2nd email account

2nd email account

Currently, I am using the free email.  That one is used for professional and eCommerce (i.e. Amazon) roles.

However, I would like to set up a 2nd Email for personal use (social media).  I tried and it sign up said my phone number is used for my first account.

Do I need to upgrade to have multiple emails to the same number.  It is not an issue because I was think of doing it in the future for other purposes since I am pleased with the service so far
