SPF Lookup Tool
Check your domain's SPF records to prevent email spoofing.
What is an SPF Lookup Tool?
An SPF (Sender Policy Framework) lookup tool checks the SPF record of a domain to verify which mail servers are authorized to send emails on behalf of that domain. SPF helps prevent spoofing and improves email deliverability by allowing recipient servers to confirm if the sending server is authorized.
How to Use the SPF Lookup Tool
- Enter the Domain: Input the domain name you want to check (e.g.,
example.com). - Click 'Check SPF Record': The tool will fetch the SPF record from the domain's DNS settings.
- Review the Result:
- v=spf1: SPF version.
- ip4 / ip6: Authorized IP addresses.
- include: Third-party services allowed to send emails.
- -all / ~all: Indicates strict or soft SPF policy.
Frequently Asked Questions
1. Why is SPF important for email deliverability?
SPF prevents unauthorized senders from using your domain, reducing the risk of spam and phishing. It also improves your domain's email reputation, boosting deliverability.
2. What does "SPF record not found" mean?
It means the domain does not have an SPF record configured, which can lead to authentication failures and poor email deliverability.
3. How do I create or update an SPF record?
Add or modify a TXT record in your domain's DNS settings with your SPF policy. Example: v=spf1 ip4:192.168.1.1 include:_spf.google.com -all
