This lightweight Gmail extension ensures your email signature is always correct. "Gmail Signature Reminder" displays a clear message, "Don't forget to set your signature!" right next to the signature selection tool, preventing you from sending emails with the wrong signature.
This should work well for the Chrome Web Store listing! Let me know if you'd like any adjustments. 😊
