DMARC, SPF and DKIM checker
DMARC, SPF and DKIM checker for your domain
A broken SPF include or a DKIM key rotated by your email provider sends your invoices and password resets to spam, and nothing tells you. Full Stack Audit checks your domain's email authentication records on a schedule and emails you when one breaks.
