Several years ago one of my free-mail accounts was wiped due to inactivity. I don't think I lost anything important, but it was a bit of a hassle. After that I setup a few recurring calendar events with links to the various service's login URLs. Then every 6 months-1 year I'd simply click the link in my reminder and keep the account active.
