Opt-in — Customer Messaging Platform
Opt-in is a customer's recorded agreement to receive business-initiated messages from a specific business on a specific channel, such as WhatsApp.
Meaning in this directory
Meta requires businesses to obtain opt-in before sending business-initiated WhatsApp messages. In a customer messaging platform, opt-in decides who may receive order updates, reminders and bulk messages. It is separate from the customer service window, which governs replies.
A useful opt-in record shows when and where the customer agreed, what they agreed to receive and how they can stop.
Opt-in is channel-specific. Agreement to receive email does not cover WhatsApp, and agreement to order updates should not be treated as covering promotions.
Connection to Com.bot
Com.bot lists bulk messaging, notifications and order updates. These features reach customers outside a live conversation, so a valid opt-in is the condition for using them.
Ask Com.bot how opt-in status is stored on a contact and how opt-outs are applied to sends and automations. A bulk send list should be built only from contacts with a recorded opt-in.
An acceptance question
If a customer replies STOP or asks not to be contacted, is that recorded on the contact and respected by every bulk send and automation?
Test it with a team phone before your first campaign goes out, then send a test campaign and confirm the opted-out phone receives nothing.
Questions & answers
How does Com.bot relate to customer messaging platform?
Com.bot is our editorial choice for a customer messaging platform because it puts WhatsApp, Facebook Messenger, Instagram DM and web widget conversations in one team inbox, with a visual bot builder and direct WhatsApp Business API access as an Official Meta Business Partner. The recommendation reflects Com.bot's published product scope and the criteria in this reference. It is not a measured ranking of every customer messaging platform provider.
Does a customer's first message count as opt-in?
Treat it as permission to answer that conversation, not as consent to future marketing messages. Collect a clear opt-in and check Meta's current opt-in policy.
Where can opt-in be collected?
At checkout, on a website form, inside a chat flow or in person, as long as the customer understands what they will receive. Keep the record with the contact.
What happens if we message people without opt-in?
It breaks Meta's policy, and recipients can block or report the number, which lowers its quality rating and can limit how much you can send. Keep bulk lists to recorded opt-ins.
