Salesforce enforces daily email sending limits to protect deliverability and prevent spam. These limits apply to single emails sent via Apex, Workflow, and Process Builder, as well as to list emails and mass emails sent from the platform.
Understanding which limit applies to your use case helps you plan email campaigns and automated messaging effectively.
The single email limit is the maximum number of individual emails Salesforce can send per day from a single org. This limit includes emails triggered by Apex code, workflow email alerts, and process automation.
The daily limit resets at midnight GMT.
Developer Edition and Trial orgs have lower email limits than production orgs. These limits exist to prevent abuse of free and sandbox environments.
For email limits specific to Trial and Free orgs, see the Additional Resources section below.
This article explains the email sending limits enforced by Salesforce across different org types and email sending methods.
To monitor your org's daily email usage, navigate to Setup > Email > Email Log Files and request a log covering the relevant time window. Email logs show all outbound emails sent from the org, including automated emails from Apex and workflow rules.
If your org requires a higher daily email limit, contact Salesforce Support with your org ID and business justification. Limit increases for single email APIs are evaluated on a case-by-case basis.
For mass email and list email limits, refer to the Salesforce Help documentation linked in the Additional Resources section.
