常见问题
What do I enter to get good subject lines?
Describe the email's main topic, who it's going to, and the action you want (open, click, reply). Mentioning any offer, deadline, or hook helps the tool tailor the angles.
What styles of subject line does it generate?
It mixes approaches such as curiosity gaps, urgency and scarcity, benefit-driven statements, questions, and personalised angles, so you get a range rather than variations of one idea.
Will these guarantee a higher open rate?
No tool can guarantee opens; results depend on your list, sender reputation, and timing. The value is generating several testable angles quickly so you can A/B test and learn what your audience responds to.
How long should an email subject line be?
Aim for roughly 30-50 characters so it isn't truncated on mobile inboxes. The tool favours concise lines, but always preview how they render in Gmail and Apple Mail.
Does it consider spam-trigger words?
It leans toward natural, benefit-led phrasing rather than spammy ALL-CAPS or excessive punctuation, which helps deliverability. Still, review lines against your ESP's spam checker before sending.
Can it write the preview text too?
Yes. You can ask for matching preview (preheader) text that complements the subject line instead of repeating it, which together improve the open-rate signal in the inbox.
How many subject lines should I A/B test?
Testing two to three strong, genuinely different angles per send is practical. Generate a batch, pick the most distinct contenders, and let your ESP split-test them on a sample.
Is there a usage limit?
Free use covers 5 generations per day with no signup; each run returns multiple lines. Pro at $19/month gives unlimited generations for high-volume campaign work.
