Though there is always much effort in building an efficient email list, sending emails is not enough for this process. First, you need to get people to open the emails you have sent.
According to these statistics, you need to create strong, compelling, interest-provoking, and informative email subject lines to make your emails more meaningful.
The first thing you should know is that a good subject line should be short, clear, specific, simple, logical, and personalized
MailChimp’s email subject line study found out that the short and descriptive subject lines consisting of visual pizzazz with a bit of humor convert better.
Also, to make people open email campaigns, natural human tendencies and psychological methods need to be focused on.
Another point is customization for summarizing great content with a few words and making it attractive.

Although it may seem very easy, some steps are recommended.
Loading the subject line with action-oriented verbs in the beginning, can drastically help open rate and click-through rates increase. And you can create much more attractive subject lines by using action verbs.
Short instructions generally work well in email subject lines because of the limited space to convince subscribers to open your email.
Some basic call-to-action examples are;
50 characters are the ideal length for a subject line. On the other hand, more than 50 characters can scare or bore people and make them distracted.
Details should be in the message, and the subject line should only summarize what is told in the statement.
Additionally, using sales language is a point to avoid while simply reflecting your brand.
Otherwise, emails may go down the drain since they are considered spam with many unnecessary details and explicit marketing.
Studies show that 55% of emails get opened on a mobile device. Therefore, the look on computers and mobile devices can change based on the width of the screen.
As an example to observe:
While most businesses realize that their emails need to be optimized for mobile devices, they forget about the subject lines.
Overall, the shorter the subject, the higher the open rates.
As Jim Rohn said, “Without a sense of urgency, desire loses value.”
In order to have a clear subject line, you should trigger your customers with an immediate call to action.
Try to make them think about what if they don’t act fast, or what if the product with limited availability runs out, intuitively.
Subject lines including words that imply time sensitivity, like “urgent,” “breaking,” “important,” or “alert,” are proven to increase open email rates.
Sidenote: The same factor works for getting more leads from email popups. You should use Scarcity, Urgency, and Exclusivity to increase conversions.
A limited-time offer is any kind of discount, deal, special gift, or reward a buyer can get if they purchase from you during a specific time period.
Consumers have a burning desire to jump on exclusive deals and get their hands on something special before they miss out.
Most customers abandon their carts before completing the purchase; in such cases, you should use the urgency and scarcity method with creative abandoned cart subject lines.
You can also make them feel like sharing something special to increase audience engagement when you offer an exclusive deal for a limited time.
E.g., ” Don’t tell anyone. Special discounts are just for you!”
If your subject line makes your subscribers smile, then they’ll tend to open it.
Being humorous requires a bit more thought and creativity, but it can really pay off in terms of your open rates and increased sales.
Conveying a message with a little mystery is always a good idea. You should implicate the benefit from opening that particular email by promising to give helpful information.
After providing that, you’ll see the increase in your conversion rates. However, be careful not to have too obscured subject lines. Otherwise, you may be considered spam.
Questions trigger answers. Therefore, to increase curiosity;
According to a study by Marketing Dive, personalization of email subject lines improve the open rate at the ratio of 50%.
When inbox folders are first opened, we all tend to scan the subject lines of the emails and eliminate the promotional ones or spam. If you feel like you get an email from a friend, you will probably open it.
There are some outstanding points to consider to increase your email open rates:
Don’t forget, if you make your subscribers feel special and niche, they are more likely to become your loyal fans, loyal customers, and followers, which is the main goal of all marketing efforts.
Set your sender name appropriately. It is essential to build trust with your subscribers.
” [email protected]” is an excellent example of an inviting sender name. Isn’t it? 🙂
Also, avoid the ‘no-reply’ sender name. People may consider you spam.
In order to prevent that, never use something like that:” [email protected]”
According to a report by Experian, using emojis in your subject lines can increase your open rates by 45%.
A well-placed emoji can be great for building a close relationship with your subscribers. Note that the email subject lines with emojis beat out the plain text ones!
The most popular emojis used in email subject lines are as follows based on Omnisend’s article:
|🎁||For bonuses and gifts|
|🚨||For sales and time-limits in campaigns|
|❤️||For love, happiness, gratitude|
|😮||For a surprise and great chances|
|🎉||For celebration and surprises|
|👉||For directing and concentrating|
|😍||For adoration, good emotions|
|⏲️||For limitation of time and expirations|
|🔥||For appealing news and offers|
|✅||For positiveness, verification and completing task|
Your emoji usage must be relevant to the content of your email and your email subject line. Otherwise, it would seem insignificant.
✅ “Pizza party this Saturday! 🍕🎉” → These clarify what your email is actually about.
❌ “Springfield Elementary PTA Newsletter 🍕🎉” → These seem out of place and confusing since these have nothing to do with the subject line.
A controversial subject line can be a negative idea or outcome in your niche target or one of your audience’s major pain points. If you are not sure about your subscribers’ tastes yet, things can take a turn for the worse.
However, when executed strategically, a controversial subject line can be more effective than you think.
If you’re confident in knowing your audience’s interests and perceptions, you may use controversial subject lines in order to grab their attention.
Take time to understand your subscriber’s nature and then (if your business context is suitable) use shock, stimulation, or controversy in your subject lines. For example;
In a study conducted by Christopher Packham in MedicalXpress, “Numerosity as a primary visual property can be formally described in terms of topological invariants.”
So, if you add numbers into your subject line, you grab your subscribers’ attention, as our brains are naturally curious about numbers. Also, that kind of subject line is always easy and quick to read.
Additionally, creating a subject line with the initial of a number or a percentage may be very effective.
When it comes to offers, the discount price should always be front-loaded. To exemplify, write “50% Off Flash Sale” rather than “Flash Sale: 50% Off”.
By using numbers in your subject line, you don’t just grab their attention of them, but also you create a perception that your content is unique.
A lot of companies still send emails with a subject line like;
“OPEN NOW AND GET 80% DISCOUNT!!!!!”
Unfortunately, it’s not working. It’s actually distasteful…
No one likes to be yelled at, and these kinds of subject lines make people rub the wrong way… You should always use engaging and human-like language to make people comfortable and get their attention.
Writing your email subject line using upper-case letters seems like you are commanding, yelling at, or desperately seeking attention.
Also, the first letter of each word should be capitalized, and the others should be lowercase.
Be careful about capitalizing your email subject line, or you will be perceived as careless or offensive.
The main reason for people to subscribe to an email list is that they want to be kept informed about a given topic, product, or offer.
Therefore, subdividing your audience into groups will help you to send the suitable topics to the right people.
Otherwise, people unsubscribe from your list due to receiving many unwanted and irrelevant messages. This is why you should never purchase an email list from another company to have a customer base.
Instead, there are some email list-building methods if you are interested.
If you have any problems with segmenting your customers, you can categorize subscribers based on interests by offering opt-in segments on your email subscriber form.
You should use timely headlines or compelling trending topics to grab your subscribers’ attention.
Moreover, you need to make a wise schedule to send your emails. No one wants to get an email from you three times a day. Have a weekly and monthly plan to make your subscribers your loyal fans.
So when is a good time? Good email times to send are typically daytime hours.
For example, if you want to take advantage of an alert person who will likely get a new email notification, this isn’t likely to happen at 3 am.
Therefore, the best play here is to extract your subscribers’ location data and determine their available hours.
Google is a data-driven beast, not just in its search algorithm but also in its email algorithm.
If you come up with deceitful email subject lines, your initial open rates may rise, but eventually, your emails will be cast into the spam folder.
It is because Google collects complaint data from your subscribers, and if you lie to them, they complain, increasing the risk of being flagged as spam.
So, use accurate subject lines. Be sure that your subject line can be both curious and enticing without being deceitful.
Don’t make false promises to get your email opened. This is not good for your reputation and trustworthiness.
If you want to build emotional contact with your subscribers, better ask for their intentions.
Some steps can be done:
These ways can increase subscriber engagement with your email campaign and trigger your email open rate with appropriate and emotional subject lines.
There is no better approach than ideas coming from your customers who daydream about the future and will consume your marketing efforts.
“If-then” statements are *extremely practical triggers for behavior change and habit formation.**
The human brain is highly receptive to conditional expressions. Hence, You may offer something valuable to your subscribers by using if-then subject lines by determining your segmented subscribers’ needs and delivering the solution.
The key to an effective “if-then” statement is to make sure the “if” part is true for your audience and the “then” part creates a solution by purchasing your products or services offered.
Humans tend to think they’re above average at most things, which is called Superiority Illusion. So, you should give a sense that you support your subscribers in what they want to achieve.
To help your customers reach their goals through your offerings and provide what they need to improve their skills, you have to get to know your subscribers in terms of their interests, accomplishments, and failures.
Once you know your audience, use your knowledge about them to craft a subject line that commands they might be doing it wrong or fitting in with the “status quo.”
Then, create your email subject lines based on these characteristics of your segmented people.
Occasional subject lines make people smile, arouse curiosity, and click on the email because they are usually in a good mood these days.
So, benefit from it! Remind yourself with a kind, friendly, passionate, and caring approach.
Retargeting emails are sent to subscribers when they fail to complete an action, like abandoning their cart or failing to purchase after their free trial or unsubscribe themselves from your list.
You can write effective retargeting subject lines by overcoming objections, offering something to sweeten the deal, or saying that you have corrected your mistake.
You can also create an email marketing campaign using the method of Win-Back for customer retention.
To figure out which subject lines are best for your audience, you should definitely A/B test your emails.
Though it may take time to understand the proper style of subject lines for your visitors, you need to be patient.
It’s important to decide on what you consider success before you run an A/B test.
First, look at your historical open rate, and then decide how much improvement you want to see.
Most email campaign software has built-in tools for A/B testing. For example, you can use Campaign Monitor, MailChimp, or Active Campaign to run A/B testing.
If your email campaign software doesn’t have specific support for A/B campaigns, you can set one up manually.
