In general, every Engage system has one or more domains which it can use for sendout. These domains are entered and authorized for sendout when the system is set up. Authorization is achieved by registering the Engage IP address in the Domain Name System (DNS).

Domain verification refers to the part of the address after the @ sign.

It is possible to send with any address before the @ sign. For example, if your sendout system uses the domain, the addresses you can send with include, but are not limited to, all of the following:


However, if you sendout with the address (that is, if you remove "news" from the domain), the domain does not have official permission to send the message.

Domain verification in Engage​

Domain verification is performed automatically by Engage when a new ​Sender Address​ is entered in the group settings (see ​Reply Handling (tab)​). The system checks that the domain used for the sendout is verified. Specifically, it checks whether the address entered corresponds to the published Resource Record. If the address is not authorized for sendout, a warning message is automatically displayed on the interface. The warning message appears as an orange triangle next to the email input field in the group settings and as a status message during the sendout process.

To ensure delivery, all email messages must be sent from domain(s) that are registered for your Engage system. This allows the Internet Service Providers (ISPs) to clearly identify you as the sender and ensures optimal secure delivery.

To authorize additional domains for sendout, contact your customer service representative.

Or enter a new email address in the group settings that uses one of the domain(s) registered for your Engage system.

Customizing address data in Engage​

In the group settings of Engage, it is possible to edit sender addresses, (see ​Reply Handling (tab)​).

However, as shown above, this does not guarantee that a sendout automatically takes place using a verified address.

In order to avoid having your email classified as spam, it is important to always send with a verified email address. This can be achieved in two ways:

  1. Customize the sender address: Change the sender address in your group settings so that it corresponds to the domain of the sendout system.
  2. Resource record: Insert the following code in the DNS field of your domain (the domain used for sendout) " v=spf1 ip4: ip4: ~all ". In this case, you authorize the domains of the sender address for sendout and can continue to use the altered sendout domains.
