Subject line

The subject line is the part of the email that the subscriber sees when he or she it lands in their inbox. From the subject line, subscribers judge the email and decide whether to open it or not.

Here are some examples of email subject lines that subscribers really click:

Marketers have found that emails with personalized subject lines are 26% more likely to be opened.


  • Keep it short

More than 40% of newsletter subscribers open on the newsletter on their mobile device first. That’s why it’s better to make the subject line short, so it isn't cut off automatically.


  • Make the balance between 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.

  • When you fill in the sender’s field, follow these rules:

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

- If you address your email from a company, then enter the name of the company.


  • Make it intriguing


  • Ask


  • Use numbers


  • Create a sense of urgency
