How to Authenticate Your Domain
(SPF, DKIM & DMARC)
Step 1
Locate Your DNS Settings
You’ll find these in your domain provider’s control panel (e.g., GoDaddy, Cloudflare, IONOS, Namecheap).
Look for a section called DNS, DNS Zone, or DNS Records.
Step 3
Add the DKIM Record
Add the DKIM key we provide:
-
Type: TXT
-
Name/Host: (DKIM selector provided by Oyster)
-
Value: (DKIM public key provided by Oyster)
This digitally signs your emails so recipients know they’re genuine.
Step 5
Confirm with Oyster
Once the records are added:
-
Send us a screenshot, or
-
Tell us to verify the DNS automatically
We’ll activate email‑sending once everything is validated.
Step 2
Add the SPF Record
Add a TXT record:
-
Type: TXT
-
Name/Host: @
-
Value: (Oyster will provide your exact SPF value)
This tells mail servers that Oyster is authorised to send emails for your domain.
Step 4
Add the DMARC Record
Add a TXT record:
-
Type: TXT
-
Name/Host: _dmarc
-
Value:
v=DMARC1; p=quarantine; rua=mailto:you@yourdomain.com;
This protects your domain from spoofing and helps meet EU security standards
