How to fix it

  1. DKIM — Turn on DKIM signing in your email provider and publish the TXT/CNAME it gives you
    (record value comes from your provider's admin panel)

DNS changes can take up to 24–48 hours. Re-run the check afterwards.

Want it fixed for you? I set up SPF, DKIM and DMARC without breaking your other senders, with a before/after report.
