Tags

Tags are colored labels you can apply to threads to group them - “needs reply”, “billing”, “travel”, whatever fits your workflow. Tags live inside SuperMail only: they don’t round-trip to Gmail labels, Outlook categories, or IMAP keywords. A tag you apply here is visible here; the same thread in your native Gmail or Outlook client looks unchanged.

Creating a tag

• From a thread: open the thread, click the tag picker in the toolbar, type a new name, and pick a color.
• From settings: Settings → Tags → New lets you create tags up front (useful for setting up a color system before you start labelling).

Tag names can include spaces, but prefer hyphens for search friendliness (needs-reply over needs reply).

What tags are not

• They are not Gmail labels. Renaming or deleting a tag in SuperMail does not touch any label on Gmail’s side, and vice versa.
• They are not Outlook categories or IMAP keywords. We don’t read them from the server and don’t write them back.
• They are not the same as folders. Tags are additive; a thread can have many tags and still live in the inbox.

If you want a behaviour that does sync back to the provider - star, archive, delete, mark read - use those actions instead. Those map to real flags / folders that providers understand:

• Star maps to the provider’s starred / flagged flag (\Flagged over IMAP).
• Archive moves the message out of the inbox folder.
• Delete moves the message to the provider’s Trash.
• Mark read / unread maps to the IMAP \Seen flag.

Auto-tagging with rules

Settings → Rules → New lets you turn a search query into an auto-tagger. Example: “any new message with from contains @stripe.com gets tagged billing and skips the inbox”.

When you save a new rule, SuperMail asks if you want to apply it to existing matching messages as well as future ones - useful for backfilling a tag across mail you’ve already received.
