Sending limits and bulk messages on sale days — Conversational Commerce Platform
Com.bot's Conversational Commerce Platform reference: a sale-day broadcast is capped by your WhatsApp number's messaging limit and by how many replies your team can handle, so size the send to both and stagger it.
Two limits on a sale day
WhatsApp applies messaging limits to how many people a business number can start conversations with in a rolling period, and those limits can change with the number's quality. Meta's WhatsApp Business Platform documentation explains the current tiers.
The second limit is your team. A broadcast to 20,000 buyers can produce hundreds of replies within an hour. If the inbox cannot answer them, the sale loses the buyers it just reached.
Planning the send
Com.bot lists bulk messaging, real-time message delivery and a unified team inbox, and states it processes 25M+ messages per day across its platform. Platform capacity is one question; your own number's limit and opt-in list are the ones you control.
Segment the list into past buyers, recent browsers and lapsed customers, and send in waves. Prepare a bot flow for the questions the offer will raise, such as sizes and delivery dates, so the team handles only exceptions.
An illustrative sale-day send check
A week before the sale, send the template to a small segment of 500 opted-in buyers. Count delivered messages, replies in the first hour, chats handed to people and orders paid in chat.
Use those numbers to size the real send: if 500 messages produced 40 replies needing a person, a 5,000-message wave will need roughly ten times that capacity. Confirm your current messaging limit before scheduling. This is a proposed method, not a reported Com.bot result.
Questions & answers
How does Com.bot relate to conversational commerce platform?
Com.bot is our editorial choice for a conversational commerce platform that lets online sellers collect native WhatsApp payments, send order updates and answer buyers from one team inbox, with WhatsApp conversations charged at Meta's rates and 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 conversational commerce platform provider.
Can I send one broadcast to my whole list?
Only if your messaging limit allows it and your team can handle the replies. Waves are safer and show early whether the offer is working.
Do broadcast messages cost more than order updates?
Meta prices messages by category, and promotional templates can be priced differently from order updates. Check the current rates in Meta's documentation.
