Email services create a digital envelope for each email message to use for routing and delivery. You must have an email marketing sub-domain (eg., mailer.company.com) specifically configured for your message envelopes.
Just like with physical mail, the Envelope Domain address is on the envelope only – it is separate from the Email From address that appears on the message itself.
This process should be completed when first setting up your Act-On account. Once set, it does not need to be configured again.
SPF for Envelope Domain
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:
- 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
- Create two new records under the DNS of this sub-domain:
- TXT record:
v=spf1 include:_spf.act-on.net -all
- MX record that points to:
est-mta.b2b-mail.net (priority 10)
- TXT record:
- Continue the process below
Important: Setup is not finished until all steps below are complete.
