The Email-to-Case feature in Salesforce limits the number of Cases that can be created within an organization per day using the standard Email-to-Case method. The default daily limit for standard Email-to-Case is 2,500 Cases. This limit cannot be increased for standard Email-to-Case.
The daily limit resets at midnight GMT.
If the daily limit is regularly being reached, the On-Demand Email-to-Case feature should be used instead. On-Demand Email-to-Case provides a significantly higher daily limit based on the number of Salesforce licenses in the organization. Unlike standard Email-to-Case, the On-Demand Email-to-Case limit cannot be increased manually either, but the formula-based limit is generally much higher than the default 2,500.
The standard Email-to-Case daily limit of 2,500 Cases cannot be increased manually. If this limit is regularly reached, it is recommended to switch to On-Demand Email-to-Case, which provides a higher daily limit suited for high-volume environments.
The On-Demand Email-to-Case daily limit is calculated using the following formula:
1,000 multiplied by the total number of Salesforce licenses in the organization, up to a maximum of 1,000,000 Cases per day.
For example: An organization with 500 Salesforce licenses would have an On-Demand Email-to-Case daily limit of 500,000 Cases per day (500 × 1,000). An organization with 1,500 Salesforce licenses would be capped at the maximum limit of 1,000,000 Cases per day.
Note: The On-Demand Email-to-Case limit also cannot be increased manually beyond the formula-based calculation.
To enable On-Demand Email-to-Case for your organization, refer to the Set Up On-Demand Email-to-Case documentation in the Additional Resources section below.
