As you know, your subscribers receive tons of emails. That’s why you only have one chance to grab the attention of your readers. Experts don’t recommend writing long subject lines: 60-70 characters is enough. Also, keep in mind the fact that your emails should look good on mobile devices. To check this, just send a test e-mail.
The subject should be understandable and inform the reader about the content. Also avoid traditional spam words like “cheap”, “free”, “last chance” etc. Also, you should alternate the subject lines so they won’t bore your readers. “The best blog articles of September” is dull and only worsen the open rate. It is essential to motivate the subscriber to open your letter. This motivation can be achieved in different ways: through scarcity/by curiosity/through personalization and emojis.
Our survey has shown that the majority of editors like to use emojis in the subject line or in the body of the newsletter.
