When a Salesforce Approval Process step includes a rejection action that sends an email to the previous approver, two emails are sent to that approver instead of one.
When an approver rejects a record, Salesforce performs the following:
The approver request email is automatically sent any time someone is assigned as an approver in a Salesforce Approval Process. This behavior is not directly configurable — however, the workaround below resolves the duplicate email issue.
This issue occurs because the Rejection Behavior is configured to notify the previous approver via a rejection action, while Salesforce simultaneously sends a standard approval assignment email. To prevent the duplicate, consolidate the messaging into a single approval request email that covers both scenarios.
This way, only one email is sent to the approver — the standard approval assignment email — which now contains all necessary context for both new assignments and rejection re-assignments.
