What is a good subject line?
A good subject line is one that compels subscribers to open their email, thus increasing your email open rate.
A good subject line is under 40 characters, ideally. It’s short, is relevant to the email body and also hits home - if it's personalized, and sent at the right time and to the right person, it can increase open rate as well as conversion rates.
Importance of email subject lines:
Email subject lines are so important because they are the first thing that a subscriber sees when they receive an email notification. It is the only thing that is visible in the inbox at the top, along with preheader text, but the email subject line is what makes or breaks your email open rate.
