A set-and-forget Trimbox alternative
Trimbox is a quick way to unsubscribe from mailing lists and bulk-delete old mail from a sender. Siftbird handles the mail that keeps arriving: it triages every new email on its own, archives clutter instead of deleting it, and costs a flat $5/month.
What Trimbox does
Trimbox is a Gmail unsubscribe tool, best known as a Chrome extension that works inside Gmail, with an iOS app as well. It scans your inbox for mailing lists, lets you unsubscribe from one in a click without opening the email, and can delete every past message from a sender at once to free up storage. Its site says your email data never leaves your device. Your first 10 unsubscribes are free; unlimited use requires a paid subscription sold inside the extension and app.
Why people switch to Siftbird
Trimbox is built around cleanup sessions: you open it, review your lists, pick what to unsubscribe from, and delete what's piled up. That works well for newsletters. It does less for everything else — receipts, shipping updates, account alerts, and notifications from services you still use and can't unsubscribe from. Siftbird makes a call on each new email as it lands, whether or not it came from a mailing list: it leaves important mail unread, marks noise read, and archives clutter. Archived mail stays searchable, nothing is permanently deleted, and any action can be undone in one click.

Where Trimbox may fit better
If your problem is mostly newsletters and a full mailbox, Trimbox is hard to beat for a fast cleanup: your first 10 unsubscribes cost nothing, bulk delete frees storage quickly, and its site says your email data never leaves your device — while Siftbird reads a subject and short snippet on its servers to make each decision. Its mobile app also reportedly supports providers beyond Gmail.
Common questions
How is Siftbird different from Trimbox?
Trimbox helps you find mailing lists, unsubscribe in one click, and bulk-delete past mail from a sender — a cleanup you run when you choose. Siftbird runs continuously: every new email gets a decision (leave it unread, mark it read, or archive it), including mail from senders you can't or don't want to unsubscribe from.
Is Trimbox free?
Partly. Per Trimbox's app listings, your first 10 unsubscribes are free and unlimited unsubscribes need a subscription. Trimbox doesn't publish prices on its website; third-party reviews in 2026 report about $4.99/month or $39.99/year. Verify current terms in the app. Siftbird is a flat $5/month with a 7-day free trial, no card required.
Does Siftbird delete my emails like Trimbox?
No. Siftbird never permanently deletes on its own. By default it archives clutter (still searchable in All Mail) and marks noise read. If you turn on an optional cleanup level, clear junk can go to Trash, where Gmail keeps it recoverable for 30 days. Every action shows up in an activity log with one-click undo.
Can Siftbird unsubscribe me from newsletters?
Yes, in one click when you ask it to. Unsubscribing just isn't its main job. Siftbird's focus is triaging whatever arrives — so the newsletters you keep, and the receipts and alerts you can't opt out of, stop crowding the mail that matters.
