubbies abandoned cart email with subject line Lemme Teleport You Back Your Cart Free of Charge
Chubbies pairs humor with a free shipping offer

Offer-driven abandoned cart subject lines lead with a discount, free shipping, or bonus to pull price-sensitive shoppers back. Some customers abandon specifically because of cost, so putting the incentive right in the subject line removes their primary objection before they even open the email.

Examples:

• "Take 10% Off Your Cart Before It's Gone!"

• "Act Fast to Get 15% Off Your Cart!"

• "Free Shipping on Your Abandoned Cart"

• "Lemme Teleport You Back to Your Cart. Free of Charge." (Chubbies)

Why it works: Chubbies nails this by blending their playful brand voice with a concrete offer. "Free of Charge" is the hook, but the teleportation metaphor makes it memorable. The subject line is 56 characters, which fits within most mobile preview windows.

Shipping costs are the number one reason for cart abandonment. Addressing the objection directly in the subject line reduces the friction between seeing the email and clicking through. Dollar-based discounts tend to outperform percentage-based ones for higher-priced items, while percentage discounts work better for items under $50.

Key takeaway: Don't lead with an offer in your first cart recovery email. Save the discount for email two or three in your sequence so you don't train customers to abandon carts for discounts.

3. Curiosity-Piquing Subject Lines

Casper abandoned cart email with subject line Come Back To Bed
Casper's product-relevant curiosity hook

Curiosity subject lines create an information gap that the customer can only close by opening the email. They don't mention the cart directly. Instead, they hint at something interesting waiting inside.

Examples:

• "A Gift for You"

• "Olivia, Continue Shopping with a Discount"

• "Come Back to Bed" (Casper)

• "We Saved Something for You"

Why it works: Casper's "Come Back to Bed" is a masterclass in product-relevant curiosity. It works on two levels: as a cozy invitation and as a direct reference to their mattress product. The subject line is only 16 characters, which stands out in an inbox full of wordy competitors.

The curiosity gap triggers a psychological need for closure. George Loewenstein's information gap theory explains that people feel a mild discomfort when they detect a gap between what they know and what they want to know. Short, ambiguous subject lines amplify this effect.

Key takeaway: Keep curiosity subject lines under 30 characters. The shorter they are, the more the reader's brain fills in the gap, and the more compelled they feel to click.

4. Suggestive Reminder Subject Lines

Adidas abandoned cart email with subject line Sorry to hear about your WI-FI
Adidas assumes the best about why you left

Suggestive subject lines assume that the customer simply forgot or got distracted rather than deliberately choosing not to buy. This frames the abandonment as accidental, which feels less accusatory and more helpful.

Examples:

• "Forgot something?"

• "Olivia, You've Left Something Behind"

• "Sorry to Hear About Your Wi-Fi" (Adidas)

• "Looks Like You Got Interrupted"

Why it works: Adidas' "Sorry to Hear About Your Wi-Fi" is the standout here. It assumes the reason for abandonment was a technical glitch, not a change of heart. This removes any guilt from the customer and actually makes them smile. The subject line also shows brand personality without trying too hard.

Attribution theory in psychology shows that people respond more positively when negative outcomes are attributed to external causes (bad Wi-Fi) rather than internal ones (you changed your mind). By giving the customer an "excuse," Adidas makes it socially easier for them to come back and complete the purchase.

Key takeaway: Give your customer an out. Blame technology, blame a busy day, blame anything except the customer's decision. It preserves the relationship and makes returning feel natural.

5. Product-Related Subject Lines

Massdrop abandoned cart email with subject line asking if customer is still interested in a custom keycap set
Massdrop names the exact product in the subject line

Product-related subject lines include the actual item name or category the customer left behind. The logic is simple: if they added it to their cart, they wanted it. Naming the product resurfaces that original desire.

Examples:

• "Your {item} Would Look So Good on You"

• "What Did That {Product Name} Look Like Again?"

• "Still interested in the Massdrop x MiTo SA Pulse Custom Keycap Set?" (Massdrop)

• "The {Product Name} You Loved Is Still Available"

Why it works: Massdrop goes hyper-specific. Instead of a generic "you left something behind," they name the exact product, including the collaboration and model. For niche products with passionate communities (custom keycaps, specialty audio, limited drops), this specificity signals that the email isn't a mass blast but a targeted, relevant message.

E-commerce personalization examples consistently show that product-specific messaging outperforms generic messaging. When a customer sees the exact item they were considering, it triggers memory recall and reignites the purchase intent that initially drove them to add the item.

Key takeaway: Use dynamic product name insertion in your email platform (Klaviyo, Drip, Mailchimp all support this). A subject line with the exact product name converts better than any generic template.

6. Friendly Subject Lines

Chubbies abandoned cart email with casual subject line Howdy bud
Chubbies treats cart recovery like a text from a friend

Friendly subject lines make your recovery email feel like a message from a person, not a corporation. They break the fourth wall of transactional email and create a personal connection.

One important caveat: this only works if your brand already has a casual, conversational tone. A luxury brand sending "Howdy bud" would feel off. Know your audience first.

Examples:

• "Howdy Bud?" (Chubbies)

• "Where'd You Go?"

• "Hey, We Missed You"

• "Just Checking In"

Why it works: Chubbies owns the friendly approach across all their marketing. "Howdy bud" reads like a text message, not an automated email. At only 9 characters, it's extremely short for a subject line, which creates contrast against the longer subject lines surrounding it in the inbox. That contrast alone drives opens.

The catchy email subject lines show that conversational subject lines perform well because they activate a different mental model. The recipient processes it as interpersonal communication rather than marketing, which lowers their guard and increases the likelihood of engagement.

Key takeaway: Test a casual, short subject line (under 15 characters) against your standard template. If your brand voice supports it, you may see a significant lift in open rates from the inbox contrast alone.

7. Customer Service Subject Lines

Bonobos leads with helpfulness, not a sales pitch

Customer service subject lines reframe the abandoned cart email as a support interaction rather than a sales push. They acknowledge that something might have gone wrong and offer to help.

Examples:

• "Can We Help?"

• "Was There a Problem with Your Order?"

• "We noticed you haven't checked out. Just let us know." (Bonobos)

• "Having Trouble? We're Here to Help"

Why it works: Bonobos strikes the right balance. "We noticed you haven't checked out" is observational, not pushy. "Just let us know" positions the brand as an ally. This approach is particularly effective for brands where the checkout process involves decisions (size selection, customization, shipping options) that might stall a buyer.

Sometimes customers abandon because of a genuine issue: a promo code that didn't work, confusion about sizing, or a payment error. A service-oriented subject line addresses these friction points directly. It also builds long-term trust in your cart recovery process because even if the customer doesn't buy now, they remember that your brand offered help instead of pressure.

Key takeaway: Use customer service subject lines for your third email in a cart recovery sequence. By that point, if the customer still hasn't converted, a genuine help offer can address hidden objections that discounts can't solve.

8. Brand Voice Subject Lines

Your subject lines don't need a discount, a question, or a curiosity hook if your brand voice is strong enough on its own. Brands with a distinct personality can use their tone as the differentiator.

This approach works well for brands that have already built recognition and loyalty. A new store without established brand equity should stick to clearer, more direct approaches first.

Examples:

• "Wanna Know a Secret?" (Chubbies)

• "You're officially a part of the squad" (Maybelline)

• "Your future self will thank you"

• "This isn't goodbye"

Why it works: Chubbies and Maybelline both lean into voices that their audiences already recognize. "Wanna Know a Secret?" is playful and conspiratorial. "You're officially a part of the squad" uses inclusive language that reinforces community belonging. Neither mentions the cart, the product, or a discount, yet both create enough intrigue to drive opens.

Brand recognition acts as a pre-filter. When a customer already associates a brand with a positive feeling, the subject line doesn't need to do all the work. The brand name in the sender field and the familiar tone in the subject line work together. The email equivalent of seeing a friend's name on your phone: you pick up before reading the preview.

Key takeaway: Audit your last 20 marketing emails. If your subject lines could belong to any brand, your voice isn't strong enough for this approach yet. Build voice consistency first, then use it in cart recovery.

9. FOMO and Urgency Subject Lines

The Honest Company abandoned cart email about cart expiration and free shipping qualification
The Honest Company stacks urgency with a shipping incentive

FOMO (fear of missing out) subject lines create urgency by implying that the customer's cart, the product, or a deal is about to disappear. This taps into loss aversion, which behavioral economists have shown to be twice as powerful as the prospect of gain.

E-commerce brands typically create urgency in three ways:

Cart-centered urgency: Telling the customer that items in their cart will expire or be released back to inventory

Product-centered urgency: Warning about limited stock on specific items they added

Incentive-centered urgency: Offering a time-limited discount that expires within hours

Examples:

• "Your cart is about to expire"

• "Act Fast to Get 15% Off Your Cart!"

• "Your cart is about to expire, you may qualify for free shipping" (The Honest Company)

• "Only 2 Left in Stock"

Why it works: The Honest Company stacks two motivators: urgency ("about to expire") and incentive ("free shipping"). This dual approach gives the customer two reasons to act now. According to Rejoiner's abandoned cart email statistics, 44% of all abandoned cart emails use scarcity in the subject line or body as a conversion tactic.

Loss aversion drives the psychology. People feel the pain of losing something about 2x more intensely than the pleasure of gaining something equivalent. When a subject line says "your cart expires in 2 hours," the customer isn't thinking about what they'd gain by buying. They're thinking about what they'd lose by not buying.

Urgency also works for on-site recovery. Cart abandonment popup examples show that exit-intent popups with countdown timers can recover 5-15% of abandoning visitors before they even leave your site.

Key takeaway: Only use urgency if it's real. Fake scarcity erodes trust fast. If the item genuinely has limited stock, say so. If it doesn't, use cart expiration (which you control) rather than fabricating stock numbers.

10. Creative Subject Lines

Dyson abandoned cart email with creative subject line All Is Not Lost
Dyson's literary reference stands out in the inbox

Creative subject lines break every rule in this article. They don't mention the cart, don't offer a discount, and sometimes don't even make obvious sense at first glance. Their entire purpose is to stand out by being unexpected.

Examples:

• "Don't open this email" (REBEL8)

• "Olivia, You Know You Want This"

• "All Is Not Lost" (Dyson)

• "Plot twist: your cart still exists"

Why it works: Dyson's "All Is Not Lost" reads like a chapter title. It's literary, it's dramatic, and it reframes the abandoned cart as a narrative moment rather than a transaction.

REBEL8's "Don't open this email" uses reverse psychology, which can drive extremely high open rates but also risks backfiring if the email content doesn't deliver on the intrigue.

Most abandoned cart emails follow predictable formulas. When one breaks the pattern completely, it captures attention through contrast. The brain is wired to notice things that deviate from expected patterns, a phenomenon called the Von Restorff effect (isolation effect).

Key takeaway: Reserve creative subject lines for your most engaged customer segments. Customers who have purchased before can appreciate the playfulness. First-time abandoners need clarity over creativity.

11. Personalized Subject Lines

Personalized abandoned cart subject lines go beyond inserting a first name. The best ones combine the customer's name with product details, location data, or behavioral signals to create a subject line that feels individually crafted.

Before personalizing, segment your list. Sending "Olivia, Your Cart Needs You" to a contact named "[email protected]" breaks the illusion instantly.

Examples:

• "Olivia, Your Cart Needs You Badly."

• "Heard it's snowing in {Location}, get {product name} to stay warm"

• "{Name}, we saved your {product} for 24 hours"

• "{Name}, your {product category} picks are going fast"

Why it works: The weather-based example is advanced personalization that connects the customer's real-world context with the product they abandoned. If someone left a winter jacket in their cart and it's snowing in their city, that subject line becomes remarkably relevant. This level of personalization requires solid data infrastructure but the payoff is significant.

Personalized emails generate higher transaction rates. Name personalization alone lifts open rates by 10-14% on average. Adding product or behavioral data on top of that compounds the effect.

Key takeaway: Start with first name + product name personalization (most email platforms support this natively). Graduate to location and behavior-based personalization once you've built the data pipelines to support it accurately.

12. Emoji Subject Lines

Emojis in abandoned cart subject lines are polarizing. They can increase open rates by adding visual contrast in a text-heavy inbox, or they can make your email look like spam depending on your audience.

The key variable is your customer demographic. Younger audiences (18-35) generally respond positively to emojis. B2B buyers and older demographics tend to view them as unprofessional.

Examples:

• "🛒 Your cart misses you"

• "⏰ Hurry! Your Cart Expires Soon"

• "🚨 Don't let these slip away"

• "👀 Still thinking it over?"

Why it works: The single emoji at the start of a subject line acts as a visual anchor. In an inbox scan, the eye catches color and shape before reading text. A well-chosen emoji that relates to the product or emotion (a shopping bag, a clock for urgency, a gift box for offers) adds meaning without adding characters.

Emoji subject lines work through visual salience. In a list of plain-text subject lines, one with a colored emoji pops. But the effect diminishes as more brands adopt emojis. The differentiator now isn't whether you use emojis but whether the emoji adds genuine context. A random fire emoji adds nothing. A clock emoji before a time-limited offer reinforces the urgency.

Key takeaway: A/B test one emoji variant against a plain-text variant for at least 1,000 sends before committing. Test the emoji position (start vs. end of subject line) separately. Results vary wildly by industry.

13. Emotional Subject Lines

Dote uses humor and anthropomorphism for emotional impact

Emotional subject lines make the customer feel something: guilt, amusement, nostalgia, or even mild sadness. They anthropomorphize the cart or products, turning an inanimate transaction into a relationship.

Examples:

• "Your shopping bag has abandonment issues." (Dote)

• "UrbanDaddy: You've Changed"

• "Your items are feeling lonely"

• "We're not mad, just disappointed"

Why it works: Dote's "Your shopping bag has abandonment issues" is a standout because it's genuinely funny. It takes a psychological concept (abandonment issues) and applies it to a shopping bag, creating an absurd image that makes the recipient smile. Humor is one of the hardest things to execute in email marketing, and when it lands, it's incredibly memorable.

Emotional subject lines work through a mechanism called affect transfer. The positive emotion (laughter, warmth) generated by the subject line transfers onto the brand. The customer doesn't just open the email; they open it with a positive feeling that primes them for a purchase decision. UrbanDaddy's "You've Changed" plays on relationship language, creating a mild guilt response that's softened by the obvious humor.

Key takeaway: If you're going to use humor, commit to it. Half-funny is worse than not funny. Write 20 emotional subject line options and pick the one that makes you actually laugh. That's the one your customers will respond to.

Abandoned Cart Email Tactics That Increase Open Rates

Write Subject Lines in Title Case

There are three common formatting approaches for subject lines:

Title case: Capitalizing the first letter of each word ("Your Cart Is Waiting")

Sentence case: Capitalizing only the first word ("Your cart is waiting")

Lower case: No capitalization ("your cart is waiting")

Title case adds a professional, polished feel to subject lines. In my testing across multiple email marketing campaigns, title case consistently edges out sentence case by 2-5% in open rates for transactional emails like cart recovery. Lower case can work for brands with an intentionally casual voice, but it risks looking like a mistake.

Avoid Spam Folders

Your subject line can be perfect and still fail if it triggers spam filters. Three rules to follow:

• Avoid ALL CAPS words (one capitalized word like "URGENT" is borderline; two or more is risky)

• Limit exclamation points to one per subject line maximum

• Skip spam-trigger words like "FREE!!!", "Act now!!!", "Limited time offer!!!"

A detailed breakdown of why emails get flagged is available in our guide on why emails go to spam.

Send a Sequence, Not a Single Email

One abandoned cart email isn't enough. According to Klaviyo's benchmark data, e-commerce brands that send multiple cart recovery emails generate more revenue and see higher open rates than those that send just one.

A proven three-email sequence looks like this:

Email 1 (1 hour after abandonment): Straightforward reminder. Subject line: "You left something behind"

Email 2 (24 hours): Add social proof or product benefits. Subject line: "Still thinking about {product}?"

Email 3 (48-72 hours): Final push with offer or urgency. Subject line: "Last chance: 10% off your cart"

Subject Line Length and Performance

Klaviyo's data on subject line performance by type

Keep subject lines under 50 characters for mobile optimization. Most mobile email clients display 30-50 characters in the preview, so front-load your most important words. The product name or offer should appear in the first 30 characters whenever possible.

Offer Performance by Type

Not all offers perform equally. Here's how different incentive types compare based on industry data:

Offer Type Open Rate Click Rate Revenue Per Recipient
Percentage-based discounts 36.55% 10.35% $2.81
Dollar-based discounts 42.78% 8.99% $15.91
Free shipping 43.39% 12.53% $3.07

Dollar-based discounts generate the highest revenue per recipient ($15.91) by a wide margin. Free shipping drives the highest click rate (12.53%). Test both against your average order value to determine which works best for your store.

How to A/B Test Your Abandoned Cart Subject Lines

Writing great subject lines is only half the job. The other half is testing them systematically. I've run A/B tests on cart abandonment emails for three years, and here's the process that consistently produces results:

1. Test one variable at a time. If you change both the tone and the length, you won't know which variable caused the performance shift. Test "curiosity vs. straightforward" in one round, then "short vs. long" in the next.

2. Set a minimum sample size. You need at least 500 sends per variant to reach statistical significance. For stores with smaller lists, extend the test window rather than reducing the sample.

3. Track conversions, not just opens. A clever subject line might get a 60% open rate but a 0.5% conversion rate because the email content didn't match the subject line's promise. Align your subject line with your email body.

4. Document everything. Build a testing log with the date, variants, sample size, open rate, click rate, and conversion rate. After 10 tests, you'll have a data-backed playbook specific to your audience.

According to Stripo's email statistics analysis, the typical conversion rate of abandoned cart emails is 10-15%, placing them among the most effective email automation types. Consistent A/B testing can push your rates toward the higher end of that range.

Choosing the Right Subject Line for Your Brand

After analyzing these 50+ abandoned cart subject lines across 13 categories, three patterns stand out.

First, specificity outperforms cleverness. Subject lines that name the product, state the offer, or address a real objection consistently convert better than vague creative approaches. Casper's "Come Back to Bed" works because it's both clever and specific. Most brands should start with specificity and layer in creativity later.

Second, your email sequence matters more than any single subject line. A three-email flow with a straightforward first email, a benefit-driven second email, and an urgency-driven final email covers multiple psychological triggers and customer segments. Don't put all your recovery weight on one message.

Third, match the subject line to the abandonment reason. Use your cart abandonment statistics to identify whether your customers are leaving because of price, friction, or distraction. Then select subject line categories that address those specific triggers.

Start with the FOMO subject lines and straightforward categories. Test one new category each month. Track your results. Within a quarter, you'll have a subject line playbook built on your own data rather than generic best practices.

FAQ About Abandoned Cart Subject Lines

What are the best abandoned cart subject lines for 2026?

The best abandoned cart subject lines for 2026 combine personalization with a clear value proposition. Based on current data, straightforward subject lines like "Your {Brand Name} Basket" achieve the highest conversion rates (32.73%), while curiosity-driven lines like "Oops, Did Something Go Wrong?" reach the highest open rates (66.28%). The right choice depends on whether you're optimizing for opens or conversions. Test 2-3 categories from this list against your current subject line to find what works for your specific audience.

How do you write an effective abandoned cart email?

An effective abandoned cart email has four components: a subject line that gets opened (use the examples above), a clear product reminder with images of the abandoned items, a single call-to-action button that takes the customer directly back to their cart, and a reason to act now (scarcity, discount, or free shipping). Send the first email within one hour of abandonment. The email body should be under 150 words.

What is an example of an abandoned cart email flow?

A standard abandoned cart email flow consists of three emails. Email one (sent 1 hour after abandonment) is a friendly reminder with the subject line "You left something behind." Email two (sent 24 hours later) adds social proof or product benefits with the subject line "Still thinking about {product name}?" Email three (sent 48-72 hours later) includes a discount or urgency with the subject line "Last chance: 10% off expires tonight." Each email in the sequence targets a different psychological trigger to maximize recovery rates.

How do you personalize abandoned cart email subject lines?

Start with the customer's first name, which most e-commerce personalization platforms insert automatically using merge tags. Then add the product name or category they abandoned. Advanced personalization includes location data ("Snowing in Boston? Don't forget your jacket"), browse history ("Back for the running shoes?"), and loyalty status ("As a VIP member, your cart is saved for 48 hours"). Each layer of personalization increases relevance and open rates.

What makes an abandoned cart subject line click-worthy?

A click-worthy abandoned cart subject line does one of three things: it creates a curiosity gap the customer needs to close, it states a clear benefit (discount, free shipping) that addresses a known objection, or it triggers an emotional response (humor, urgency, empathy). The best subject lines are under 50 characters, use the customer's name when possible, and match the brand's overall voice. Avoid generic phrases like "complete your purchase" that don't differentiate your email from every other cart recovery message in the inbox.

How can I combine email recovery with on-site popups?

The most effective cart abandonment recovery strategy uses both on-site popups and email sequences. An exit-intent popup captures the customer while they're still on your site, offering an immediate incentive to complete the purchase. If they leave anyway, the email sequence follows up. This two-layer approach recovers more customers because some people respond better to real-time offers (popups) while others need time to reconsider (emails). Tools like Popupsmart let you set up exit-intent triggers without any coding.
