Check your emails with

We recently launched a service to check your emails against standards, guidelines, and best practices. This service is called EmailAudit and is available on It checks DNS, SPF, headers, DKIM, DMARC, and more. The results are not a simple pass or fail, but contain detailed information on compliance and suggestions for fixing.

EmailAudit was developed in-house and has had a long history of throw-away prototypes. After trying several languages and frameworks we settled with JRuby and Torquebox. By using the latest reference libraries for SPF, DKIM, and DMARC we make sure that the results are accurate and standards compliant. A few weeks ago we finally released it for public testing.

The service is offered for free to anyone. The number of tests you can request is limited to 3 per 24 hours to give all users a fair share. You just need to submit your email to receive a notification when the audit is ready. We won’t be nagging you and your data is kept private. We do recommend that you read our privacy policy before using the service.

Start checking your emails today and go to We welcome any feedback, such as suggestions for additional checks. Of course we can also help with making your emails compliant. Do not hesitate to contact us in case of questions.
