We're using the "Send to Kindle" email functionality for an application we have developed. We have noticed that if we send a document to a device email address, and the user of that device has not added our email address to the permitted sender's list, the user then receives a "Personal document received from unapproved sender" email from Amazon to let them know - which is great.
We were wondering if there was any way this notification to the user could be extended to include a link which, when clicked, would authorise the email address and send through the previously blocked document to the device, without the user having to ask us to resend it again?
Appreciate this would mean Amazon would need to store all unauthorised documents for a number of days, but it could potentially make life much easier for end users when they encounter this problem.
Thanks in advance for the consideration.
