Require a Reproduction Brief With Every AI Email Report

Before an AI-generated report changes a Migma email, require enough evidence for another analyst to reconstruct the finding. Save the question, data scope, metric definition, extraction time, supporting rows, and calculation alongside the proposed creative change.

Migma is useful as the place to investigate the sent email and revise its creative after a finding survives scrutiny. Its metric definitions distinguish receiving-server acceptance from inbox placement; its campaign results guide describes live-updating statistics and recipient-level inspection. Those give a reviewer concrete evidence boundaries. They do not make every explanation of a rate change true.

The September reporting change#

Customer.io’s September 10, 2026 release note says its agent, CLI, and MCP tools can analyze messaging and behavioral data for custom reports. Its conversational analytics documentation describes that reporting surface. This expands the kinds of questions an operator can ask; it does not establish that a conversational answer is causal or reproducible.

For a team using Migma for creative and a separate system for analysis, keep the transfer explicit: pass the verified finding and supporting aggregate evidence into the creative brief. No new direct Migma–Customer.io integration is asserted here.

Ask for a report receipt, not a confident paragraph#

Use this original request with the analyst or reporting tool:

Question: Which onboarding message should we investigate first?
Scope: Named campaigns and versions only; exclude tests.
Period: Explicit start/end instants and reporting timezone.
Metric: Define numerator, denominator, uniqueness and exclusions.
Evidence: Return grouped counts and the calculation for each row.
Freshness: State extraction time and whether delivery is complete.
Uncertainty: Name missing data and alternative explanations.
Action: Recommend an investigation; do not change or send campaigns.

If the tool cannot expose source rows, ask for the smallest available aggregate that independently reproduces the answer. If even that is unavailable, retain the output as a hypothesis. A polished chart is not a substitute for the missing denominator.

The receipt should also preserve any follow-up prompts. “Exclude internal accounts” changes the report population. “Use the last completed week” changes the period. Saving only the first prompt makes the final answer difficult to reproduce even when its arithmetic is correct.

A small denominator mistake changes the story#

Here is a synthetic example, not Migma account data. One message has 1,000 send attempts, 800 accepted deliveries, and 40 unique clickers. The clicker share is 5% of deliveries and 4% of attempts. Both calculations are arithmetically valid; only one answers a question defined as clickers divided by delivered messages.

A report that labels both “click rate” can make an unchanged campaign appear to improve. Ask the analyst to reproduce 40 ÷ 800 and state whether the numerator is unique people, unique message recipients, or total events. Do not infer that every product uses the same event deduplication from a familiar metric label.

Next, check extraction time. If delivery was incomplete when one report ran, the later denominator may differ. Freeze the export used for the decision so a future reviewer can explain that difference without recreating old live state.

Translate one supported finding into one Migma revision#

Suppose the report identifies a low rate of recorded clicks on the setup CTA. Inspect the actual sent message before requesting a rewrite. Was the destination correct? Was the action relevant to that cohort? Did the report include recipients who had already completed setup?

Then brief a bounded change: “Make the setup action explicit in this email; preserve the approved offer and other links.” Re-review the resulting Migma draft. The report receipt remains attached to the decision; it does not become a permanent claim that this design is inferior.

This differs from flow triage: the immediate task is proving what the reporting conversation counted. It also differs from an experiment demonstrating incremental impact. We have not run Customer.io analytics, evaluated report accuracy, or measured any creative outcome. Start by reproducing one consequential row before acting on the full report.
