Configuring vRO to send emails for gmail


Google allows you to relay up to 2000 emails per rolling 24 hour period, which can be useful for development of workflows via vRO. The steps below are written for standard gmail accounts. If you have a G Suite account then the steps are subtly different in that the SMTP host name is ‘’ and not ‘’. The message per day limit is also increased when using a G Suite account is that you can send up to 10000 messages per rolling 24 hour period. Lastly, when using vRO with a G Suite account security needs to be relaxed within G Suite to permit sending emails from less secure apps.
