升级至 Pro — $19/moYour 邮件主题生成器 results will appear here
Expect copy that's ready to send — subject line options, body, CTA, and tone variations.
A/B test subject lines for weekly newsletter sends to boost open rates
Generate launch-day email subject lines for a new product or feature release
Re-engage dormant subscribers with curiosity-driven win-back subject lines
Create subject line swipe files for recurring campaign types (promos, digests, announcements)
Start with 10. Pick the top 2 for an A/B test, and keep the rest in a swipe file for future sends. If you run multivariate tests (Mailchimp, Klaviyo), go with 15.
Each line is scored for spam risk, and the tool flags trigger words. However, deliverability also depends on your sender reputation, list hygiene, and ESP. Always run a test send.
Under 50 characters for maximum mobile visibility. The tool shows character counts for every line so you can prioritize short options.
Yes — select 'Get Replies' as your goal and the AI will favor conversational, low-hype subject lines that perform better in cold email.
Preview text (preheader) appears after the subject line in most email clients. The tool generates complementary preview text that extends the hook without repeating the subject, boosting open rates.
The AI uses emojis strategically where data shows they improve opens. Each variation is labeled with the technique used, so you can easily filter emoji vs. plain-text lines.
