Overview
Sender Policy Framework (SPF) records authorize your emails with a mail server and confirm that you're the one sending e-mail from your domain. SPF records accomplish this by listing a range of IP addresses that are authorized to send on your behalf. Any receiving email domain that detects anything outside of the range registers the email as spoofed or spam.
Check out the following sections to configure your domain's SPF records.
Verify SPF Record
Your domain's SPF records are typically managed by your IT department or domain administrator, but you can also check SPF records with a tool like MX Toolbox. Just enter your domain and click SPF Record Lookup.
The lookup returns your current SPF record configuration.
Add SPF Record
If you followed the steps above and found an SPF record, there's no need to configure it any further.
If your domain doesn't have an SPF record, follow these steps to enable it:
- Google Workspace:
- Office 365:
Using a provider other than Google or Microsoft? SPF setup instructions depend on your domain or email provider. Reach out to your IT team or domain administrator if you need help.
If you're the IT or domain administrator for your organization, verify that you have the correct list of IP addresses. Email servers could mark your emails as spam if you misconfigure your SPF record.
Next Steps
SPF records are only one part of an email deliverability strategy. You should also set up DKIM and DMARC records to further validate your organization's domain.
