Branded Return Path (envelope_from) on Dedicated IPs

Issue

Customers on Dedicated IPs are able to set up additional branding within the Marketo sending infrastructure.  You are able to set up a branded 'envelope_from' so the From Domain used by the Marketo sending servers is associated with your brand instead of with Marketo.

This enables you to further isolate your sending reputation to your own brand and email activity.  This can improve delivery rates to email networks looking for this level of alignment (generally smaller B2B domains but this can also help with AOL and Gmail).  Branded 'envelope_from' is also key for authentication using DMARC, as it will allow you to align the domains in your email headers.


Solution

Marketo's default return path/envelope_from domains include:

San Jose datacenter - @em-2-sj-77.mktomail.com

London datacenter -    @eu-lon-188.mktomail.com

Ashburn datacenter - @potomac1050.mktomail.com

Sydney datacenter -  @snsmtp.mktomail.com

 

Examples:

  • Standard:
    • Dedicated IP 199.15.21x.xxx
    • envelope_from: em-sj-77.mktomail.com

 

  • Branded:
    • Dedicated IP 199.15.21x.xxx
    • envelope_from: m01.companydomain.com

 

Process:

To implement this, you will need to chose a sub-domain of your choice for this branding, and set up 3 DNS entries:

  • IN A (your sub-domain): Your dedicated IP
  • IN MX (your sub-domain): Your dedicated IP's host-name (a sub-domain of mktdns.com)
  • IN TXT (your sub-domain) “v=spf1 a mx include:mktomail.com ~all”

 

The subdomain must be unique. You cannot use your landing page or tracking link domains for your branded return path.  Once that DNS setup is completed, submit a case to Marketo Support with those details and we can complete the process by implementing that branding for your instance's emails.

    @Bob Goman​ and @Roxann McGlumphy​  I am very intrigued by this article and another concerning branded envelopes to help improve deliverability. I have a scenario that I would love your comment on.

    In my instance I have now 4 separate domains setup with SPF and DKIM host records. One of the domains was used prior to the DKIM DNS was properly setup and verified. The client of this domain found out that their contacts did not receive a recent campaign and it was discovered to be going directly to a spam folder. The client has sense requested that we go back to their previous email marketing provider that seems to have passed through with no issues.

    My hope is by using your recommendations above that my client could be use this method and potentially disassociate their previous send with the contacts email server.

    My instance is on a dedicated domain.

    The struggle I may have is the ability to easily communicate this to the IT group within my company that will need to update my domains.

    Any thoughts?

    Hello Eric,

    Branded envelope may or my not help your client avoid the spam folder.  It depends on the reason(s) the email is going to spam in the first place, which is something we can't know from the outside. You could certainly try it.

    Thanks for your reply! I will plan to test with the clients domain and let you know if anything changes.
