Proactive Alert Monitoring: Daily Single Email Limits

Using the API or Apex, you can send single emails to a maximum of 5,000 external email addresses per day based on Greenwich Mean Time (GMT). Once the limit has been reached, all subsequent emails will fail to send. The emails that failed whilst the limit was hit must be re-sent after the limit is refreshed at midnight GMT the following day.

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. In addition, on the Salesforce Help site Designated contacts and above can see your realtime metrics, alerts & more.

If you receive the following error message(s), your organization may experience performance issues and possible service disruptions.

Full error message text:

• Apex/API Log Entry - SINGLE_EMAIL_LIMIT_EXCEEDED

Below are some possible scenarios that may result in this limit being hit:

• Poorly coded Apex batch submissions
