Email Authentication & DMARC with Sendmarc
Invoice fraud, CEO impersonation and phishing of your customers all start with someone sending email that looks like it came from your domain. DMARC is the control that stops it, but getting to enforcement without breaking your own mail takes visibility and care. Sendmarc gives us both; we do the work.
What you get
- Every service sending as your domain identified, including the ones nobody remembered
- SPF, DKIM and DMARC configured correctly for Microsoft 365, your PBX, CRM, billing and marketing platforms
- A managed path to DMARC p=reject, usually in weeks, without legitimate mail being rejected
- Attempted spoofing of your domain reported to you, with where it came from
- BIMI readiness so your logo shows in customers' inboxes once you're enforcing
- A report your cyber-insurer, auditor and customers' security questionnaires recognise
Who it's for
Any business that invoices by email, any domain holder (every one of them), and any company whose customers or insurer ask whether DMARC is enforced.
What's included
Discovery
Sendmarc's reporting shows every source sending as you, legitimate or not, before anything is changed.
Configuration
SPF flattening where records are too long, DKIM for each sending service, and a DMARC policy that moves from monitor to quarantine to reject on evidence.
Ongoing management
New senders onboarded, record changes handled, and policy kept at enforcement as your systems change. Included in managed security, or standalone.
Subdomains and parked domains
The domains you don't send from are locked down too, since attackers prefer them.
