Privacy

Consent, tracking, data minimisation, and respectful measurement.

Tracking pixels and remote images

Treat open tracking as unreliable personal data collection, disclose it, minimise retention, and never make essential behavior depend on it.

Put only necessary personal data in message bodies, headers, links, logs, and provider metadata, with explicit retention for each copy.

Keep verifiable evidence of how and when each recipient subscribed, what they expected, and which message purposes that choice covered.
