What is an SPF record checker?
Sendmarc’s SPF record checker is an online tool that fetches, analyzes, and validates the record for any domain. An SPF record checker allows users to:
- Test SPF to ensure the record exists and is correctly published in the domain’s DNS
- Validate the syntax and structure of the record to ensure compliance with standards
- Identify authorized IP addresses and third-party services permitted to send email on behalf of the domain
- Detect misconfigurations or excessive DNS lookups that can cause email delivery failures
Additionally, please check your company’s domain score to manage its domain to the highest DMARC levels.
Why does this matter?
SPF is an email authentication protocol that specifies which email servers are authorized to send messages on behalf of a domain. Without a valid record, a domain becomes vulnerable to email spoofing and phishing attacks. Misconfigured SPF records can also lead to legitimate emails being marked as Spam or Junk, reducing deliverability and damaging brand reputation.
Why your company should use an SPF record checker
Using a record checker is essential for organizations that want to maintain email security and deliverability. It ensures that domains are correctly configured to prevent abuse, protect reputation, and maintain compliance.
Key benefits
Prevent email spoofing
A record checker helps ensure that only authorized email servers can send messages on behalf of your organization’s domain.
Improve deliverability
Major email providers, including Gmail and Outlook, check SPF records to assess whether incoming messages are legitimate. A valid record increases the likelihood that emails are delivered to inboxes instead of being marked as Spam or Junk.
Detect and fix errors
The tool does an SPF syntax check to identify errors and excessive DNS lookups. These issues can result in emails being rejected by receiving email servers.
Ensure compliance
Email authentication standards and security requirements continue to evolve. Regular SPF checks help ensure that your business’s domain remains compliant with current best practices and technical standards.
Simplify management
Quickly review all authorized IP addresses, include mechanisms, and configuration details in your company’s record. This simplifies managing complex email environments.
