Answer 1

Bring your RAM closer to the volume of letters, upgrade the percentage - then everything will fly
away / move attachments to letters
// or delete the archive that you do not use

Answer 2

Yes, there are no such mail clients, no one is guided by many letters and boxes. Simply because there are only a few people like you, not even a few percent of just a few.
