Keep It Short

More than 40% of newsletter subscribers open emails on their mobile devices first. That’s why it’s better to make the subject line short, so it isn't cut off automatically. Besides, not all the users tend to read them up to the end, moreover, if it does not grab attention. Make the first words the most powerful and informative.

Have a Balance Between the Subject Line and Preheader

Don’t forget about the preheader text that is displayed near the subject line. It’s like a preview of your email content explained in several words. Don't make it the same as the subject line.

Accompany your subject line with a preheader

Fill in the Sender's Field Correctly

  1. If you address your email from yourself, then enter your first and last name. 

  2. If you address your email from a company, then enter the name of the company.Sender's field

Use Numbers

We like numbers because they provide us with something concrete, not abstract information. Numbers give us a better idea about a new topic.

Create a Sense of Urgency

Urgency is a great trick played by all the marketers during sales, discounts, especially on Black Friday. Due to the sense of urgency, many people make impulse purchases.

It will help you to discover the best practices for specific segments of your mailing list. Read here how to create and send an A/B test in SendPulse.

SendPulse instruments for high-performing subject lines

We offer several professional instruments to increase your subject line performance totally for free.

Personalization and Smart Personalization

These instruments involve inserting personal information about subscribers into a subject line, for example, name, gender and location. This makes an email relevant for each recipient and increases their engagement.

Smart personalization is useful when you don't have the same information about all of your subscribers, for example, their name. In this case, you can specify the text for those users. Thus, every subscriber receives a personalized message.

Split-testing

This is a form of research that helps determine the most effective variant of the element being tested. Create different versions and test each one to see which one performs better.

Our free pricing plan will help you enjoy all the benefits of email marketing. Have less than 2500 subscribers? Send 15,000 emails for free every month!
