Proton Mail, Gmail, Apple Mail, Yahoo Mail, Canary Mail, eM Client, Edison Mail, Fyxer, Clean Email, Unroll.Me, Mailfence, FairEmail, Extra, Wino Mail and Marco are free or have a free plan.

Each listing shows its own date. On this page they run from Oct 4, 2026 to Oct 10, 2026. Vendors change prices and plans without notice, so confirm on their site before you buy.
This page is built from the listings. A tool is here because its listing says so, and each listing names the pages it was read from.
