II. The 72 Hours After Registration Are Critical (Key Point)

First 0–24 Hours: What to Do and What Not to Do

Recommended Actions:
• Log in
• Check your inbox
• Send yourself a test email
• Reply to that email
• Stay for a few minutes before logging out

Absolutely Do Not:
• Change your password immediately after registration
• Log in from a different device right after registering
• Bind multiple websites right after registration
• Enable proxies or switch IP addresses back and forth immediately after registration

The only goal during this phase is:
To let Google recognize “This is a normal login + normal email sending and receiving account”
