Salesforce Proactive Alert Monitoring: Daily Workflow Email Limit

Salesforce applies limits to the total number of emails sent from workflows every 24 hours. The limit is 1,000 workflow emails per standard Salesforce license per organization. The overall organization workflow limit is 2,000,000. This applies to emails sent through email alerts in workflow rules, approval processes, flows, processes or the REST API. 

After your org has reached its daily workflow email allocation:

1. Any emails in the workflow queue not sent that day are discarded. Salesforce doesn't try to resend them later.
2. If a workflow rule with an action and an email alert is triggered, only the email action is blocked.
3. Final approval, final rejection, approval, rejection, and recall email actions are blocked.
4. An error message is added to the debug log.

The following items don't count against the workflow email allocation:

1. Approval notification emails
2. Task assignment notifications
3. Lead assignment rules notifications
4. Case assignment rules notifications
5. Case escalation rules notifications
6. Salesforce Sites usage alerts

The Signature Success plan’s Proactive Monitoring product will monitor for, and alert you to high consumption against this limit. This article outlines some scenarios to help you investigate should you receive an alert.  

The limit restriction is based on activity in the 24-hour period starting and ending at midnight GMT. Adding or removing a user license immediately adjusts the limit's total. If you send an email alert to a group, every recipient in that group counts against your daily workflow email limit.


Causes

A system limit exception will be raised when the Daily Workflow Email Limit is exceeded.

Possible high-limit consumption scenarios:

• Poorly configured workflow rules
• Poor API call setup and execution
• Activated triggers causing send failures
