+// title Refunds
+
+You can request a refund for unused Certified Mail postage. Refunds are not available for normal First Class letter postage.
+
+To request a refund, [click here to contact us](https://postalportal.net/#contact). Include the tracking number on your unused envelope.
+
+If you don't have the tracking number, include the date and time of purchase, along with the last four digits of your credit card so we can look up your transaction.
+
+It may take up to 45 days to receive a refund, because USPS can take up to 30 days to process it on their end.
+
+Your refund will go back to your original payment method.
+
+Thank you for using Certified From Home!
