I've been a happy Fastmail customer for years prior to working on this feature. I've used a wildcard with my Fastmail account, created a new email address for each service I sign up with, and stored that email address in 1Password. All by hand. It's a tiny hassle, but one that I think is worth it.

The Masked Email integration makes that entire process automatic. It's even easier than before. It's enough to convince a few Fastmail-using friends to start doing it.
