Has used Fastmail with their own domains for about 15 months. Finds the support very good and human, and likes the configurability even though the many settings felt overwhelming at first, plus the detailed headers, boolean search and subdomain aliasing.

A score out of 100. Negative and mixed reviews take points off, and so does having only a few reviews, so a handful of glowing reviews can’t beat a product many people like.

Easy migration from Gmail or Google Workspace and human support, though the calendar feels clunky.
