My personal tip, use a brand new email for every new website you need to create an account with, if they require an email address. You can easily make one even using gmail and any old android phone.
I can't imagine how many emails you need, especially if you are an active person in online world

I feel I don''t need it all because when our passwords change, we are the first to get notofications via email and if that happens the next step is to immediately change the password.
Account an exchange or an email easy to hack then it indicates that we are not enough to secure these accounts with additional security such as authy or anykind of seurity.
