Using pipex legacy account(now part of talktalk) for personal and some work stuff and it works very well either with Thunderbird, webmail or a phone app. Also a Netscape legacy address (now AOL) which works great with Thunderbird and the phone app but is a bit of a pain on the AOL webmail.
Using a googlemail address for some work stuff and it's a pain through webmail and must slower than Netscape-AOL with an email client. Yahoo? Hotmail? Just don't start me. Useless, slow and intrusive.
I have had some email accounts for 13 or 15 years. Many Yahoo users will be familiar with those timescales since that's similar to the time it takes to find the Yahoo email you want and get it to open.
