What is the webinar about?

Third-party platforms and ESPs are deeply integrated into today’s email infrastructure. Multiple vendors often send on behalf of a single domain, each with its own authentication setup, configuration requirements, and infrastructure dependencies. Without a structured approach, inconsistencies can quietly introduce complexity, often making successful DMARC implementation and enforcement much harder to achieve.


This webinar focuses on the right strategies for securely working with third-party senders. We’ll discuss what needs to be configured properly from day one, what processes should be in place during onboarding and off-boarding, and how to maintain strong authentication and infrastructure hygiene without disrupting operations.

If your organization relies on multiple vendors to send email, this session will help you approach them strategically to ensure proper source configuration, alignment, and long-term DMARC maintenance across your email ecosystem.

What We’ll Cover

  • Third-party platforms and ESPs as part of your email infrastructure
  • The hidden risks behind these platforms
  • Initial email authentication & DMARC configuration challenges
  • Infrastructure challenges and vulnerabilities with ESPs.
  • ESP rotations: Onboarding/off-boarding sending sources
  • ESP infrastructure & customization impact on deliverability
