I own a .net domain but recently I was able to get the domain that I originally wanted to own. I wanted move over to the new domain for my email which was the only thing I was using my .net domain for.
I only had two email under that .net domain which is just for looking for work and my personal for “buying” games.
What are the ramifications of letting someone else own my domain in the future? (Mostly talking about email)
You can’t receive those emails anymore.
Someone else can.
When I opened my business there was a company that made Android apps that had the same name. They since closed and I own the domain. I still get their Facebook and play store emails. I have tried to stop emails from both but that appears to be impossible.
Recover the accounts and close them?
The Google account’s recovery is tied to a phone number, and the Facebook account wanted me to identify pictures or ask friends for help.
I was not trying to take over those accounts, merely stop all of the emails. I have contacted both Google and Facebook about it and have done nothing in 5+ years.
Might be illegal
If the company is gone now then, I guess it would harm whoever bought the rights to the apps or the name? In which case they can contact that entity to sort it out
