Good thinking!

I highly recommend getting your own domain name! Then you can setup google workspaces, or fastmail, or proton mail, or tutanota with the domain name and have all email to that domain go to your one inbox.

Fast mail has a nice feature where if you reply to a email X@domain.example the from address for your message will be X@domain.example automatically!

This allows you to have infinite address for services, and you can block an address that gets spammed or breached. If you want to be extra spicy setup a second level domain to avoid any automatic bot spam to the top level domain. i.e. AmazonLogin@service.domain.example.

My workflow is ServiceName@type.domain.example, then I can sort all email by ServiceName on the To line. Really helps reduce spam. So far I’ve only had a data breach with Xfinity, so I’m on Xfinity3@type.domain.example with xfinity and xfinity1 both blocked.

I use aliases through a third party (DDG E-mail Protection) everywhere except with my banking, my government and my health services. And even on those, I don’t give the primary e-mail adress. Since I have a custom domain, I create one alias for each (banking@customdomain.com, health@customdomain.com, gov@customdomain.com).

For the most part yes. The account I’m posting from now is relatively identifiable but I will probably switch to a more anonymous one with an anonymous email at some point.

I use masked emails for everything. Either thru fastmail.com or the proton.me one

Everything I run through simplelogin with proton unlimited. Don’t give out my real email to anyone unless it’s someone I know irl

Austici if a free email service that allows for 5 aliases at a time, but at anytime time you can remove one and create a new alias.

100% of all email addresses I give out are an alias to my Austici account.

For Amazon, I use alonger alias address that I create when I order something so I get the email notices about my order, then after I get my order I delete the alias so all Amazon emils bounce back because if I didn’t order something, there is no reason for Amazon to email me.

I have two domain names. One goes to anonaddy and I use that for all non-important stuff. Maillinglists (for discount), orders on a sketchy site, signingup for social media.
The other ends up at protonmail and is for more serious stuff I don’t want to route via anonaddy (while I trust the developer and the service, I just want extra safety). I use aliases at protonmail as well to know where stuff comes from.

Deciding which domain to use depends on a couple of things:

• what happens if they access my mail. Is there a payment option connected, can they get into other services or request stuff from the government? If yes, chances are I go with the proton route.
• do I expect a lot of advertisement, selling of my data or security breaches? If yes, I go with the anonaddy route.

For amazon I use the anonaddy route. I do not add my creditcard or bank account to my account and if they do gain access, they will only get my email.

Hope this helps.
