Enabling authentication for your domain

In general, Direct Mail handles email authentication for you automatically when you send using our e3 Delivery Service. You are not required to edit any DNS settings for your domain name.

If you would like to authenticate your outbound emails using your own domain name, then please follow the guides below.

Sender ID

If you would like e3 Delivery Service to enable Sender ID for your emails, you may do so. Please edit the DNS TXT record for your domain to include SPF records for e3 Delivery Service email servers. This is done by adding include:userinclude.dme3ds1.com to any existing SPF record you may already have. If you don't have an existing SPF record, set your DNS TXT record to "v=spf1 include:userinclude.dme3ds1.com ?all"

DKIM

If you would like e3 Delivery Service to use your own domain name to sign emails, please:

  • Enable Sender ID by following the instructions above, then
  • Contact Direct Mail support to obtain the correct DNS settings to enable this feature.

Supporting Your DMARC Policy

If your domain has a DMARC policy that requires SPF or DKIM conformance, you can configure Direct Mail to conform with your policies. Here's how:

  • SPF/Sender ID: Edit the DNS TXT record for your domain to include SPF records for e3 Delivery Service email servers. This is done by adding include:userinclude.dme3ds1.com to any existing SPF record you may already have. If you don't have an existing SPF record, set your DNS TXT record to "v=spf1 include:userinclude.dme3ds1.com ?all"
  • DKIM. Direct Mail can sign on behalf of your domain. Please contact Direct Mail support to obtain the correct DNS settings to enable this feature.
