Introduction
Limitations in Mapp Engage help ensure that individual contacts are not overwhelmed by too many messages within a short period. This is particularly useful when a contact belongs to several groups and might otherwise receive multiple messages in a day. Limitations apply to all messaging channels (email, SMS, and mobile push) but exclude system messages and single messages.
Common Use Cases
Message limitations are commonly used to:
Prevent over-communication and improve the user experience.
Maintain deliverability and reduce the risk of unsubscribes.
Apply consistent communication caps across multiple campaigns or groups.
Types of Message Limitation
Mapp Engage supports three types of message limitations. If more than one limitation is active, the most restrictive rule always takes precedence.
Default Limit
Every Mapp Engage system has a built-in default that restricts each contact to a maximum of 9 messages per day. This safeguard cannot be changed or overridden, even by custom configurations.
System-Wide Message Limitation
Administrators can define a stricter limit than the default across the entire system. This is helpful when multiple campaigns target a contact in a short span. Once the limit is reached, no further messages are sent until the time period resets. System-wide limits do not apply to system messages and single messages. Group managers and owners also continue to receive all messages for their groups. For more information, see Create System-Wide Message Limit.
Contact-Specific Message Limitation
Individual limits can be set per contact via XML import. These overrides are useful for honoring contact-level preferences or business-specific communication policies. For more information, see Define Contact Message Limitation.
Note:
Both system-wide and contact-specific limits are only active in groups where the message limitation feature is enabled. For more information, see Enable Message Limitation for Group.
Example
Two message limitations are defined:
A 6-day limit: maximum of 5 messages within any 6-day period.
A 1-day limit for Mapp Engage: maximum of 2 messages per day.
Message Delivery Outcome:
Day 1: The recipient receives 2 messages (daily limit reached).
Day 2: The recipient receives 2 more messages (daily limit reached again).
Day 3: Although the daily limit allows for two more messages, only one message is sent. This is because the 6-day total limit of 5 messages has already been reached.
