Customer consent (opt-in)

Before you message a customer on WhatsApp first, you need their consent. This is a Meta requirement: marketing templates may only be sent to people who have explicitly agreed to receive messages.

Consent is not “turned on” anywhere in the product — the platform does not store or verify it. Collecting it, keeping a record, and being able to prove it is the business’s responsibility.

Who is responsibleCopy Anchor Link

Responsibility for obtaining valid consent rests with the platform customer. This is stated in our terms: the user is responsible for complying with WhatsApp Business Terms, Meta policies, anti-spam laws, and marketing communication rules.

1MSG does not influence Meta’s decisions — not account approval, not sending limits, not quality rating, and not blocks.

What you must not doCopy Anchor Link

Using the service prohibits:

• sending unsolicited or unlawful messages;
• working with purchased or unauthorized contact lists;
• violating applicable anti-spam laws;
• circumventing opt-in requirements;
• engaging in misleading communications.

What happens without consentCopy Anchor Link

Messages to people who did not expect them lead to spam complaints. Consequences come from Meta’s side:

• the number’s quality rating drops;
• sending limits are reduced;
• the number may be restricted or blocked.

Explicit consent lowers the risk of complaints and helps avoid a number block.

How this relates to the 24-hour windowCopy Anchor Link

Until the customer messages you first, the window is closed — the first message is sent as a template. When the customer replies, the window opens, and you can continue with free-form text.
