WHAT IT SOLVES
Protect your reputation before someone else uses it.
Email authentication reduces domain impersonation risk and helps receiving systems distinguish legitimate business email from fraudulent mail.
Legitimate mail reaches spam
Misaligned or incomplete authentication can damage delivery to customers and suppliers.
Unknown services send as you
CRMs, invoicing platforms, websites and marketing tools may all use your domain without central visibility.
DMARC reports are unreadable
Raw XML reports are difficult to interpret and easy to ignore until something breaks.
THE MANAGED SERVICE
From visibility to enforcement—without breaking genuine email.
Publishing a DMARC record is only the beginning. We identify legitimate senders, correct authentication, monitor reports and move the policy safely from observation toward quarantine or rejection.
01DiscoverMap Microsoft 365, websites, CRMs, payroll, invoicing, marketing and every other sender.
02AuthenticateCorrect SPF, enable DKIM and align authorised services with the visible From domain.
03MonitorAnalyse DMARC reports, spot unknown sources and verify legitimate mail continues to pass.
04EnforceProgress safely toward quarantine or reject policies once approved sources are ready.
05ManageReview new services, DNS changes, threats and delivery issues on an ongoing basis.
WHY NOW
Major mailbox providers expect authenticated email.
Google and Yahoo require stronger authentication for bulk senders and recommend it broadly. Poorly authenticated messages may be rejected, limited or treated as spam.
SPF or DKIM for all senders
Bulk senders must use SPF, DKIM and DMARC, with alignment requirements for direct email.
Google sender guidelines →Authentication for bulk senders
Yahoo requires SPF and DKIM plus a valid DMARC policy for bulk sending.
Yahoo best practices →One policy across every sender
KnowIT brings business email, marketing systems, websites and SaaS platforms into one controlled view.

COMMON QUESTIONS
DMARC without the jargon.
Will DMARC stop all phishing?
No. It helps prevent direct spoofing of your domain, but it cannot stop lookalike domains, compromised accounts or every phishing technique. It should form part of layered email security.
Can DMARC break legitimate email?
A rushed enforcement policy can affect unauthenticated senders. That is why we begin with discovery and monitoring, correct legitimate systems, and only enforce when the evidence supports it.
Do you need access to our DNS?
DNS changes are required. KnowIT can implement them with authorised access or provide exact records for your existing IT or hosting provider to publish.
Does this work with Microsoft 365 and Google Workspace?
Yes. We also account for websites, marketing platforms, ticketing, CRM, invoicing and other authorised services sending from your domain.
