subject lines

Message preview text

Subject lines are the brief text headers that identify the topic of an email or message thread.

They appear in inbox listings before the message is opened, serving as both label and lure: Write a compelling subject line to improve open rates.

A good subject line is specific enough to be useful but concise enough to display fully on mobile screens.

In email marketing, subject lines receive obsessive attention as the primary factor determining whether messages get read or ignored.
