Sendgrid Domain Authentication Issues

In some cases, we are using the Wix email compatibilities, which are handled by Sendmail. We also sent up our own Sendgrid account and our connecting directing via Sendmail’s API to allow us to customize our emails for other scenarios.

For the most part, everything is working fine, except for Microsoft Outlook, which are not being received by the recipients using Outlook. We researched the issue and found we should modify our CNAME records to resolve the issue: How to set up domain authentication | Twilio

However, our Wix CNAME records already have records associated to sendmail, I’m guessing for domain authentication.

For example: s1._domainkey.somedomain.com

To use the Sendmail API, we are being told to have a different entry for s1._domainkey.somedomain.com.

How do we resolve?

Thanks!

You’re not routing your API key properly to your backend module, you’ll need to double check and authenticate your domain keys. Then it should work.

Again, everything works and it works with most email services. However, there is an issue with Outlook mail services.

To further explain the issue, see: Using SendGrid and emails are not being delivered to Hotmail/Outlook/Live/MSN.com recipients? - JosephGuadagno.net

What do you mean by, “You’re not routing your API key properly to your backend module”?

Again, everything is working except Outlook recipients.

Thanks!

So, I was correct on my approach. The CNAME records in Wix had to be modified. However, again, there was already a pre-existing entry s1._domainkey.somedomain.com and s2._domainkey.somedomain.com. Hopefully, this does not effect the baked-in email capabilities in Wix. Does anyone know?

I’m sure you have solved this by now, but I had the same issue today. The solution was to select the “Advanced” settings during the Sendgrid domain authentication process. There you will find the option to choose a custom DKIM, thus allowing you to use an alternative to the s1._domainkey.somedomain.com.

Yes. Thanks. I did solve the problem.
