Frequently Asked Questions
Are subject lines generated by AI?
No. They use curated template patterns with your topic and audience inserted. This runs entirely in your browser with zero API calls.
What is the ideal subject line length?
Most email clients display 40-60 characters before truncating. The character count shown helps you pick lines that fit mobile screens. Under 50 characters is optimal.
Can I customize the templates?
The generated lines are fully editable after copying. Use them as starting points and tweak wording, add personalization tokens, or adjust length to fit your brand voice.
