Frequently Asked Questions

What makes a good email subject line?

Clarity, relevance, and a reason to open. The best subject lines are specific, hint at value, and feel personal rather than mass-marketed.

How long should an email subject line be?

Aim for 40–50 characters (6–8 words). Shorter lines often perform better on mobile where screen space is limited.

Should I use the recipient's name in the subject line?

Yes, when it's natural. Personalized subject lines average 26% higher open rates. But use it sparingly — it loses impact if overused.

Is this tool free to use?

Yes, completely free with no signup required.
