Newsletter Digest

Bulk mail is read in aggregate or not at all. Produce one digest the user can skim in under a minute, then clear the folder.

• Gather by shape, not by guess: search_messages over the provider's bulk categories and unsubscribe-bearing senders.
• Summarise per source, one line covering everything they sent — five messages from one sender become one line.
• Pull out what is actually actionable (a dated event, an expiring notice, a receipt) and name it separately. That is not digest material.
• Then archive_message_batch; label first if the user wants them findable.

Report the count and window ("18 newsletters since Monday"), the per-source lines oldest-first, then the actionable items and what you archived.

More than a dozen lines is a list, not a digest — group harder. Never delete bulk mail and never unsubscribe on the user's behalf.
