I am currently a Simplelogin + ProtonMail user.
Since I use the free Simplelogin, I get a limited ammount of aliases. So my logic is:
firstname.lastname@example.org -> gaming email@example.com -> coding-related platforms firstname.lastname@example.org -> bank, paypal and related
You get the logic. But I have found 3 websites I needed to have an account and couldnt, because the email is “suspicious / temporary”
By using my own domain name (which I already own btw), I could theoretically have infinite aliases, one per account. So it’s even better separated.
Besides that, I believe I would also not be flagged by websites, since the domain wont be shared for thousands of users.
Here are (what I believe to be) cons:
Single domain name, people will be able to trace the emails to a single user across all aliases?
To buy my domains, I had to fill my real name and adress. My provider offers WHOIS privacy, but is it enough?
What do you guys think?
