MailBoom cleans a messy Gmail inbox—fast, safe, and private. Separate newsletters from real mail, preview exactly what will change, then archive in bulk with one tap. What it does • Find lists instantly: Detects newsletters/mailing lists via email headers (List-Id, List-Unsubscribe). • Smart selection: Include/exclude senders, choose All / Lists / Non-Lists, and filter by age with a simple slider. • One-tap summaries: Tap the brain icon to scan recent subjects + timestamps for a sender, then open the full message if needed. • Optional Unsubscribe: Uses List-Unsubscribe (including One-Click where available) from the most recent email per list sender. • Accurate preview: See exact counts before you archive—no surprises. • Per-account presets: Save, apply, and set a default preset for each signed-in Gmail account. • Safe archiving: Removes the INBOX label only; messages are not deleted and remain searchable in All Mail. • Private by design: Processing runs on-device; the app makes only the Gmail API calls needed to perform your actions.
