Frequently Asked Questions
What are SPF, DKIM, and DMARC records?
These are DNS records that help verify email authenticity. SPF (Sender Policy Framework) specifies which servers can send email from your domain. DKIM (DomainKeys Identified Mail) adds a digital signature to emails. DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receiving servers what to do with emails that fail authentication.
Why are these email authentication records important?
Properly configured email authentication helps prevent email spoofing and phishing attacks, improves email deliverability, reduces the chance of your emails being marked as spam, and protects your domain's reputation. Many email providers now check for these records when deciding whether to deliver messages.
How do I fix issues with my email DNS records?
If this tool identifies problems with your SPF, DKIM, or DMARC records, you should work with your email service provider or DNS administrator to correct them. Each email service (like Google Workspace, Microsoft 365, or SendGrid) provides specific instructions for setting up the correct DNS records for their service.
