Reset Email Analytics Baselines After Click Tracking Changes

Reset the reporting baseline whenever click-recording coverage changes. Migma can show campaign and link-level results for messages it sends, but a lower recorded click rate after a privacy-control change may reflect fewer observable recipients—not weaker creative. Keep coverage, behavior, and attribution as separate series.

Klaviyo's September 8 click-tracking controls take effect prospectively and can remove click events from reporting, attribution, segments, and triggers. Previously recorded events remain. That creates a measurement boundary at the setting's effective time.

Keep a coverage ledger#

For each reporting interval, record:

Do not estimate unobserved clicks by multiplying the tracked group's rate across everyone unless a documented method justifies that inference.

Publish two rates, not one#

Use the ordinary delivered-denominator rate for continuity:

recorded click rate = recorded unique clickers / delivered recipients

Also report a coverage diagnostic:

tracking coverage = tracking-eligible recipients / delivered recipients

If your system can prove the tracked population and link eligibility, a third diagnostic may compare recorded clickers with tracking-eligible recipients. Label it clearly; it is not the same metric as the standard delivered-denominator click rate and may describe a systematically different population.

Mark the baseline break#

Create a timeline with four points:

1. last full interval under the old policy;
2. exact setting-change timestamp;
3. transitional interval containing both policies;
4. first full interval under the new policy.

Exclude the mixed interval from simple before/after charts or annotate it visibly. Segment historical dashboards by policy version rather than drawing one uninterrupted trend line.

Use Migma evidence without overclaiming#

Migma's campaign results document delivery, clicks, click maps, A/B results, and per-recipient logs. Its metric glossary distinguishes sent from delivered and notes that clicks are recorded link events. Preserve the exact campaign, artifact version, audience, send time, and metric definition with each export.

For creative review, use the click map to locate recorded action differences, then inspect the actual email. Do not treat an empty map region as proof that nobody used the link when tracking coverage is incomplete.

Rebuild comparisons around equivalent exposure#

Before comparing two campaigns, match or disclose:

• delivery denominator and exclusion rules;
• tracking coverage and link exceptions;
• audience definition and consent geography;
• offer, destination, and observation window;
• bot filtering and unique-versus-total logic;
• attribution model and conversion metric;
• creative and send-time changes.

A comparable campaign is not merely the previous row in a dashboard.

Separate decision paths#

Version the analyst handoff#

When creative is built or revised in Migma, attach the measurement contract to the reviewed artifact. Migma's export guidance requires final-platform checks because the destination can add wrappers and apply its own rules. Confirm which links are tracked in the stored template and received message, not only in the editable source.

The release record should name the policy owner, analyst, campaign owner, effective timestamp, query or dashboard, raw counts, coverage ratio, and known gaps.

Stop conditions#

Stop comparative reporting when tracking-eligible population is unknown, a mixed-policy interval is presented as homogeneous, link exceptions are unrecorded, standard and coverage-adjusted rates share one label, attribution settings changed without annotation, or a dashboard export cannot be tied to a policy version.

Evidence limits#

Klaviyo documents how its new controls affect recorded events and downstream products. Migma documents its own result surfaces and metric definitions. Marketing Wiki did not test event suppression, dashboard calculations, bot filtering, attribution, audience composition, or statistical comparability. The ledger exposes those unknowns; it does not recover unobserved behavior.
