Love this. Slick. Just for perspective, Alphabet agencies will still tie together all the email accounts with the same handle / custom domain, and even minor variations of such. Heck, so will data brokers. So this isn’t as hidey as some may think. You’re still connecting all your accounts, but requiring a ton of centralization for analysis to be effective. Unfortunately this centralized analysis is a real and present danger.

Example: you order something from Amazon to your home address, using Bitrefill and Amazon@youranondomain.com that you paid for with lightning. FBI and NSA now know your home address, and that all your accounts like stackernews@youranondomain.com and fatsecret@youranondomain.4wrd.cc are yours too.

Remember we’re in the age of capable neural networks and artificial intelligence, where rapid analysis of large datasets is trivial. The difference between 3 different emails and 365 is nothing, if there’s any type of connecting data—in this case the custom domain. Not saying that you must use the custom domain always.

Know what threat you’re trying to mitigate.
