With the very big caveat that I’m 15 years out of date, you might see if OKCupid or Plenty O Fish are still around.
I would check for you but I’d rather not cause my wife to worry. I met her on OKCupid. If I remember correctly, searching was free but messages always were a paid service regardless of platform.
I have 6 domain renewal notices sitting in my Spam folder now.
Another recent one has been notices supposedly from my email provider saying it’s time to renew. That one almost got me.
I really wish GPG signing of emails had actually taken off. Would have solved this type of problem completely.
