Fastmail

Fastmail is a privacy-oriented email hosting service with custom domain support, calendars, contacts, and robust spam filtering. A user-friendly web interface and mobile apps ensure easy access. Its advanced rules engine sorts messages into folders, auto-replies, or forwards. Unlike free ad-supported inboxes, Fastmail does not scan messages for ad purposes. The platform supports masks/aliases to help protect the primary address. For small teams, shared calendars and contact lists streamline collaboration. Fastmail suits users who want a simpler, ad-free, privacy-focused email experience with powerful features under the hood.
