Yes, you can use your own email address!
ORGs running on Propertybase Package Version's higher than 3.17.34 (1.333) -> how to identify your version, can send multiple emails at once.
You´ll need to have access to your domain server (most probably your IT Administrator has this), as we are needing you to set three CNAME entries:
We recommend to use "em.yourdomain.com". If you would like to see another "subdomain" instead of "em" please let us know. But it does not matter, as it´s never shown to your recipients.
If emails from your Propertybase are marked as SPAM you should consider those settings, too!
Once the CNAMEs are set, please submit us a ticket with your choosen domain. We´ll then validate and activate it.
Depending of your ORG configuration you might use native Salesforce emails, too. Please read here how to enable your domain for those emails as well.
