Expanded Enforcement of Daily External Email Limit for New Orgs

Each org can send 5,000 single emails per day to external email addresses. For orgs created in Spring ’19 and later, this daily limit is also enforced for email alerts, simple email actions, Send Email actions, and REST API. If one of the newly counted emails can’t be sent because your org has reached the limit, we notify you by email and add an entry to the debug logs. For orgs created before Spring ’19, the daily limit is enforced only for emails sent via Apex and Salesforce APIs except the REST API.

Where: This change applies to Lightning Experience and Salesforce Classic in Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions.

Who: This change applies only to orgs that are created in Spring ’19 and later.
