Shortwave
For serious individual inbox work, my genuine default recommendation is Superhuman Mail if you use Gmail or Outlook and can justify the premium; for a Gmail-first user who wants the deepest AI workflow, I would choose Shortwave instead.

Spark Mail
Spark Mail — A good cross-provider personal/team client if you want a friendlier, less intense alternative to Superhuman, with Smart Inbox, follow-up tools, team inboxes and drafting, and optional AI that supports more than just Gmail.
