How to use this tool

How to Guarantee Your Emails Reach the Inbox

Use our free Email Deliverability Toolkit to generate and validate your DNS records. Simply enter your domain name and your current (or desired) SPF, DKIM, and DMARC values. Our toolkit will instantly analyze your setup and provide a Deliverability Score out of 5, helping you avoid the spam folder.

What are SPF, DKIM, and DMARC?

SPF (Sender Policy Framework): Specifies which IP addresses and domains are authorized to send emails on behalf of your domain.
DKIM (DomainKeys Identified Mail): Adds a cryptographic signature to your emails, verifying that they haven't been tampered with in transit.
DMARC (Domain-based Message Authentication): Ties SPF and DKIM together, telling email providers (like Gmail and Outlook) what to do if an email fails authentication (e.g., quarantine or reject it).

100% Free & Private — No Limits

Testing your email setup shouldn't cost money. This tool is completely free of cost. There are no daily limits, no annoying paywalls, and no watermarks on any generated reports. Even better, it runs entirely on the client-side inside your browser—meaning we never track your domain names, API keys, or DNS configurations. Your privacy is totally secure.
