1 The maximum size of email messages for email services varies depending on character set and transfer encoding of the body parts. The size of an email message includes the email headers, body, attachments, and encoding. Therefore, an email with a 35-MB attachment probably exceeds the 25-MB limit for an email message after accounting for the headers, body, and encoding. When sending an email from a record, attachments exceeding the size limit are sent as an .html link.
Single Email Limits
Each licensed org can send single emails to a maximum of 5,000 external email addresses, or recipients, per day. A day is based on Greenwich Mean Time (GMT).
Sending emails to internal email recipients doesn't count toward the org daily limit.
- For orgs created before Spring ’19, the org daily limit is enforced only for emails sent via Apex and Salesforce APIs, except for REST API.
- For orgs created in Spring ’19 and later, the org daily limit is also enforced for email alerts, simple email actions, Send Email actions in flows, and REST API.
- Each user can send emails from the email composer to a maximum of 250 external email recipients per hour.
In Developer Edition orgs and orgs evaluating Salesforce during a trial period, each user can send emails to a maximum of 50 recipients per day, and each single email can have up to 15 recipients.
