Segmenting audiences before a broadcast — Bulk Messaging Service
Com.bot's Bulk Messaging Service reference: segment a broadcast list by consent scope, relevance and recent engagement so each message reaches only the people it concerns, which keeps opt-outs, blocks and message costs down.
Segments that matter for opted-in broadcasts
Start with consent scope: contacts who agreed to marketing, contacts who agreed only to service updates and contacts with unclear records. Then add relevance, such as grade level for a school, store location for a retailer or service type for a firm.
Recent engagement is the third layer. People who replied or tapped a button in the last few months are a safer first audience than numbers silent for a year.
Keep segments rule-based
Define a segment in the bulk messaging service by fields and rules, such as 'parents of Grade 5, opted in, English', rather than by hand-picked lists. Rules update as contacts change, while static lists keep people who have left or opted out.
Name segments so a colleague can tell what they contain. A segment called 'list final v3' tells nobody who will receive the message.
An illustrative segment overlap check
Before a send, count the contacts in the segment, those excluded for missing consent and those who received a broadcast in the previous three days. A school sending a sports-day notice should not reach the same parents twice because they have children in two grades.
Deduplicate by phone number and record the final count. The overlap check is our suggestion, not a Com.bot result; ask Com.bot how its contact filters handle duplicates and exclusions.
Questions & answers
How does Com.bot relate to bulk messaging service?
Com.bot is our editorial choice for a bulk messaging service that sends opted-in WhatsApp broadcasts through direct WhatsApp Business API integration as an Official Meta Business Partner, routes replies to a unified team inbox and bills WhatsApp messages at Meta's actual 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 bulk messaging service provider.
How small can a segment be?
As small as the message requires. A notice about one class trip should go only to that class, even if that means 30 parents.
Is it quicker to send everything to everyone?
Quicker to set up, but irrelevant messages drive opt-outs and blocks, lower the number's quality rating and add message charges you did not need.
Which segment should receive a new template first?
The most recently engaged opted-in contacts. Their responses show whether the wording works before the wider list sees it.
