Limits and Guidelines
There are limits that apply to your usage of Marketing Cloud Engagement. Salesforce implements some of these limits, and some are due to external factors.
Overview
We group limits into two categories: usage limits and scale limits. When usage limits are exceeded, features can become unavailable, performance can be throttled, or billing charges can be applied. Usage limits are typically related to resource consumption. For example, the maximum size of a data extension or the maximum number of objects in an API request are both usage limits.
Scale limits are typically related to throughput rates that can’t be exceeded. Scale limits are often outside of the control of Salesforce. For example, mobile phone carriers in many countries impose limits on the volume of messages that can be sent from a single phone number in a given period. This external factor creates a limitation on the scale of a campaign that sends SMS messages.
- API Limits and Guidelines
Use the Marketing Cloud Engagement APIs to integrate your applications and other technology systems with Marketing Cloud Engagement. To protect our Service and ensure the availability of Marketing Cloud Engagement for all customers, Salesforce places limits on API usage. - Data Extension Limits and Guidelines
The size and structure of your data extension and contact attribute data can impact their performance. To optimize the performance of your data extensions and contact attributes, stay within recommended ranges. - Data Retention Limits and Guidelines
Marketing Cloud Engagement limits how long it stores some of the data related to your account. - Database Query Limits and Guidelines
Query limits protect the health and performance of the Marketing Cloud Engagement database. There are two types of limits: hard and soft. If you issue a query that exceeds a hard limit, the request is rejected. You can exceed a soft limit, but doing so can degrade performance. Salesforce reserves the right to limit the execution of queries that exceed soft limits if they cause system performance or security issues. - Email Limits and Guidelines
There are several ways to use Marketing Cloud Engagement to send email, including Email Studio, Journey Builder, SOAP API, and REST API. When you send email, there are limits that apply to throughput, file size, and data retention policies. - SMS Limits and Guidelines
