Yahoo email is horrible and they're not listening to the feedback!
Yahoo mail is doing just too much and it's horrible. When signing in to access your free Yahoo email, now you have to have a code sent to your phone or to an alternate email to get your email. I understand the need for security, but this is just too much! You are showing way too many ads and $35 a month for mail pro is just ridiculous. Slowly but surely, I'll be leaving Yahoo because you're not listening to feedback which shows Yahoo doesn't care about their users.

If there’s something unusual about your sign in or recent activity, we’ll ask you to go through another verification step after you’ve entered the correct password. This helps protect your account from unauthorized access. You may be prompted to get a verification code on your Yahoo app, recovery phone number, or recovery email address for any of the following reasons: https://help.yahoo.com/kb/SLN8923.html
