CONGRATS! Now you have a G Suite account. There are still a few things left to do.
G Suite is going to ask for your username and password to change the MX Records with the DNS settings in GoDaddy.com. (Assuming you purchased your domain through GoDaddy.com) You can watch the tutorial above.
If you provide your username and password and click the allow button, it will do this for you.
If you don’t want to allow G Suite to access your account, you can go in manually to GoDaddy and add the MX records yourself.
Once you’ve updated the MX records within your DNS settings, it will point your G Suite email to your domain name. Once that is verified, you will be able to login to your G Suite email and start sending emails.
