Email blocked DMARC

550 5.7.26 This mail has been blocked because the sender is unauthenticated. Gmail requires all senders to authenticate with either SPF or DKIM. Authentication results: DKIM = did not pass SPF [musedigitalmedia.net] with ip: [209.85.220.41] = did not pass For instructions on setting up authentication, go to Email sender guidelines - Google Workspace Admin Help x195-20020a25e0cc000000b00dc6baa2262dsor2788600ybg.12 - gsmtp

It seems like you may previously have followed some bad advice, or otherwise incomplete instructions about setting up email authentication for your domain.

Are you still sending email out through SendGrid?

  1. YES?
    Change your SPF record to:
    v=spf1 include:_spf.google.com include:sendgrid.net -all

  2. NO?
    Change your SPF record to:
    v=spf1 include:_spf.google.com -all
