What a Client Opt-in Letter Is and when it's used

A Client Opt-in Letter is a written notice used to obtain a client's affirmative consent to receive communications, participate in a program, or authorize a specific service. It documents the scope of consent (channels, purpose, duration), the effective date, and any opt-out method. In many business contexts the opt-in letter becomes a record of client permission that supports compliance with consumer protection, privacy, or industry-specific rules. The letter can be executed on paper or electronically, provided electronic execution meets legal requirements under ESIGN and applicable state law.

Why a clear opt-in letter matters for compliance and recordkeeping

A well-drafted Client Opt-in Letter clarifies what the client agreed to, reduces disputes about consent, and creates an auditable record to meet legal and regulatory requirements such as ESIGN (15 U.S.C. §7001) and state privacy laws.

Why a clear opt-in letter matters for compliance and recordkeeping

  • Marketing and Communications teams setting email/SMS consent preferences.
