How it works
Type your sender name, subject line, and preview text, and see them in Gmail, Apple Mail, and Outlook, on desktop, and on a phone, cut off where each inbox cuts them.
The preview text is the grey line after the subject. It’s the second thing people read, so it’s worth writing on purpose.
FAQs
How long should an email subject line be?
Aim for under about 35 characters if most of your list reads on a phone. Gmail on a phone shows roughly that much.
What is preview text?
The short line an inbox shows after the subject. Most email tools let you set it, and if you don’t, the inbox grabs the first text in your email.
Do emoji work in subject lines?
In most inboxes, yes. They look a little different on every system, and one is plenty.
