Recently I receive an invitation sent via my gmail. I am interested to abide with such invitation to all my emails in one place. Meaning I could access them in facility. This is probably because cellphone app is in the circulation for putting email facility in one place like Yahoo Mail, Gmail and Outlook. How does it happen? I was confused though with the advanced of technology in the Internet it is not impossible. Woud you be agreeable with this approach or move to get all those emails of your in gateway to access? What would be the possible disadvantage for this?
