I really like MailMate. As described by the developer:
MailMate is not the most widespread, the cheapest, or the greatest looking email client, but I also have no aspiration to MailMate ever being any of these. Instead, MailMate aspires to be the most powerful, the most flexible, the most efficient, the most standards compliant, and the most secure email client.
Ticks all the boxes for me. It has great search functionality, supports Markdown, and I can create emails in a text editor of my choice which can be pretty handy sometimes.

MailMate is amazing once you have it setup correctly.
