WhatsApp Automation

Do I need customer opt-in to send WhatsApp messages?

Direct answer

Yes. Meta's policy requires customers to have agreed to be contacted on WhatsApp. For stores, the clean way is a checkout notice saying order updates arrive via WhatsApp. Transactional messages about an order the customer just placed are well within what customers expect; cold marketing to purchased lists is what gets numbers banned.

What counts as valid opt-in

  • A notice at checkout: "We will send your order confirmation and delivery updates on WhatsApp." Placing the order with that notice visible is the industry-standard opt-in for transactional messages.
  • A checkbox for marketing messages, kept separate. Order updates and promotional blasts are different consents.
  • The customer messaging you first, which is the strongest opt-in there is.

Why this protects you, not just customers

Meta enforces quality through block and report rates. A number that messages people who did not expect it accumulates reports and gets rate-limited or banned, taking your whole channel down. Order-related messages to people who just bought from you have near-zero report rates; purchased lists and cold blasts are how stores lose their number.

Practical rules

  1. Add the WhatsApp notice to your checkout page and post-purchase email.
  2. Send transactional content (confirmation, tracking, delivery day) freely to customers who ordered.
  3. Ask separately before marketing. An easy moment: after a successful delivery, "want us to message you about offers?"
  4. Honor "stop" instantly and automatically.

ReplAi keeps transactional and marketing consents separate and handles opt-out automatically, which keeps your number's quality rating healthy.
