Setting up an Envelope Domain

It's important to set up an email marketing sub-domain (eg., mailer.company.com) with required security settings.

The Envelope Domain is not the same as the Email From address. Instead, it is used for message routing and appears in the header of the email:
clipboard_e4ad014cddf26718f1b4d9691c1f916b0.png

This domain must be specially set up for this purpose, which is a one-time process per Act-On account.

You must enable Sender Policy Framework (SPF) for this domain to let Act-On send emails on your behalf.

Work with your mail or IT team to:

  1. Create the sub-domain (eg., mailer.company.com) for your email envelope
    • If you have multiple domains, choose the one with the healthiest email reputation
  2. Create two new records under the DNS of this sub-domain:
    1. TXT record:
      v=spf1 include:_spf.act-on.net -all
    2. MX record that points to:
      est-mta.b2b-mail.net (priority 10)
  3. Continue the process below

Important: Setup is not finished until all steps below are complete.
