I built MsgMaster, an AI inbox that declutters email using intent + calendar context

Hey Product Hunt 👋

I’m Isaac, and I’m building MsgMaster.ca, an AI-powered email tool designed to help busy founders and operators regain control of their inbox.

Most email tools rely on rules, labels, and manual sorting. MsgMaster takes a different approach by:

• Sorting emails by intent (action required vs. noise)

• Understanding calendar context (meetings, scheduling, follow-ups)

• Reducing inbox clutter without constant manual cleanup

The goal is simple: spend less time managing email and more time doing actual work.

MsgMaster is live and offering 45% off until March 1, with a free trial available. I’d love feedback from the PH community, especially from anyone drowning in email or building productivity tools themselves.

Happy to answer questions or share how we’re building it.

Any feedback, good or bad, would be appreciated!!
