My opinion disagrees with others. I have recommended to all my customers to get away from Yahoo mail. In the past, Yahoo has had less security on their end to prevent major breaches than any other email provider. They just didn't seem to care that much about it at the time of the first big breach and let it drag on for years without action resulting in more breaches.
One of their data breaches is one of the worst and most infamous cases of a known cyberattack and currently holds the record for the most people affected. Unless it's been settled there is a major class action suit going on now.The first attack occurred in 2013, and many more would continue over the next three years. They finally got better and at least offered 2-step verification, but who wants to have to enter a code every time he reads his e-mail in order to feel secure. IMO they are still not up to par with some of the other email providers.
As far as spam, it has become a fact of life no matter what email provider. You can help it, but you can't stop it. Make your password as difficult as you can no matter what provider you use. Mine is 22 characters long, lower and upper case, numbers, and several symbols. I am very careful who has my email. I use a throw-away email for any site that requires it except places like my finances, Amazon, this forum, etc.
