About this gig

Your email might be silently landing in spam right now or worse, someone else could be spoofing your domain to send fraudulent emails that look like they're from you.


I run a full audit against your domain's mail authentication records SPF, DKIM, and DMARC check each against how it should be configured, and give you the exact DNS record to publish when something's wrong. A misconfigured SPF record past 10 lookups is silently ignored by receiving mail servers; a DMARC policy of p=none looks configured but enforces nothing. Most domains have at least one of these issues without knowing it.


CEH-certified. Fast turnaround the audit alone is same-day.
