How To Add DKIM Records
Learn how DKIM records work and how to add them to DNS so email providers can verify messages from your domain.
In short
Add DKIM records in DNS exactly as your email provider gives them. DKIM lets receiving servers verify that a message was authorized by your domain.
Key points
- DKIM records are usually TXT or CNAME records.
- Copy the host/name and value exactly.
- DKIM uses cryptographic signatures to verify email.
- ZidiMail shows the records needed for domain verification.
| DKIM field | What it means |
|---|---|
| Selector | A label that identifies the DKIM key |
| Host/name | The DNS location for the record |
| Value/target | The public key or CNAME target |
| Status | Whether the provider can verify it |
Where DKIM lives
DKIM is configured in your domain DNS. Your email provider gives you the host and value to add. Some providers use TXT records, while others use CNAME records.
Why exact copying matters
Small changes in the host, selector, or value can prevent verification. Copy the record exactly, including punctuation and provider-specific prefixes.
Why DKIM matters
DKIM helps prove the email was not forged or changed in transit. It is one of the most important signals for trusted domain sending.
