DKIM signs every message so receivers can check it came from you unchanged. Your email provider generates the key; you publish it in DNS.

Why it matters. DKIM signs every message so receivers can check it really came from you and was not changed. DKIM also keeps forwarded mail passing DMARC, which SPF alone cannot.
How to fix it.
- Turn on DKIM signing in your email provider (Google Workspace, Microsoft 365, your newsletter tool) and publish the key record it gives you.
- DKIM keys live under a selector only your provider knows; if yours is set up, this check may simply not guess its name.
