Branded Return Path (envelope_from) on Shared or Trusted IPs
Description description
Environment
Adobe Marketo Engage
Symptoms
Customers on Shared or Trusted IPs are able to set up additional branding within the Marketo sending infrastructure. You’re 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.
Resolution resolution
Marketo’s default envelope_from (also known as return-path) domains include:
San Jose datacenter - @em-sj-77.mktomail.com
London datacenter - @eu-lon-188.mktomail.com
Ashburn datacenter - @potomac1050.mktomail.com
Sydney datacenter - @snsmtp.mktomail.com
Process:
To implement this, first reach out to your CSM to confirm that branded return path addresses are included in your Marketo package. Branded return path for instances on a Shared IP are a paid addition to your Marketo Subscription.
Then you will need to choose a sub-domain of your choice for this branding, and set up 2 DNS entries depending on which datacenter your Marketo instance is on:
-If your Marketo instance is on the shared or trusted range in San Jose, the configs would be:
IN MX (your subdomain): or.mx.mseme.adobe.net
IN TXT (your subdomain) “v=spf1 include:mktomail.com -all”
-If your Marketo instance is on the shared or trusted range in Ashburn, the configs would be:
IN MX (your subdomain): va.mx.mseme.adobe.net
IN TXT (your subdomain) “v=spf1 include:mktomail.com -all”
-If your Marketo instance is on the shared or trusted range in London, the configs would be:
IN MX (your subdomain): gbr.mx.mseme.adobe.net
IN TXT (your subdomain) “v=spf1 include:mktomail.com -all”
-If your Marketo instance is on the shared or trusted range in Sydney, the configs would be:
IN MX (your subdomain): aus.mx.mseme.adobe.net
IN TXT (your subdomain) “v=spf1 include:mktomail.com -all”
-If your Marketo instance is on the shared or trusted range in Amsterdam, the configs would be:
IN MX (your subdomain): irl.mx.mseme.adobe.net
IN TXT (your subdomain) “v=spf1 include:mktomail.com -all”
Once that DNS setup is completed, submit a case to Adobe Support with those details, and we can complete the process by implementing that branding for your instance’s emails.
