Deliverability question / gmail interpretation of from email

Denise_Greenbe7 · ‎06-03-2019

When our emails arrive in my client's company gmail email accounts, the company "from email address" that we set in Marketo is ignored and instead gmail displays this:

Is the part underlined in red specific to our company? Or does it just mean the real sender is Marketo - or a particular shared Marketo IP? I'm asking because I've seen that same email address reported as spam in bounce/email suspend causes. We're wondering if we should look into getting a dedicated IP address to lessen instances of being interpreted as spam. In other words, if a filter decides that potomac1050.mktomail.com is a spammer is that a response to my client's company or to a Marketo shared IP address?

It's signed by the client domain (as well as by Marketo) as expected.

And the 'via' as it turns out, doesn't show up, in general consumer Gmail.

Thus far, this looks to be due to them testing with their own (GSuite-hosted) domain and Gmail being more vigilant in that special case, even though there's no undue impersonation.

SPF doesn't have any relevance to a Marketo instance without a branded envelope sender. The SPF record for your domain will never be queried if it isn't used in the SMTP envelope.
