SPF
What is SPF?
Sender Policy Framework (SPF) lists the servers that are allowed to send email for your domain. Receiving servers check it to spot forged emails. Without it, your emails are likely to be marked as spam or rejected.
Add an SPF record
Do this for each cold email domain. In Cloudflare, select the domain and go to DNS > Records and add a TXT record.
- Google Workspace
- Zoho Mail
| Type | Name | Content |
|---|---|---|
| TXT | @ | v=spf1 include:_spf.google.com ~all |
See Google's SPF guide for more detail.
In the Zoho Mail Admin Console, go to Domains, select the domain, then Email configuration > SPF. Add the record shown, for example:
| Type | Name | Content |
|---|---|---|
| TXT | @ | v=spf1 include:zohomail.com ~all |
Copy the exact value Zoho shows. It depends on your region (for example include:zohomail.eu in Europe).
A domain must have only one SPF record. If one already exists, edit it instead of adding a second one. If you use another service that sends email from the same domain, add its include: to the same record.
You can check your SPF record with the MXToolbox SPF checker.
