I use Fastmail and 1Password, and I do used the masked email functionality. There is a massive gap, though, that makes it very difficult to rely on masked email. When I sign up for a new account somewhere, I can choose to create a masked email. If I later need to email that company (not reply via an existing email message), I must first somehow look up what email I used for that company, go into fastmail settings and create a "sender identity", remember the email address again, and then when I compose, remember to choose the sender identity that is associated with the masked email address I created for that specific company. If I forget or mess up any of those steps, I end up sending from my primary account or some other masked email address associated with some other company. Multiply that by dozens or even a hundred companies!
It would be really nice if adding a masked email automatically created a "sending identity." Further, it would be nice if the masked email account had a nickname that included the domain I was on when I created the account. That way if I need to send an email to [email protected], I can use the filter and type "nike.com" and get the correct masked email address.
