SPF Lookup Tool

Check SPF records and review which senders are authorized to send email for a domain.

Secure lookup over HTTPS and live network resolution

Understanding Your SPF Lookup Results

SPF results show which mail servers are allowed to send email for a domain. This helps protect deliverability and reduce spoofing risk.
FOUND

SPF Record Found

A visible SPF record means the domain has published sender authorization rules in DNS.
REVIEW

Includes and Lookup Count

Too many includes or DNS lookups can cause SPF failures, especially when multiple email tools are connected.
DELIVERABILITY RISK

Invalid or Too Permissive SPF

Broken syntax or overly broad rules can hurt authentication, spoofing protection, and inbox placement.

About This Tool

What Is an SPF Lookup?

An SPF Lookup is a tool that retrieves the Sender Policy Framework (SPF) record published in a domain's DNS. An SPF record lists the mail servers and IP addresses that are authorized to send emails on behalf of a domain. Checking the SPF record helps verify that your email authentication is configured correctly and supports reliable email delivery.

Why Check an SPF Record?

Checking your SPF record helps confirm that only authorized mail servers can send emails using your domain. A properly configured SPF record reduces the risk of email spoofing, improves email deliverability, and helps receiving mail servers verify legitimate messages. Regular SPF checks also make it easier to identify configuration issues before they affect email communication.

What Information Does This Tool Show?

Our SPF Lookup Tool retrieves the published SPF record and displays important information, including:SPF record valueAuthorized IP addressesIncluded mail servicesRecord syntaxLookup mechanismsSPF policy (-all, ~all, or ?all)DNS lookup statusThis information helps you review your SPF configuration and identify potential issues.

Who Can Use an SPF Lookup Tool?

This tool is useful for website owners, email administrators, developers, IT professionals, and businesses that send emails using a custom domain. Whether you're setting up business email, troubleshooting delivery issues, or reviewing your DNS configuration, an SPF lookup provides a quick way to verify your domain's SPF record.

Best Practices for SPF Records

Keep only one SPF record for your domain and review it whenever you add or change an email service provider. Remove outdated entries that are no longer needed and monitor your configuration regularly to maintain reliable email authentication. Combining SPF with DKIM and DMARC provides stronger protection against email spoofing.

Why It Matters

1

Improve email authentication

Confirm that your legitimate sending services are included in the SPF policy.

2

Reduce spoofing risk

A clear SPF record helps receiving servers evaluate whether mail is authorized.

3

Catch syntax problems

Spot missing records, duplicate SPF entries, or unsafe mechanisms.

4

Support deliverability audits

Use SPF checks alongside DKIM and DMARC when reviewing domain email health.

How To Improve

1

Check the current SPF record

Enter the domain and review the TXT value beginning with v=spf1.
2

Include only approved senders

Add services that send mail for your domain and remove old platforms.
3

Avoid multiple SPF records

Use one combined SPF record instead of publishing several separate SPF TXT records.
4

Choose a safe all mechanism

Use provider guidance before setting -all, ~all, or other enforcement behavior.

Frequently Asked Questions

An SPF (Sender Policy Framework) record is a DNS TXT record that specifies which mail servers are authorized to send emails on behalf of your domain.
Common reasons include syntax errors, multiple SPF records, incorrect IP addresses, or too many DNS lookups. Reviewing the record can help identify these issues.
No. A domain should publish only one SPF record. Having multiple SPF records can cause email authentication to fail.
After updating your DNS settings, SPF changes may take anywhere from a few minutes to 48 hours, depending on your DNS provider and propagation time.
SPF verifies authorized sending servers, DKIM uses a digital signature to verify message integrity, and DMARC defines how email receivers should handle messages that fail authentication. Together, they improve email security.
A valid SPF record supports email authentication and helps receiving mail servers identify legitimate messages, which can contribute to better email deliverability.
Yes. After DNS propagation is complete, you can use the SPF Lookup Tool to confirm that your SPF record has been published correctly.
Yes. You can check the SPF record for any public domain online without creating an account.
