How do you write a subject line for a newsletter?

Do you often find yourself overthinking about your newsletter subject line? Or maybe you give it less of your time and thought? Newsletters remain to be an effective way to build relationship with an audience. They complement your website thus the need to ensure its content and headline resonates with the audience.

Email subject lines weigh as heavily as the content. They determine whether or not your content will be read. In this post we’re going to discuss how you can survive the inbox congestion and come up with the best newsletter subject lines – one that won’t lead you to the spam folder and that will make your subscribers confident to open your emails.

First, let’s jump right into the guideline you should consider:

Newsletter subject line best practices with examples

 1. Be straightforward

Don’t keep them guessing or be too crafty to present the actual newsletter content. Your subscribers will value your newsletters if they are descriptive as opposed to a generic subject line they’ve seen in a bunch of other emails. Some generic subject lines are such as ‘January newsletter  and This week’s newsletter.’

 2. Avoid repeating information

Make good use of the 30-50 characters space you have by avoiding repeated information. For instance, writing the name of your business in the subject line yet the users have/ will see your details on the email and senders’ information.

 3. Personalize it

There’s an argument for and against the use of a recipient’s first name of the subject line. While it personalizes the message, users are wary of newsletter subject lines that include their name as they may already know the email wasn’t specifically to them but hundreds or thousands of other subscribers.

Remember to also address their pain points and this is made possible through segmentation.  And lastly, avoid writing the subject line in caps as it creates an impression of yelling at your subscribers.

 4. Include a call-To- Action

Go ahead and compel them to take action. It prompts urgency that increases the open rate. As a word of caution, you’ll want to avoid subject lines that sell what’s inside and go for those that tell what they can expect.

Most call to action also alludes to scarcity thus the sense of urgency.

Here are some examples below:

 5. Use numbers

Numbers and data make the newsletter specific, digestible and improve on the credibility of your content. So go ahead and include the numbers.

 6. Maintain relevancy

Segment your email and avoid the tendency to send your newsletters to everyone. For instance, new subscriber emails are different from your repeat customer emails. Make their subject lines relevant according to their segment.
