WhatsApp outreach

Use WhatsApp only after the person has given the business a mobile phone number and agreed to receive later messages or calls.¹ High message volume is rarely the cause of a blocked number or poor quality rating.² Sending to people without clean, provable consent can lead to blocks and reports that cause Meta's systems to throttle the sender.³

Complete the permission record before you plan the message. Move to the next stage only when the current one has a clear answer.

Stage	What you are trying to learn	Example question
Permission	whether the person chose to hear from the business	Did you actively choose to receive messages from this business?
Scope	what the person expects to receive	What did the permission say you would receive?
Proof	whether you can show how permission was given	Where is the record of the action?
Message	whether the next message helps the person move forward	What answer or resource would help now?
Exit	whether future contact remains welcome	How can this person stop future messages?

Build permission you can prove

Treat a phone number as contact detail until the permission record is complete. A clean record shows the person's active action, the business name, and a clear statement that the person will receive messages from that business.⁴

Collect permission where the person can make the choice directly. You can use a website, app, checkout page, SMS reply, or QR code.⁵ Choose the collection method as long as the permission meets the required conditions.

Keep the record attached to the person and the wording they saw. Meta's rules put the burden of proof on the sender.⁶ If a complaint arrives, you need to show that the person actively agreed.⁷ Review data protection law before relying on a permission flow because the platform rule does not replace those obligations.⁸

Double opt-in adds a confirmation step, and only confirmed contacts are added after that step.^{9, 10} Use it when the extra confirmation suits the motion. It is recommended as a best practice, while the policy does not require the second confirmation.¹¹

Set expectations at capture

The permission wording sets the boundary for later messages. Write it so the person knows who will contact them and what kind of contact follows.

A current policy update says the permission no longer has to state that delivery will happen specifically through WhatsApp.¹² A general opt-in for marketing or service messages, collected on any channel, can satisfy the platform requirement when it meets the stated conditions and local law.¹³ Keep the wording specific enough for a future reviewer to understand what the person agreed to receive.

Give people a clear way to leave. Users must always be able to opt out or unsubscribe from a business's messages.¹⁴ Check current WhatsApp Business documentation before launch because its policies and guidelines can evolve.¹⁵

Send something worth answering

Once permission is in place, use the conversation to help the buyer take the next step. The message should earn its place by answering a question, pointing to a resource, or making self-service easier.

Customers want to self-serve, and salespeople should guide them to resources and answer their questions when they arise.¹⁶ WhatsApp can guide prospects quickly when it is positioned appropriately for the buyer.¹⁷ Keep the response close to the question in front of you, and avoid turning a permissioned thread into a sequence of unrelated pitches.

The conversation gives the recipient direct access to the person handling the exchange, so be ready to answer when the recipient replies. Read status can show whether messages have been opened and read.¹⁸ Use it as a visibility signal, then wait for an actual response before treating the conversation as active.

What not to do

The common mistakes are confusing possession of a number with permission and making the exit path hard to use.

• Do not treat a phone number collected from an order as WhatsApp consent.¹⁹
• Do not use a number that was scraped, purchased, or imported from another platform as proof of consent.²⁰
• Do not rely on a pre-checked checkbox that a person must undo to decline.²¹
• Do not bury consent in Terms of Service acceptance when the wording does not mention the messaging permission.²²
• Do not use generic language such as "subscribe for updates" without naming the business.²³
• Do not create a permission flow that gives people no way to opt out or unsubscribe.¹⁴

If the record cannot show the person's action and the business they agreed to hear from, repair the capture point before contacting anyone.
