Following the popular features in competitors like Hey (for work) and superhuman I would love the ability to pre-filter spammy people, newsletters or notifications.
This can come in two forms:
  • Mute: Emails automatically archived (so you can still find them back if it actually contained useful stuff)
  • Block: Delete emails/or IMAP block
If it is a simple button that creates a new rule that is fine by me, however copying a sender email and creating the rule manually is too cumbersome.
