Use your own custom email address. This thing keeps coming in every few weeks/months.One of the best thing that anyone can do to his online life is to make use of own email addresses. Say you use GSuite to host your custom email address and one fine day google decides to ban you for whatsoever reason, you will be able to switch to any competing service in a flick of few MX records in not more than 5 mins. Ofcourse you have to ensure that you take regular backup of your email accounts.
