I have an Apple Watch series 3 and it won't notify me of any emails other than the gmail app . I have tried most other apps even used the stock mail app but no notifications whatsoever come from emails. I had a series 1 and that was fine but the series 3 however doesn't want to know most email apps other than gmail. I wonder if anyone has had the same trouble with email apps and if so how did they go about rectifying it.?
