How to Write Engaging Subject Lines for Email Campaigns


December 1, 2022

These tips for writing engaging subject lines can help you win some much-needed attention.

Subject lines are the first, and sometimes only, thing your subscribers see when your email lands in their inbox. So it’s no surprise that coming up with engaging, interest-piquing subject lines can feel like a daunting task.

The good news is, there are some tried-and-true methods for subject line success. In this blog post, we’ll share four tips for writing engaging subject lines that will improve the performance of your email marketing campaigns.

How to write engaging subject lines and get your emails opened

Your email subscribers are bombarded with messages every day, so it’s important to make sure your subject line stands out from the rest.

A great subject line will pique the recipient’s interest and make them want to open your email. A poorly written one will send your email straight to the trash.

So how do you write an engaging subject line that will get your email opened? Here are four tips to help you get started:

1. Keep it short and sweet.

The average person receives 121 emails per day, so it’s important to make sure your subject line is concise and to the point.

Studies have shown that shorter subject lines are more effective than long ones, so try to keep yours under 50 characters.

This can be a challenge, but it’s worth it – emails with shorter subject lines have been shown to have higher open rates.

2. Use powerful words.

The words you use in your subject line can have a big impact on whether or not your email gets opened. Some words are more likely to grab attention than others, so choose yours carefully.

Words like “alert,” “breaking,” and “urgent” tend to work well, as do numbers and symbols (like $ or %). Just be careful not to overdo it – too many exclamation points or all caps can come across as spammy.

3. Personalize it.

Make sure your subject line sounds like it was written specifically for the recipient by including their name or other personal information (like their city or company). This helps create a sense of urgency and importance that will encourage them to open your email right away.

You can also use segmentation to send personalized emails based on things like location, purchase history, or past engagement with your brand. Doing this will require extra effort upfront, but it’s worth it – personalized emails have been shown to deliver significantly higher open rates than generic ones.

4 . Be clear about what’s inside.

Your subject line should give recipients a good idea of what they can expect to find in your email. If you’re offering a discount code, say so in the subject line like so:

“Save 20% on Your Next Purchase”

If you’re sharing new product information, let them know what it is, immediately like:

“Introducing Our Newest Addition”

And if you’re sending a time-sensitive message, make sure they know that too:

“Last Chance! Sale Ends Tonight at Midnight”

Being clear and specific about what’s inside will help increase both your open and click-through rates.

Other ways you can optimize your email marketing campaign

In addition to following the tips above for writing engaging subject lines, there are a few other things you can do to optimize your email marketing campaigns:

1. Use a responsive design.

More and more people are opening email on their mobile devices, so it’s important to make sure your emails are formatted correctly for small screens.

A responsive design will automatically adjust to the size of the screen, making it easy for recipients to read your messages no matter how they’re viewing them.

2. Test different subject lines and send times.

Not all audiences respond the same way to different subject lines and send times, so it’s important to test out different combinations to see what works best for your subscribers.

You can use methods like A/B testing to compare two different versions of a campaign and see which one performs better.

3. Include images and videos.

Images and videos can be a great way to capture attention and engage recipients in your message. They also take up more space in an email than text-only messages, so they’re more likely to be noticed.

Just make sure they’re relevant and add value to the content of your email – too many irrelevant images can actually hurt your click-through rate.

4. Use call-to-action buttons.

Buttons are a great way to encourage recipients to take action based on the content of your email. They stand out from the rest of the text and make it easy for people to know what you want them to do. Just be sure not to overload your emails with too many buttons – stick to one or two at most.

5. Keep track of results and optimize accordingly.

The only way to know if your email marketing campaigns are working is to track their results over time. This means keeping an eye on things like open rates, click-through rates, unsubscribe rates, and conversion rates.

Based on this data, you can then make changes (or keep the same strategies) that improve the performance of your campaigns

Key takeways

A great subject line is essential for any successful email campaign – after all, it’s the first thing recipients see when they open their inboxes. By following these four tips, you can double your open rates by piquing curiosity. Some other tips to mind when running email campaigns are:

  • Deepen your mailing list. Make sure to have calls-to-action in your website content to urge readers to subscribe to your newsletters.
