SEO has essentially destroyed search engines, what are some very useful websites that you might not get given by Google?
you can also just buy your own domain and set it up your gmail/whatever as the catchall, then use appname@mydomain.com
Last I saw, Google charges for this. More than this guy’s service.
Also, it seems like his service is about automatically having username-category email addresses. Definitely not hard to replicate, but it circumvents the common blocking of plus-signs in email addresses you see nowadays. And while not hard, it’s a bit less trivial to catch any old email with a dash in it and “magically” convert it to a category in the main inbox.
Google doesn’t even factor into this. Go to your registrar of choice (namecheap, etc), buy a domain, and setup that domain to forward all emails to your email address.
So if you have abraxas@gmail.com and you just bought abraxas.me, in namecheap you can setup *@abraxas.me to go to your gmail account, and then sign up for sites using whatever@abraxas.me you want. There’s no + or - involved, use any word you want. Signing up for lemmy.world? lemmyworld@abraxas.me will go right to your gmail (or whatever email you use)
Are you able to differentiate between emails as they come in? E.g., seeing an email was sent to lemmyworld@abraxas.me vs spammynewsletter@abracas.me?
