About AI email subject lines
Generate five to ten subject line options from a short description of your email. Each option targets a different angle - direct, curious, urgent, friendly - so you can pick the one that suits the audience.
Frequently asked questions
What length should an email subject be?
Under 50 characters so it doesn't truncate on mobile. The tool defaults to that range.
Should I use emoji?
In B2C marketing yes, modestly. In B2B and cold outreach, no - they look unprofessional and trigger more spam filters.
