AI Email Subject Generator

Stop guessing. Use proven templates to write subject lines that get your emails opened.

Low Open Rates?

47% of emails are opened based on the subject line alone. Let's write one that works.

Why Subject Lines are the Most Important Part of Your Email

No matter how great your email content is, it doesn't matter if nobody opens it. The subject line is your one and only chance to make a first impression in an overflowing inbox. Our AI generator uses proven marketing psychology to craft lines that trigger curiosity and urgency.

Strategies for Higher Open Rates

  • Keep it Short: Aim for 40 characters or less to ensure visibility on mobile devices.
  • Personalize: Use names or industry-specific terms to make the reader feel the email was written just for them.
  • Spark Curiosity: Open a "loop" in the reader's mind that can only be closed by reading the email.
  • Limit Emojis: One well-placed emoji can boost engagement, but too many look like spam.

The Spam Folder Watchlist

Modern email providers are incredibly good at filtering out low-quality content. Avoid these common red flags:

  • Excessive use of "FREE," "Act Now," or "Guarantee"
  • Using all capital letters (IT FEELS LIKE SHOUTING)
  • Multiple exclamation points (!!!)
  • Misleading subject lines (don't say "Re:" if it's not a reply)
