    DKIM entry


    I have just received feedback from a client that the newsletter has been classified as a possible SPAN.

    When testing the email on I get a result of 8.9/10 which is pretty good. Probably the customer's SPAM filter is set very sensitively.

    The email gets a point deduction because no DKIM entry was set. A conversation with my provider revealed that our emails are sent via a newsletter gateway that is not directly linked to a domain. Therefore, no DKIM entry can be set on their side. However, I was told that some newsletter programmes have the possibility to set DKIM entries.

    Therefore my question: Is it possible to set a DKIM entry in Newsletter Studio?

    Thank you

    Kind regards, Edi

    So SPAM detection is an art in it self but it has two basic parts.

    The email content This is probably what you've tested with and this is also the only part that is in the control of the package.

    The sending server and domain Depending on how you're sending the e-mail one needs to configure things correctly.

    Let's say that we're sending e-mail with a sender e-mail [email protected] using a SMTP-server from SendGrid.

    In this case we need to configure some DNS-records on to allow SendGrid to "send on behalf of" this domain. This is called SPF (Sender Policy Framework), it's also good to configure DKIM which is a public/private key used to validate that the email content really comes from the sending server.

    All this configuration is an infrastructure concern that the package has no control over. You need to check with your SMTP provider (or whatever service you're using to send with) and make sure that the domain for e-mail used as "Sender" when sending emails has the right configuration. If your provider can't set DKIM when sending the emails I would consider looking at some other provider like SendGrid, SendInBlue, MailGun or so.

    All the best!

    Hi Markus,

    thanks for the explanation. I will ask around and consider switching to another provider.

    Best regards, Edi
