Senttri vs. Gmail's tabs

Gmail's tabs are free but only ever sort a single Gmail account into five fixed categories you can't customize. Senttri unifies Gmail, Outlook, Yahoo, iCloud, and Microsoft 365 into one inbox with AI-defined categories. Gmail's Gmailify bridge — the one feature that partly extended tabs-like sorting to other providers — is being discontinued entirely by January 2027.

Gmail's tabs (Primary, Social, Promotions, Updates, Forums) are free, and for a single Gmail account, they do a reasonable job of separating obvious bulk mail from everything else. Two real limits worth knowing: you can't define your own categories — only turn Google's five fixed ones on or off — and the sorting only ever applies to that one Gmail account.

That second point is the whole comparison, honestly. Gmail did have a bridge feature (Gmailify) that could apply some Gmail behavior to a linked Yahoo, Outlook.com, or AOL account — Google is discontinuing it entirely by January 2027. Once that happens, there will be no way to get Gmail-style sorting applied to a non-Gmail account at all. If you only ever use Gmail, its tabs are free and fine. If you also have a work Microsoft 365 account, an old Yahoo address, or an iCloud inbox, Gmail's tabs simply don't reach them — which is the exact gap Senttri exists to close.

Comparison verified July 16, 2026 against Google's official Gmail Help and Workspace documentation, including Google's own Gmailify discontinuation notice for the January 2027 date above. Gmail's own features change over time — see Google's current help article for the latest. If anything here is out of date, let us know.
