Browser extensionfree

MailSenseAI is a free Gmail sidebar that shows real-time open, click and reply signals for sent emails, without adding a visible tracking footer. It weighs engagement across opens, clicks and replies over 72 hours and drafts a follow-up when a thread goes warm. It's positioned as a cleaner, privacy-minded alternative to trackers like Mailtrack and Mailsuite for anyone who follows up on email regularly.
