Your prompt
I need some subject line options for an email. Here's what the email is about: inviting past customers to a summer sale with 20% off It's going to existing customers / my team / a hiring manager, and I want it to feel friendly and clear. The main thing I want them to do or know is click through and shop / reply by Friday / feel welcomed. Please give me eight subject line options with a mix of angles: some clear and direct, some more curious, and a couple shorter ones. Keep them honest, avoid clickbait, and note which one you'd pick and why.
Tips
The subject line only needs to earn the open, so keep it honest about what is inside, because a subject that oversells leaves readers annoyed and less likely to open the next one. On a phone, only the first few words show, so ask the AI for a few options that front-load the most important word.
What a good result looks like
Eight subject line options spanning direct, curious, and short styles, all honest rather than clickbait, plus a note on which one to pick and why.
