Removing Mail (completely) from my Apple Watch.

I use my Apple Watch for only a few main things: telling time, notifications, Siri functionality, Messages, and the activity. Aside from getting notifications about email I receive from VIPs that I get notifications on from my phone, I don’t use my watch to read or compose mail whatsoever. Mail is taking 1.6gb of space on my watch, and I don’t want it really taking up any. How do I remove mail and keep it super small but not lose notifications that I get? It’s getting in the way of me being able to do software updates because it’s taking half of my storage space unnecessarily.

thank you!
