Frequently Asked Questions

Authentication (SPF, DKIM, DMARC, and BIMI where relevant), DNS configuration, sending domain and IP reputation, blacklist status, gateway placement across the major filters (Microsoft EOP, Proofpoint, Mimecast, Barracuda, Google), list hygiene, and the ESP or sequencer setup itself. For cold outbound programs it also covers domain and mailbox architecture and warming state. You get findings mapped to specific fixes, not a generic checklist.

The audit is a diagnostic. It ends with a written report, a prioritized remediation roadmap you can hand to any team to execute, and a review call. Remediation is not included in the audit price. After the audit, we recommend three months of monitoring and support, or remediation work can be scoped separately at a fixed price.

An audit takes 7 to 10 business days from when we receive access to your systems to the review call.

Read access to your DNS, your ESP or sequencer, and any inbox-placement or reputation tooling you already run. For gateway filtering issues we also ask for a few seed addresses on the receiving side so we can run placement tests against real environments.

No. We are ESP-agnostic and audit whatever you send on, whether that is Instantly, Apollo, Smartlead, Klaviyo, HubSpot, Mandrill, Resend, or a self-hosted setup. Cold outbound, marketing, and transactional each get evaluated as their own program with their own standards.
