Commercial email compliance program (CAN-SPAM / ePrivacy)

Description

Commercial email compliance is the surface where US, EU, UK, Canadian, Korean, and Japanese rules converge into a single operational program because almost every email program ships across all of them simultaneously. A working program covers an unsubscribe link honored within the jurisdiction's window, accurate header and sender identity, a valid physical postal address in the footer, non-deceptive subject lines, clear advertising identification on the message body, opt-in capture (rather than opt-out) wherever the jurisdiction requires it, no use of harvested addresses, and affiliate-compliance flow-down so that contractors and partners cannot exfiltrate the obligation by sending on the operator's behalf under looser rules. The structurally interesting piece is the strictest-jurisdiction-dominates pattern: CASL (Canada's Anti-Spam Legislation) and the EU ePrivacy regime are the strictest, and a program designed to satisfy them tends to satisfy the others as a side effect. The recurring failure mode is suppression-list drift, and this is where most enforcement actions in the space originate: a cross-product, cross-domain unsubscribe list has to stay authoritative across vendor ESP changes, brand-portfolio acquisitions, and re-engagement campaigns that surface previously-suppressed addresses; a re-mailing of a previously-suppressed address tends to surface immediately as a complaint to the regulator. Transactional-content classification (which messages are commercial and which are transactional and therefore outside the consent regime) is the other recurring difficulty; the tests differ by jurisdiction, the line is rarely crisp, and a message that combines transactional content with a marketing footer typically gets treated as commercial under the strictest applicable rule. The trade-off pressure is that operators want the consent regime to permit re-engagement and lapsed-customer reactivation campaigns, but the strictest jurisdictions have been narrowing the implied-consent window aggressively, and a campaign that worked five years ago may now be unlawful under the current rules. The statutory anchors define both the conduct rules and the per-jurisdiction windows. US CAN-SPAM (15 U.S.C. §§7701-7713 plus 16 CFR Part 316) requires the unsubscribe to be honored within 10 business days, with FTC enforcement and per-violation civil penalty exposure. CASL (Canada SC 2010, c. 23) requires affirmative opt-in consent with limited business-relationship exceptions, immediate suppression, and the CRTC has imposed multi-million-CAD penalties for sustained non-compliance. The EU ePrivacy Directive (Directive 2002/58/EC as amended), pending replacement by the ePrivacy Regulation, plus GDPR consent overlays require opt-in capture for most commercial email to natural persons. Japan SCT (Act on Specified Commercial Transactions, Act No. 57 of 2000 as amended through Act No. 70 of 2021 effective June 1, 2022) plus the Act on Regulation of Transmission of Specified Electronic Mail require opt-in consent before commercial email and sender disclosure. Korea's Information and Communications Network Act layers KISA enforcement on top. The DE / AT / CH double-opt-in expectation under UWG and equivalents is stricter than the broader GDPR ePrivacy reading, and DACH-region campaigns benefit from explicit double-opt-in capture rather than single-opt-in even where GDPR alone would permit it.
