Gmail filter setup

Gmail filter setup: actions, labels, and existing mail.

After you choose filter criteria, Gmail can label, archive, categorize, mark important, forward, delete, or apply the rule to matching conversations.

KeepKnown moving unknown Gmail senders into a separate label

Gmail filter setup has two parts: choose criteria, then choose actions. Actions include Apply label, Skip Inbox, Categorize as, Mark as important, forward, delete, star, and apply the filter to existing conversations.

Short answer

Choose filter actions after the search criteria match.

Use Gmail filter actions for known senders, subjects, words, labels, and categories. Use KeepKnown when the rule depends on whether the sender is already in your contacts.

Gmail filter actions to check

  1. Apply a label when matching messages need a stable folder-like view.
  2. Skip Inbox when messages should be archived automatically.
  3. Categorize as when Gmail should send matching mail to a tab.
  4. Mark as important or star when known mail needs visibility.
  5. Apply the filter to matching conversations when old mail should be cleaned too.
