Zammer

Consent Required

• Merchants may send messages only to recipients who have explicitly opted in.
• Opt-in must be collected through clear disclosure at checkout or via another verifiable method.

Opt-In Types and Rules

Zammer supports three distinct messaging use cases, each with its own opt-in requirements:

• Transactional (Checkout): The consumer provides their phone number at checkout. Messages are limited to order confirmations, shipping updates, and purchase-related notifications. No promotional content may be included.
• Marketing (Checkout opt-in): The consumer explicitly opts in to receive marketing messages via a checkbox at checkout. A CTIA-compliant confirmation message must be delivered before any marketing content is sent. Merchants may then send promotional offers and campaigns.
• Conversational (Website Widget): The consumer submits their phone number via a chat widget on the merchant's storefront. Zammer sends a double opt-in confirmation with Yes/No buttons. The thread is only created upon explicit confirmation. Merchant responses must be relevant to the consumer's inquiry. Marketing content may not be sent into this thread unless the consumer holds a separate marketing opt-in.

Transparency and Identification

• All messages must clearly identify the sending merchant or brand.
• Recipients must always know who is contacting them.

Opt-Out and Support

• Every message must include simple opt-out instructions.
• Recipients can reply STOP to unsubscribe or HELP for assistance.
• Opt-out requests must be honored immediately.

Cross-Thread Suppression

A consumer who replies STOP in any thread is suppressed across all active conversation threads with that merchant, regardless of which opt-in path was used. Suppression is applied immediately and is keyed on merchant + phone number. Merchants may not attempt to re-engage a suppressed number through an alternate thread.
