Who is sending on behalf of your domain?

Between marketing automation platforms, CRMs, support tools and transactional email services, it's easy to lose track of all the systems that send email as you.

DMARCsimple ingests DMARC aggregate reports from major mailbox providers, groups them by sending source and shows you what's aligned—and what's not.

  • Identify third-party platforms sending as your domain
  • Spot misconfigured DNS records before deliverability drops
  • Detect spoofing and phishing attempts abusing your brand

From monitoring to enforcement—without breaking email.

Moving to a strict DMARC policy is powerful, but done too quickly it can cause real mail to be rejected. DMARCsimple helps you adopt a phased, data-informed approach.

  1. 1. Start in monitoring mode

    Publish a DMARC policy in monitor-only mode (p=none) and let DMARCsimple begin collecting reports.

  2. 2. Fix misconfigurations

    Use our suggestions and DNS check tools to correct SPF, DKIM and alignment issues for legitimate senders.

  3. 3. Gradually increase enforcement

    As more traffic passes authentication, safely move to quarantine (p=quarantine) and then full enforcement (p=reject).

Get started in a single afternoon

Most organizations can publish an initial DMARC record and begin monitoring their domains in just a few hours, especially when we collaborate with your internal IT or MSP.
