Frequently Asked Questions

Find answers to the most commonly asked questions below.

What is an SPF record?

An SPF (Sender Policy Framework) record is a DNS TXT record that specifies which mail servers are authorized to send emails on behalf of a domain, helping to prevent email spoofing and phishing attacks.

How does the SPF Checker work?

Our SPF Checker retrieves your domain’s SPF record, verifies its syntax, checks for errors, and ensures it follows best practices for email authentication.

Why is my SPF record important?

A properly configured SPF record helps improve email deliverability, prevents unauthorized email use, and reduces the chances of your emails being marked as spam.

What does -all, ~all, and +all mean in SPF records?

  • -all (Fail): Emails not from authorized servers are rejected.
  • ~all (SoftFail): Unauthorized emails are marked but still delivered.
  • +all (Allow All): Not recommended, as it allows any server to send emails for your domain.

What happens if my SPF record is incorrect?

An incorrect SPF record can cause email delivery issues, leading to emails being rejected, sent to spam, or failing authentication checks like SPF, DKIM, and DMARC.

How can I fix SPF record errors?

Our SPF Checker identifies common errors, such as multiple SPF records, syntax mistakes, or excessive DNS lookups. You can correct these by updating your domain’s DNS settings with the correct SPF configuration.

Can I have multiple SPF records for a domain?

No, a domain should have only one SPF record. If multiple SPF records exist, email authentication may fail, leading to delivery problems.

How can I check my domain’s SPF record?

Simply enter your domain name into our SPF Checker on DNSLoader, and the tool will analyze and display your SPF record along with any detected issues.
