Messaging Opt-in Policy

How customers should obtain and manage user consent before sending SMS, WhatsApp, and other communications.

Last updated: 2026-07-01

Consent Requirements

Customers must obtain required user consent before sending marketing, notification, OTP, WhatsApp, or other business messages, according to applicable law, platform policies, and target-market requirements.

Opt-in wording should clearly identify the sender, message types, channels, possible frequency, cost notice, and opt-out method.

Consent Records

Customers should retain consent source, timestamp, page or form, opt-in wording version, phone number, channel, IP address, or other records that prove authorization.

Opt-out and Withdrawal

Each marketing or subscription message category should provide a clear and effective opt-out method. After a user opts out or withdraws consent, the customer should stop the relevant outreach promptly and update opt-out lists across its own systems and suppliers.

Prohibited Use

Do not send marketing messages to users without authorization, bypass opt-out requests, buy unknown-source numbers for bulk outreach, or impersonate brands, financial institutions, government bodies, or platforms.
