Subject line

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

You should take special care of your subject line. Just imagine the number of emails appearing in your subscribers' inboxes every day. In fact, we read them when having a free minute.

Not even a task but a challenge!

  • Keep it short

More than 40% of newsletter subscribers open on their mobile device 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.


  • 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. Don't make it the same as the subject line.

  • 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

People are curious that is why secrets and mysteries will arouse interest.


  • Ask

Question in the subject line will make a recipient feel a real communication with you. They will answer it or find the answer in your email.

We like numbers because they provide us with some concrete but not abstract information. Numbers give a better idea about some issues.
