About DMARC Generator
DMARC Generator is a set of free tools for publishing and checking DMARC, SPF and DKIM records, for anyone who looks after a domain's email.
Why We Built This
DMARC is the standard way to stop other people sending mail as your domain, yet plenty of domains still don't have a working record. The syntax is easy to get wrong, the details are spread across several RFCs, and many of the tools that help want you to sign up first.
So every tool here is free and works without an account. You can check an existing record, create a new one, check up to 50 domains at once or read your DMARC reports, and each result says what to change and why.
Who Built This
DMARC Generator was built by Stephen Williams, a software engineer, who also maintains it. Questions, bug reports and suggestions are welcome through the contact page.
