How to use Zoho Campaign service with existing zoho mail account

Namaste.

We wish to use Zoho Campaign paid service for the account  vivekanandahouse(at)chennaimath(dot)in. Currently we configured zoho in gmail and using it for sending bulk messages. We don't want our above said account to get locked due to bounce limit.

Please let us know the process how to use above email account for Zoho Campaign. Provide the required information.
Early response would be appreciated.
