Add your SPF record at your domain provider

Protect against phishing & prevent messages from being marked as spam

To turn on SPF for your domain, add a DNS TXT record at your domain provider.

Keep in mind: 

  • The field names in these steps might be different for your domain provider. DNS TXT record field names vary for domain providers.
  • After adding an SPF record, it can take up to 48 hours for SPF authentication to start working.

Add your SPF record

Sign in to the management console for your domain host and locate the page where you update DNS TXT records for your domain. For help on how to find this page, check the documentation for your domain provider.

Enter these values on the page or form for your domain provider’s TXT records:

Field name Value to enter
Type TXT
Host

@

Note: If you're adding a SPF record for a subdomain, enter the subdomain instead of @. Read Apply an SPF record to subdomain with the Host setting for more information.

Value

If you only send email from Google Workspace, enter this SPF record:

v=spf1 include:_spf.google.com ~all


If you use additional email senders, enter the SPF record you created in Basic setup or in Advanced setup.
TTL 1 hour or 3600 seconds

Subdomains

When you add your SPF record to your domain, the SPF record isn't automatically applied to subdomains. Check if your domain provider lets you add SPF records directly to subdomains. If you're not sure, check the documentation for your domain provider.

Add an SPF record directly to subdomain

If your domain provider lets you add SPF records directly to subdomains, locate the subdomain in your domain provider management console. Then, add an SPF record following the steps in Add your SPF record.

For example, if your domain is solarmora.com, you might want to add an SPF record for the subdomain mail.solarmora.com. Locate mail.solarmora.com in your domain provider console and add the SPF record.

Apply an SPF record to subdomain with the Host setting

If your domain provider doesn’t have a way to add an SPF record directly to a subdomain, add another SPF record to your primary domain. Change the Host value to apply the SPF record to the subdomain.

Follow the steps in Add your SPF record, but for the Host value, enter the subdomain instead of @.

For example, if your domain is solarmora.com, you might want to add an SPF record for the subdomain mail.solarmora.com. Enter mail in the Host field, instead of @.

Update your SPF record for added senders

Every time you start using a new mail server or third-party sender, you should:

  1. Update your SPF record, following the steps in Define your SPF record.
  2. Add the updated SPF record at your domain provider, following the steps in Add your SPF record.

If you don’t update your SPF record, messages sent by the new senders might be marked as spam.

Important: Your domain should have one SPF record only. The exception is when you Apply an SPF record to a subdomain with the Host setting. Your domain provider might let you add more than one SPF record to the same domain. However, SPF won’t authenticate messages correctly if there are multiple SPF records for the same domain.

Next steps

When you add the SPF record at your domain, you’re done setting up SPF for your domain. It can take up to 48 hours for SPF authentication to start working.

If you’re having issues verifying SPF is working, or if messages from your domain are still going to spam, follow the recommendations in Troubleshoot SPF issues.

We recommend you also set up DKIM and DMARC authentication for your organization.
