Salesforce Flow Error: Probably Limit Exceeded or 0 Recipients in Send Email or Email Alert Action

If the Flow has an Email Alert action, open the Email Alert under Setup > Process Automation > Workflow Actions > Email Alerts and review the Selected Recipients list. Check which email field is configured as a recipient and confirm that the field on the triggering record contains a valid email address.

If the Flow has a Send Email action, review the values configured in the following fields:

• Recipient ID
• Recipient Address Collection
• Recipient Address List
• CC Recipient Address List
• BCC Recipient Address List

If a Recipient ID is used, verify that the related Email field contains a value.

If Recipient Address Collection, Recipient Address List, CC Recipient Address List, or BCC Recipient Address List fields are used, ensure that the variables contain valid email addresses.

How to Identify the Email Alert in the Flow

1. Go to Setup.

• • In Lightning Experience, click the Gear icon in the upper-right corner and select Setup.
  • In Salesforce Classic, click Setup in the upper-right corner.

2. In the Quick Find box, search for "Flows."
3. Under Process Automation, select Flows.
4. Open the Flow that triggered the error.
5. Double-click the Email Alert element referenced in the error email.
6. Review the configuration panel. The Email Alert name appears:

• • In the panel title
  • In a text field in the middle of the panel

Resolution Options

To resolve this error, you can:

1. Create a validation rule to require that the email field contains a value.
2. Make the email field required on the field detail page or applicable page layouts.
3. Update the Flow so the Send Email or Email Alert action runs only when the email variable or the triggering record’s Email field contains a value.
4. For Derived Field Issue: Create an custom email field and update the custom email field with the related record email address using field update automation and then use the custom email field in the email alert.
