GoHighLevel Email Domain Authentication: SPF, DKIM and DMARC Explained
SPF, DKIM and DMARC are the three records that tell receiving mail servers your GoHighLevel emails are legitimate. They do not guarantee inbox placement, but without them your messages start with a strike against them. Understanding what each one does helps you set them up correctly and avoid the common mistakes.

What each record does
Each record answers a different question about your email. SPF lists which servers are allowed to send on behalf of your domain. DKIM adds a cryptographic signature so the receiver can verify the message was not altered in transit. DMARC ties them together with a policy that tells the receiver what to do if authentication fails. Together they prove your email is genuinely from you.
| Record | What it proves | Common mistake |
|---|---|---|
| SPF | Which servers may send for your domain | Forgetting to include the GoHighLevel sending server |
| DKIM | The message was not altered in transit | Using the wrong key or an outdated record |
| DMARC | What to do when authentication fails | Setting a policy too strict before records are verified |
What to check first
- Confirm your sending domain is verified in GoHighLevel.
- Check that an SPF record exists and includes the sending server.
- Check that a DKIM record is published and valid.
- Check whether a DMARC record exists and what policy it sets.
- Use a DNS lookup tool to confirm the records resolve correctly.
SPF in plain terms
SPF is a list published in your DNS that says which mail servers are allowed to send email for your domain. When a receiving server gets a message, it checks the SPF record to see if the sending server is on the list. If it is not, the message looks suspicious. The record must include the GoHighLevel sending server or your emails will fail this check.
DKIM in plain terms
DKIM adds a digital signature to the message that the receiver can verify against a public key in your DNS. If the signature matches, the message was not changed after it was sent. This protects against tampering and helps the receiver trust the message. The key in your DNS must match the one the sending system uses, or the verification fails.
DMARC in plain terms
DMARC is a policy that tells receivers what to do when SPF or DKIM fail. It can monitor, quarantine or reject failing messages. A common mistake is setting DMARC to reject before SPF and DKIM are fully verified, which can block legitimate email. Start with a monitoring policy, confirm your records work, then tighten the policy.
Use the records for your configuration
The exact DNS values depend on your specific setup and email provider. Do not copy generic values from a guide. Use the records GoHighLevel provides for your domain and the records your DNS host expects. A wrong value can break authentication or block email entirely, so confirm each record against your actual configuration before you publish it.
How to set up authentication
- 1.Verify your sending domain in GoHighLevel.
- 2.Publish the SPF record including the sending server.
- 3.Publish the DKIM record with the correct key.
- 4.Start DMARC with a monitoring policy.
- 5.Test with a lookup tool and a real send before tightening DMARC.
Frequently Asked Questions
What are SPF, DKIM and DMARC for GoHighLevel email?
SPF lists which servers may send for your domain, DKIM signs the message so the receiver can verify it was not altered and DMARC sets a policy for what to do when authentication fails. Together they prove your email is genuine, though they do not guarantee inbox placement.
Do I need all three records for GoHighLevel email authentication?
All three work together. SPF and DKIM do the verification and DMARC ties them together with a policy. Missing any one weakens the proof that your email is genuine. Start DMARC in monitoring mode, confirm SPF and DKIM are valid, then tighten the DMARC policy.
