Fields

Field	Type	Required	Description
x-direct-marketing:jurisdiction_variant	enum	REQUIRED	The applicable direct marketing regime. Permitted values: gdpr, uk_pecr, us_can_spam, us_tcpa, canada_casl, australia_spam_act, other.
x-direct-marketing:legal_model	enum	OPTIONAL	The consent model under the applicable regime. Permitted values: opt_in, opt_out, objection_right, mixed_channel_specific. Note: GDPR Article 21(2) is an objection right; CAN-SPAM is primarily opt-out for commercial email; CASL is opt-in; TCPA requires prior express written consent for autodialled/prerecorded telemarketing calls.
x-direct-marketing:channel	array of enum	CONDITIONAL	Required where data is processed for direct marketing. Permitted values: email, sms, telephone_automated, telephone_live, post, push_notification, in_app, social_media.
x-direct-marketing:opt_out_flag	boolean	OPTIONAL	Set to true where the data subject has exercised their right to object to direct marketing under GDPR Article 21(2) or equivalent opt-out/unsubscribe rights. Processing for direct marketing must cease. Note: GDPR Article 21(2) is an absolute objection right; CAN-SPAM and similar regimes create unsubscribe obligations. These are legally distinct mechanisms.
x-direct-marketing:suppression_list_checked_flag	boolean	OPTIONAL	Set to true where applicable suppression lists or do-not-call registries have been checked. Note: CAN-SPAM does not operate through a national suppression registry; TCPA interacts with Do Not Call frameworks.
x-direct-marketing:sender_identification_flag	boolean	OPTIONAL	Set to true where sender identification duties under CAN-SPAM, CASL, and Australia Spam Act have been satisfied.
x-direct-marketing:casl_consent_type	enum	CONDITIONAL	Required when jurisdiction_variant is canada_casl. Permitted values: express, implied, none. Note: CASL recognises both express and implied consent in defined circumstances.
x-direct-marketing:us_telemarketing_consent_type	enum	CONDITIONAL	Required when jurisdiction_variant is us_tcpa and channel includes telephone. Permitted values: prior_express_consent, prior_express_written_consent, not_required_for_this_call_type, unknown. Note: prior express written consent requirement depends on call type, technology, and whether the communication is telemarketing.
x-direct-marketing:can_spam_compliant_flag	boolean	OPTIONAL	Set to true where commercial email to US recipients complies with CAN-SPAM requirements including accurate headers, valid physical address, and clear opt-out mechanism. Note: CAN-SPAM is primarily an opt-out compliance regime for commercial email, not an opt-in consent law.
x-direct-marketing:australia_spam_act_consent_flag	boolean	OPTIONAL	Set to true where consent has been obtained for commercial electronic messages to Australian recipients under the Spam Act 2003. Messages must also include sender identification and a functional unsubscribe facility.

Revision notes

• jurisdiction_variant added as REQUIRED field: GDPR objection right, CAN-SPAM opt-out, CASL opt-in, and TCPA written consent cannot be represented by a single shared enum.
• legal_model added to capture the fundamental differences between regimes.
• casl_consent_type enum added: CASL recognises implied consent in defined circumstances.
• us_telemarketing_consent_type enum added: TCPA requirements vary by call type.
• consent_basis (single cross-jurisdiction enum) removed: replaced by jurisdiction-specific fields.
• sender_identification_flag added covering CAN-SPAM, CASL, and Spam Act identification duties.
