If you are not receiving important emails from Parts Portal, such as account setup quotes, order confirmations, etc., your email provider may be filtering them into spam. To ensure delivery, you can whitelist our sending domain (@custompartsportal.com) by adding it to your Safe Senders List or Allowlist.

Follow the steps below for your email provider. Please note, your IT administrator may need to assist if your organization has strict email filtering policies.
