Sometimes an email sent to me from a known source goes to delete folder. If I recover it from deleted folder in time and respond to that email, my reply now goes to delete folder as well.
See the screenshow below. This is is end of an email sent to me that I recovered and I responded but my response is in deleted folder now and requires to be recovered.

I do have many filters and I checked my name is not in the filter list (that would have caused major problem) as all my outgoing emails would end up in deleted folder which is not the case.
I also checked the sender or their domain is not in the filter (for example kids school emails sometime end up in deleted folder from a certain teacher). How can I fix this issue?
