I have also like quite some domains.

One just firstnamelastname to have it

One for homelabbing

One for business

One, because I thought firstname@lastname.email was a cool idea. Now all my accounts run through it and I cannot change it anymore :/

One for my old startup, where I just like the name to much

One for another old business, but my mailserver runs through that domain, and it is too much of a bother to change that 😅

So, remember folks: don’t buy too many domains, it becomes a liability.
