The competition for inbox attention is fierce, and the subject line is your first (and sometimes only) shot to make an impact. A well-crafted subject line can be the difference between your email being opened or being lost in the shuffle.
Today, we're thrilled to introduce another new AI-powered tool in MailerLite that takes the guesswork out of creating powerful, engaging subject lines.
Meet your new AI subject line generator! The innovative new feature that writes multiple subject lines for you based on what you need. Are you ready to save tons of time, increase your open rates, and make the most of your email campaigns?
Let’s take a look at how it works!
The new email subject line generator takes the challenges of crafting the perfect subject line and turns them into opportunities. Here are a few reasons why you’re going to love using this new tool:
Writing the perfect subject line can sometimes take as long as writing the email itself! But with the AI subject line generator, you can create a range of engaging subject lines in a matter of seconds. This means more time for creative tasks that can’t be automated.
There’s no one-size-fits-all when it comes to email marketing. Every audience is different. With the help of your AI subject line generator, you can tailor each subject line to your campaign and audience, leading to higher relevance and, ultimately, better open rates.
Struggling with writer's block? The AI subject line generator offers a plethora of creative possibilities. It can generate a variety of subject lines from a single prompt, providing you with a bunch of options that you might not have thought of on your own.
A well-crafted subject line can significantly boost the success of your campaign. With AI-generated subject lines, you'll benefit from optimized language that catches your audience's attention and encourages them to open your email.
The AI subject line generator is available on all Advanced plans. But for a limited time, you can try it for free on the new version of MailerLite! We’ve given all MailerLite accounts free credits to try out our new AI features (including free plan users). After all, seeing is believing.
To use the AI subject line generator all you have to do is create a new campaign or workflow email. Then, when you reach the ‘Subject’ field, click ‘Suggest’. A window will pop up where you can select your desired tone of voice and campaign type for context.
Then all you have to do is enter your prompt and hit ‘Generate’ to see a variety of subject line options.
Pretty cool, right? You can either go with one of the subject lines generated or click ‘Regenerate’ for a fresh batch.
Sign up for a free MailerLite account and get free credits to use the AI subject line generator and AI writing assistant! Plus you can try even more premium features, like multi-trigger automation, pre-built templates and more, free for 30 days.
Having the ability to select your desired tone and campaign type helps the AI subject line generator understand your desired messaging goals. To give you a taste of how it can create lines based on specific requirements, we did a few experiments of our own.
Below are some examples of subject lines generated in MailerLite.
Sending promotional emails can be tricky, especially if the hard sell isn’t really your thing. Luckily, with your new AI generator, you have an in-built sales team to do the hard work for you.
In the example above, we opted for a friendly tone to generate a subject line for a promotional email. Because we told the subject line generator what the offer and target audience are, it was able to bake in specific campaign information.
“Write a subject line promoting 15% off my leadership e-book titled "Leading Leaders" targeted towards female entrepreneurs”

But what if you’re looking for something with a bit more zing?⚡
Well, let’s take a look at what happens if we input the exact same prompt, except this time we’ll select the ‘Catchy’ tone.
The same promotional information is relayed but in a totally different style.
Not sure which tone of voice resonates best with your audience? Create an A/B split test campaign and see which one gets the most engagement!
The AI subject line generator can also lend a helping hand next time you want to announce a new product or feature.
In this example, we included in our prompt that the goal is to get users to try our new feature. With that in mind, we made sure to choose the ‘Persuasive’ tone.
“This campaign is announcing our new AI subject line generator. The goal is to get users to try it.”

“Given the topic of A/B testing for landing pages, write a compelling subject line targeted towards small businesses.”

Writing an eye-catching subject line for your next event just got so much easier. All you need to do is give your subject line generator a few key pieces of information and let AI do the rest!
In the example above, we wanted something a little more professional. We also limited our prompt to key information and keywords. It doesn’t take a creative mastermind to prompt this AI text generator. Take a look below at how stripped-back this AI prompt is.
“Webinar invitation on AI in email marketing. Get people excited for a surprise guest.”
…and how put together the AI-generated subject lines are!

Another great way to use the AI subject line generator is for survey emails. In this example, let’s take a look at how different keywords can affect the output.
In the prompt above, we included that the goal was to make the subject line ‘intriguing’.
“Annual survey to gauge customer happiness for a project management app. The goal is to make it intriguing so subscribers open the email.”

Now let’s see what happens if we tweak that prompt, to make it more exciting. (For the sake of science, we’ll leave the tone and campaign type as they are).
“Annual survey to gauge customer happiness for a project management app. The goal is to make subscribers excited to open the email and reveal the survey.”

Just when you thought it couldn’t get any better… Yep! You can use AI suggestions on your workflow email subject lines too. And what better way to take advantage of that than in your abandoned cart emails.
Remember to test out other tones until you find the subject line that suits your brand’s abandoned cart emails.
“Casual subject line question for an abandoned cart email.”
Oops! Did something go wrong with your shopping cart?
Missing something? We saved your cart for you!
Did life get in the way of your shopping spree?
Is your cart feeling lonely without you?
Hey there, did you forget something on your shopping list?
Finally, you can harness the power of AI to re-engage subscribers that haven’t been opening your emails in a while. If you’re offering an exclusive promotion for inactive subscribers, make sure to include it in your prompt!
The more specific your prompt, the better.
"For people who haven't renewed their gym membership. Offering 3 months at half price if they sign back up before the end of the month. Lead with the benefit and focus on the reader."
