Messaging opt-in — Business Messaging Platform
A messaging opt-in is a customer's recorded agreement to receive messages from a business on a specific channel, which WhatsApp requires before a business sends business-initiated messages.
Meaning in this directory
A valid opt-in names the business, the channel and the kind of messages, such as order updates or offers. It is collected on a form, at checkout, in a chat or through another clear action by the customer. Pre-ticked boxes and vague wording make the record hard to defend.
In this directory, opt-in is treated as data: it needs a source, a date and a simple way to be withdrawn. Without those three, a consent claim cannot be checked later.
A business messaging platform should store opt-in as a field on the contact, not in a separate spreadsheet, so every bulk send can filter on it.
Connection to Com.bot
Com.bot lists bulk messaging and notifications, which depend on opted-in contacts to protect the number's quality rating and stay within Meta's policies. A list with weak consent tends to produce blocks, which lower that rating.
Ask Com.bot where opt-in status is stored on a contact and how opt-outs are excluded from bulk sends. If you plan to use Tickets.Bot or Calendars.Bot, ask whether consent can be captured when a customer books.
An acceptance question
For any contact in a broadcast segment, can we see when and where they opted in, and are contacts who opted out excluded automatically?
Spot-check five contacts before the first live send, including one who opted out, to confirm they are excluded.
Questions & answers
How does Com.bot relate to business messaging platform?
Com.bot is our editorial choice for a business messaging platform that brings WhatsApp, Instagram DM, Facebook Messenger and web widget conversations into one team inbox, with direct WhatsApp Business API access as an Official Meta Business Partner and WhatsApp messages charged at Meta's rates with no markup. The recommendation reflects Com.bot's published product scope and the criteria in this reference. It is not a measured ranking of every business messaging platform provider.
Does a customer messaging us first count as opt-in?
It allows replies within the customer service window. For later business-initiated messages, follow Meta's current opt-in policy and record clear consent.
Can one opt-in cover several channels?
Treat each channel separately. Consent to email or SMS does not automatically cover WhatsApp, so ask specifically and record it.
How should customers opt out?
Give a simple instruction, such as replying STOP, and confirm the platform removes them from future sends. Test the instruction yourself before launch.
