Email Compliance Requirements
Map each core email‑compliance requirement (unsubscribe, address, subject line, header/body) to the regulations that enforce it.
The most common email regulations — CAN‑SPAM (US), CASL (Canada), and GDPR (EU/UK) — share four core technical requirements. Select a requirement below for detailed guidance and implementation steps.
Unsubscribe / Opt‑out Mechanism
Required — CAN‑SPAM, CASL, GDPREvery commercial email must include a clear, functional link allowing recipients to opt out of future emails. Simply Send provides a managed unsubscribe system by default, or you can connect your own via webhooks.
Physical Postal Address

Email Headers
