I would also greatly appreciate a per-recipient tracking report that we can use as documentation in legal proceedings. Concretely, something we can filter by recipient and export including, per message: Recipient, subject, and Message-ID Sent/scheduled timestamps and timezone Server acceptance / delivery status (and any bounce details) Opens and link clicks with timestamps (and, where available, IP / user agent) A tamper-evident signature or hash for evidentiary purposes For privacy and confidentiality reasons, I won’t be able to share entire messages, but I can provide partial headers or anonymized Message-IDs if needed for debugging.
