Start with the hypothesis
The postmortem should begin with the intended test, not the dashboard. Which audience, pain, trigger, offer, and proof point was the campaign designed to evaluate?
Without that framing, the team can describe what happened but not what it means.
02 / 04
Review inputs before outcomes
Before interpreting replies, check whether the campaign ran as designed. If the list quality, deliverability, suppression, or handoff was broken, the outcome may not be a valid read on the market.
- 01 Audience and exclusion accuracy
- 02 Data completeness and verification
- 03 Sender health and delivery signals
- 04 Message variants and offer clarity
- 05 Reply handling and CRM handoff

Then classify the signal
Classify what the market said. Did a persona respond? Did an objection repeat? Did a segment fall flat? Did the buyer care but reject the ask?
McKinsey's B2B Pulse work is a reminder that buyers operate across many channels and interactions. A postmortem should interpret outbound as one signal in a broader buying process, not as a disconnected blast.
04 / 04
End with a decision
A good postmortem ends with one of four decisions: scale, iterate, isolate a variable, or stop. Anything vaguer usually means the campaign did not produce a usable read.
EO uses postmortems to make the next test more precise, not to create a prettier report.

Frequently asked questions
When should we run the postmortem?
Run it after enough sends and reply time to see a pattern, but before the team forgets the hypothesis and operating context.
Who should join the postmortem?
Include the person who owns GTM strategy, the operator who ran the campaign, and whoever handles replies or sales follow-up.
What if the result is inconclusive?
Name what is inconclusive and design the next test to isolate that variable instead of repeating the same campaign.
