Interestingly Fastmail have also allowed subdomains in addition to name+blah@domain.com routing, to make it harder to guess your "real" email. So you can sign up for new companies with random@someservice.mydomain.com and have it still route into our inbox. https://www.fastmail.help/hc/en-us/articles/360060591053-Plus-addressing-and-subdomain-addressing https://www.fastmail.help/hc/en-us/articles/360060591053-Plu... I've done this a bunch in past, but wish it was easier to go back and change existing services. Also found a couple that reject sign-ups when their name is in the username part. As a user of both 1Pass and Fastmail for years, this is a really neat addition. Next I'd love 1Pass to generate random phone numbers to use that I can recall quickly for things like supermarket checkout where I need to enter a number to get their discounts, and I don't want to use my real one. Doesn't even need to be a genuine phone line, just a 10 digit code.

Kroger, at least, let's you change your "alternate ID" to any 10 digit number that isn't used by someone else. Just log in to the web site and change it.

My personal solution to this problem was: * register a pseudonymous domain and use Fastmail to forward it in to my real email * use Twilio + a little TwiML to register a real phone number in my area code & have all messages/calls forward to my cell This let me establish trust domains: when I share my email with an untrusted entity they get companyname@mypseudonym.com & the phone number I registered before. I always have the ability to know where the communications come from & can quickly cut off junk/spam at either source[1]. And if a company is trustworthy I could always move them to my real domain/phone if I so wanted. [1]: Phone is obviously harder as there's only one number, but legitimate companies seldom if ever call – their junk is from a consistent text source that's easier to block. My burner & my clean numbers get about the same amount of autodialer calls, sadly.

  I've also found many, many companies that blacklist several keywords including "spam" (before using unique emails for all services I used spam@mydomain.com for most sign ups).
