Trimbox
What it is
Trimbox scans Gmail inboxes for mailing lists and unwanted email, then helps users unsubscribe and clear older messages. Users can unsubscribe from a list with one action; where a formal request is required, Trimbox can send one. It can also remove older messages from a sender in bulk. Deleted mail first goes to Trash and is permanently removed after 30 days. Trimbox creates editable Gmail filters to block unwanted senders. The maker says email data remains on the user’s device and is not shared, and says the service is verified by Google. It also says Gmail access is needed to identify mailing lists and remove unwanted messages. Trimbox is offered as a browser extension, browser use for Gmail, and a mobile app, with Android, iOS, and web listed as platforms. The App Store listing says users can connect unlimited email accounts. The first 10 unsubscribes are free; a subscription unlocks unlimited unsubscribes. Trimbox provides a help center and email support, and says users can request a refund if unsatisfied.
