Send-to-Kindle Won’t Work on Unsupported Kindles; Amazon Phasing Out Older Formats

April 13, 2026 by Nathan Groezinger 3 Comments

Kindle Paperwhite 1

Ever since Amazon started sending out emails last week about dropping support for older Kindles, I’ve been seeing some people say you’ll still be able to use Send-to-Kindle or email to send documents and non-Amazon ebooks to those Kindle devices, but unfortunately that is not the case.

Moving forward, all Kindles released before 2013 will only support transferring documents via USB. If your Kindle is jailbroken you’ll have other options, but the stock software will no longer support wireless delivery of any kind.

Amazon confirms this on the unsupported Kindles help page on their website. They should’ve made it one of the main bullet points to make it clearer, but they put it toward the bottom behind parenthesis:

You can transfer personal documents to impacted E-Readers using a USB cable (Send to Kindle option won’t be available).

They probably want to phase out support for older Kindle formats entirely at this point. It started when they discountinued the download and transfer option for ebooks last year. That’s most likely the real reason why they are doing this now. Older Kindles don’t support the newer KFX format so it’s easier to just drop support for them.

They can give the convenient “security” excuse, but the fact is those older Kindles haven’t been updated in many years anyway. They aren’t any more of a security risk now than they were a year or two ago. The Kindle Paperwhite 1 is the latest model that Amazon is dropping support for, and the last time it was updated was in 2015.

On the plus side, if phasing out support for older formats is the goal, that means Amazon shouldn’t be dropping support for any other older Kindle models anytime soon. Some people are concerned about the Voyage and other older Kindles getting the boot next, but they might remain supported for a long time still, especially now that Amazon has come up with a way to deliver ebooks with hardened DRM to older Kindles without updating them.

I was wondering why the Paperwhite 1 was the cutoff, but it makes sense considering the Paperwhite 2 is the oldest Kindle model to support KFX format. Someone just posted a comment this morning saying their Paperwhite 2 is getting ebooks with the new hardened DRM now. The timing is a little too convenient for this to be a coincidence. This whole thing is about making DRM removal more difficult, and Amazon is willing to cutoff support for older devices to accomplish that.

    This isn’t uncommon all across electronic devices. Apple, Android, Microsoft. Samsung, all do this at some point. They do it to simplify support. But more importantly to increase sales.

    My question is whether the web browser will work and whether I can use send.djazz.se to send files in MOBI/AZW3 format.

      It should just be Amazon’s servers that won’t serve you books, so you’ll probably still be able to do that
