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.

What does the signal score of 95 mean?
It's how well reviewed Fastmail is, out of 100.
