Adserver.Online uses mail.adsrv.org domain outgoing emails by default. But if you are a premium user, you can set up your own custom email domain via a third-party email delivery service – Mailgun. This is a nice feature used by ad networks and agencies mostly. Alongside with other white-label features, it allows their online businesses to have a more professional and authentic look. Therefore, we highly recommend this feature to ad networks and agencies using our service.
