Error 'Probably Limit Exceeded or 0 recipients' in a Flow with a 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 go directly to the Selected Recipients List. Check which email field is defined as a recipient. Then, on the record that triggered the Flow, check if that email field has a value.

If the Flow has a Send Email action, open the Action element and review the values entered in the Recipient ID, Recipient Address Collection, Recipient Address List, CC Recipient Address List, and BCC Recipient Address List fields. If the action has a Recipient ID value, check if the Email field on the record that triggered the Flow has a value. If the Flow has values in the Recipient Address Collection, Recipient Address List, CC Recipient Address List, or BCC Recipient Address List fields, make sure that the variables in those fields contain an email value.

This error message results from having an email field that doesn’t contain an email address specified as a recipient. Also, if the recipient is an inactive user, you may get this error.

To resolve this error, you can do 3 things:

• Create a validation rule to require that the email field has value.
• Make the email field required on the field's detail page or in applicable page layouts
• Update your Flow so that the Send Email or Email Alert action should only fire when the email variable, or the triggering record’s Email field, has a value.
