What are the benefits of using those sites?
I’ve heard Yahoo! is good for stock market trading and financial news, but haven’t heard anything else about any of them.
Yahoo brought the company that hosted my email back then when they had plenty of money, and I never had a reason to stop using it.
I also have a gmail, that is completely unusable compared to it. And an email in a domain registered to me. But from those 3, the only one I don’t use regularly is the gmail.
