Subject Line
A subject line is the short title of your email that shows up in the inbox. It gives people a quick idea of what the email is about and helps them decide if they will open it or ignore it.
A subject line is the title of your email. It is the first thing people see in their inbox next to your name. In a busy inbox, people skim subject lines to decide what to open. A clear subject line gives them a simple reason to choose your email.
Subject lines matter because they affect opens, clicks, and trust. A helpful line sets an honest promise about what is inside the email. When the subject and content match, people feel more confident about your messages. Over time this can improve your sender reputation and keep more emails out of spam.
A practical way to write better subject lines is to focus on one main benefit. For example, instead of writing "March newsletter", try "New email templates to speed up your next launch". Keep it short, specific, and easy to scan on mobile. You can also test a few versions with small groups to see which one gets the most opens.
