Enable measurement
Open Reports in Free for optional campaign/link click counts and retention settings. Basic tracking is off by default; review your notice and subscriber choices before enabling it. Pro adds order attribution, its matching window and journey breakdowns. No open pixels or tracking cookies are used.
Read the numbers carefully
A link request can come from a person or scanner. Orders match only when a logged-in WordPress customer follows a measured link and that same customer makes a paid order within the configured window. Guest and cross-device purchases may not match. Totals reflect recorded refunds and remain separated by currency; they do not demonstrate incremental sales.
Respect individual preferences
Edit a subscriber to exclude them from measurement. Retention cleanup and WordPress privacy export and erasure handle related records. Existing links still open after removing Pro while Free and the original signing salts remain; changing WordPress auth salts invalidates signatures.
