Overview
This topic explains the difference between group and single messages in Mapp Engage. Understanding how each message type works helps ensure correct tracking, evaluation, and usage in your campaigns.
Message Types
Group Messages
Sent to some or all members of a group.
Created using the Message Creation wizard.
Considered group messages even if segments or A/B tests are applied.
Each sendout has a unique Message ID (MID) and its own statistics.
All sendouts appear individually in the Outbox.
Subject to message limitation settings.
Single Messages
Sent to one specific contact.
Used for personalized or system-triggered communications, such as:
Shipping details
Birthday greetings
Order confirmations
Automated responses to user activity
Includes system, transactional, and automated single messages.
All sendouts share a single MID and a combined statistics set.
Only one sendout is visible in the Outbox.
Not evaluated in message limitation.
