How to Set Up Your SPF Record

Sender Policy Framework, or SPF, is an email validation system designed to detect email spoofing. 

Many large mail servers use SPF records to determine the legitimacy of an email address. To ensure that your emails maintain optimal deliverability, we recommend authenticating your domain with an SPF record.

Adding an SPF record is a form of email authentication, not a solution to fix poor delivery. This validation can help establish your sender reputation if you're just starting out, or protect performance that's already strong. If your sender reputation is poor, SPF authentication is unlikely to improve your reputation or boost your delivery.

Setting up Your SPF Record

Since each domain provider has a different platform layout, we have general instructions on how to complete this process:

  1. Navigate to your Domain Provider
  2. Locate the DNS editor/zone
  3. Add a record containing the following: v=spf1 mx ~all
  4. If prompted use the ‘@’ symbol for the host field
  5. Make sure to save your changes

For more detailed instructions, please refer to the documentation published by your domain provider.


SPF/DNS record issues are exclusive to your domain provider; we're only able to provide  very  limited troubleshooting support. So, if you do need help, your domain provider is the best point of contact. 
I use Cloudflare for hosting and can't add SPF records!

Use Cloudflare's guidance for adding TXT records. For more information, see Cloudflare's documentation.
