Tell HN: Gmail's spam filters have gone bonkers

I don't know what is happening with Gmail but lately Gmail's aggressive spam filtering created a huge problem for me.

It was a reply I sent to an email yet Gmail somehow figured out it was spam and the other person never got it (which I learned after 1 week)

Two weeks before they sent the property tax notice (from the govt) in spam and had I missed that email there would have been a penalty.

This is a very old Gmail address almost 10 years or more so I don't know what's happening but I've stopped trusting Gmail altogether after this.

This spam thing is such a black box, so don't be like me and check your spam folder just like you check your inbox if you're on Gmail.

P.S. Also looking for a good alternative to gmail if anybody has some suggestions. Right now I've just created a filter to send all email to inbox.
