Service limits and fair use policy

Dynamics 365 Marketing relies on shared cloud resources for data and processing. This policy defines the limits for resource usage per org. These limits ensure that other tenants' performance is not affected and resources are evenly distributed.

The following tables show the current usage limits for Marketing features.

Outbound marketing

Feature	Attribute	Maximum
Segmentation	Number of live dynamic segments per org.	1,000 (both user defined and system created*)
Segmentation	Total number of segments.	10,000
Email sending	Interactions sent (email).	10,000,000 per month (1,000,000 daily max)
Email personalization	Number of dynamic attributes.	1,000
Email personalization	Number of entity relationships connected in personalization.	1 entity relationship (for example, contact.account, contact.events)
Data sync	Number of rows in a single synchronized table (for example, number of Marketing contacts).	30,000,000 rows
Data sync	Total rows across all synchronized tables.	100,000,000 rows

Note

System segments are created in three ways:

1. Whenever a unified segment is created (a behavior block plus a profile).
2. Whenever a journey uses multiple segments that will create a union of segments. For example, you can choose the source type and add multiple segments.
3. Whenever a behavior segment is used in journeys.
