Returns export statistics for a given trackId. The trackId is from the Export People with Email endpoint. Use this endpoint to poll progress (e.g. statistics.total, statistics.found) and state until the job completes.

✅ Email Verification: All emails (SMTP & CATCH_ALL) returned by the API are verified in real time by BounceBan.

Fully-refunded submissions: if the submission was auto-refunded for non-delivery (STUCK_HARD_REFUND / STUCK_SOFT_REFUND), this endpoint returns 403 Forbidden with an actionable message — the results are not retrievable, so submit the request again. If it was refunded because there was no deliverable result (SEARCH_NO_RESULTS / NO_EMAILS_FOUND), it returns 200 with zeroed statistics.

The header Content-Type: application/json must be included in the request.
