Email deliverability

Understand what is getting in the way of delivery.

Caboodle investigates sending configuration, authentication, list practices, and available delivery signals. We turn the findings into a prioritized remediation plan and a monitoring process so changes can be evaluated over time.

What's included

Follow the evidence behind the delivery problem.

The final scope names the deliverables, dependencies, and review points before work begins. The work below provides the starting point for that discussion.
  • Sending inventory. List the systems, domains, addresses, and message types used to send business email.
  • Authentication review. Inspect available SPF, DKIM, and DMARC configuration and message-header evidence.
  • Delivery-data review. Examine available bounces, complaints, blocks, deferrals, and provider reporting.
  • List-practice assessment. Review subscription sources, suppression handling, engagement practices, and send frequency.
  • Message inspection. Check representative messages, links, sender identity, and the consistency of the sending setup.
  • Remediation priorities. Rank the configuration and operational changes by evidence, risk, and implementation effort.
  • Change coordination. Apply the agreed fixes with the relevant administrators and sending-platform owners.
  • Monitoring plan. Track available signals after changes and document unresolved issues and next actions.
How this works

Four steps from the first review to handoff.

Phase 1

Gather delivery evidence

Collect examples, headers, sending-system access, and available reports for the affected messages.
Phase 2

Diagnose the likely causes

Compare the evidence across authentication, sending behavior, audience practices, and provider responses.
Phase 3

Apply the agreed fixes

Make scoped configuration and operational changes with a documented reason for each.
Phase 4

Monitor the response

Review subsequent delivery signals and refine the plan as new evidence becomes available.
