I have a main Google account and two other email addresses I'd like to manage through the main account. One is a another Gmail address and the other is a @outlook address.
I understand that I have two options: 1. Use Gmailify (possible for one email address only) 2. Forward each email address to the main one and add them as "Send mail as", so that I can send emails from them too.
Obviously, if I were to choose option 1 for one address, I'd have to choose 2 for the other as only one other email address can be "Gmailified".
Is there any important difference between the two options (or any difference at all)?
