I still use my 20 years old hotmail address (OK, I don't really use it anymore... but I still get some mail from newsletters I'm subscribed to), but I read it from thunderbird so I never need to use the ad-ridden web interface.

Then again I would not see the ads anyway. In the case of the tweet we're discussing, I would probably have opted for the "bigger ads" which seems more easily removed by uBlock origin.

You can set mail forwarding from that address. Just have log in couple of times a year so they won't delete the account.
