Hi Felix,
It is an annoying change at Amazon’s end. Especially as they don’t make clear exactly how they determine when verification is needed.
One Push to Kindle user wrote:
I changed my send-to-kindle address from
john.smith@kindle.comtojohn.smith_new@kindle.combut I still received the verification email. It wasn’t until I changed the email to something more significantly different likejsmith22@kindle.comthat the article was sent directly without verification.
In our own tests, this is still the case. In most cases adding kindle@fivefilters.org as an approved address in your Kindle account and telling Push to Kindle to use that is enough to avoid these verifications emails (assuming the first part of your Kindle address doesn’t contain ‘kindle’).
Can’t you provide a service for paying customers to receive the forwarded verification requests and somehow automatically verify them by calling the link.
As far as we’re aware, these verification emails go the main email address associated with the Amazon account, not to any address passed in via Push to Kindle. So any solution would also require the user to set up automatic forwarding of these verification emails to our own handler. It should be possible, but we’d want to be able to reproduce the problem ourselves first.
If there are other users reading this with this problem (where changing the email addresses so that the send to address and the send from address being significantly different still produces these verification emails), please let us know.
