Types of Abandoned Cart Subject Lines

1. Straightforward Subject Lines

Kate Spade's abandoned cart subject line

When writing a straightforward abandoned cart subject line, there should not be any unnecessary words and you should keep personalization natural.

Straightforward subject lines are for simply reminding your customers about the products they left in their online shopping carts.

  • Did You Forget This?

  • You Left Your {product name} Behind!

2. "The Offer" Subject Lines

Chubbies' abandoned cart subject line

Who does not like a discount or free shipping?

Some of your customers might have left because of the shipping cost or the cost of the product.

In this case, you can win them back by kindly bribing a special offer.

Even if the reason behind abandoning the cart was not related to the price, including your offer in the subject line can grab the customer’s attention.

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

  • Act Fast to Get 15% Off Your Cart!

3. Curiosity Subject Lines

Now, this is the opposite of a straightforward subject line.

The aim here is to capture your customer’s attention or interest by piquing curiosity and get them to click the email and read the well-written copy.

  • A Gift for You

  • Olivia, Continue Shopping with a Discount

4. Suggestive Subject Lines

Adidas' abandoned cart subject line

In suggestive subject lines you assume that rather than other reasons such as shipping cost or product price, your customer simply forgot to complete the purchase.

You remind them of the abandoned shopping cart.

  • Forgot something?

  • Olivia, You’ve Left Something Behind

Massdrop's abandoned cart subject line

Here’s simple logic; if the customers added certain products to shopping carts then they are interested in those products.

Through product-related subject lines, you aim to resurface the initial want or need for those products by including the product name in the subject line.

  • Your Would Look So Good on You

  • What Did That Look Like Again?

6. Friendly Subject Lines

Chubbies' abandoned cart subject line

Friendly subject lines create a personal level in your relationship with your customers, and they do not sound like mere transactional messages.

You need to keep in mind that your brand needs to have a certain tone when interacting with your customers.

So, if your brand has more of a formal tone, then a friendly subject line might be inconsistent for your brand voice.

Know your audience and decide on your tone according to that.

Chubbies is a great example of friend subject lines.

  • Howdy Bud?

  • Where’d You Go?

7. Customer Service Subject Lines

Bonobos' abandoned cart subject line

If customers abandoned their carts, this might have resulted from a problem occurred during the checkout process.

Reaching out to help your customers can be a great way to increase conversion. You can simply ask what the issue was and try and solve it.

  • Can We Help?

  • Was There a Problem with Your Order?

8. Brand Voice

Your subject lines do not need to include an offer to get your customers to click the email.

If your brand has a unique personality, then you can write your subject lines in that tone.

It might be humorous, conversational or friendly. However, it works well, only if you know your audience and have a consistent tone.

  • “You’re officially a part of the squad” By Maybelline

9. Fear of Missing Out (FOMO) Subject Lines

The Honest Company's abandoned cart subject line

It’s a psychological trick to get your customers to purchase by giving them a fear of missing out.

A lot of ecommerce brands generate urgency in their subject lines in three ways.

Urgency centered on the cart: By telling that the items in the cart are about to expire

Urgency about specific products: By informing about limited items in their cart

Urgency with an incentive: By offering discounts on completing their purchase in limited time

  • Your cart is about to expire

  • Act Fast to Get 15% Off Your Cart!

Then get personal with your customers. Instead of addressing them in general, try to include their first name in your subject lines.
