Ask for help: customers can message you from their order page

Customers can type a message on their order page and it is emailed straight to you, with their own address as the reply-to, so you can simply hit reply. The email includes their name, the order total, the items and a link to the order in your admin. You can send the customer a copy, add extra staff inboxes and set your own subject line. If the tool's own destination is not set, messages go to your Customer support email instead of failing, and repeated messages about the same order are limited to prevent abuse. The confirmation a customer sees only appears once the email has really been accepted for delivery, and the default reply speaks as your store.
