Another example of where it pays off to have separate email addresses/aliases for every website/service you use.
Wait, so you literally have hundreds of accounts? How do you manage them all?
This is what I do as well. I purchased my own custom domain name and run aliases off it using Addy. So as an example, an email for an online account would look like:
random9.words@mycustomemail.comThen I feed these accounts into a password manager so I don’t have to remember them.
All the aliases forward mail directly to my main inbox. Companies never see what my real address is. If I get spam, I know which company either sold my data or leaked my data. I can then take action by simply turning off that email alias and then spinning up a new one.
The best thing about owning your custom domain is that you’re in control and never have to change your email addresses. If I want to move to a new email provider, I can easily do that. The process, simplified:
Edit: All providers make it very simple to set up a custom domain. If you can follow instructions and copy and paste text, their systems will run checks to make sure you did it correctly and it’s syncing properly. Very easy for those who aren’t technical.
wouldn't profilers simply track via the domain tld instead of the whole address...shopping1 at uniquedomain, bank2 at uniquedomain , etc
and in the case of aliasing, couldnt a domain provider tell where the aliases rout to and sell that info as a side earner?
Great questions! Seriously, those made me think for sure.
For question one, I suppose a profiler could do that. If my domain name is myemaildomain.com, they probably could track all emails and sell it collectively. But I don’t think corporations do that at this time. That would be akin to profiling all Hotmail, Gmail, Live, etc emails, appreciating those are massive services. I suppose if nefarious actors were to do that to my domain, I could consider switching domains - I have multiple domain names I own, and it’d be trivial to use the other ones. In the years I’ve been using a custom domain for email, I haven’t encountered any nefarious actors and have significantly eliminated any spam.
For question two, the domain provider I use doesn’t do that in their terms of service. However, if they did look at my MX records and decided they wanted to profile me as a user of Addy, they definitely could do that. Though it would hurt their business as many users would migrate their domains to new registrars - I certainly would move my domains to a new registrar!
