Why your RoutineInk sending address is yours
How Amazon's approved-sender list works, why the complete address matters, and why every RoutineInk account has a permanent sender.
· RoutineInk
Amazon will not accept a document for your Kindle unless the address it came from is on a list only you can edit. This is the single step that decides whether any send-to-Kindle service works, and it is the step most of them explain badly. Here is what the list is, why the complete address matters, and how it shapes RoutineInk is built.
What the list is
Every Amazon account has an Approved Personal Document E-mail List: a set of sender addresses
allowed to mail documents to your @kindle.com address. Mail from anywhere else is refused. It
exists so that knowing someone's Kindle address does not let you put files on their device — a reasonable
rule that happens to be the main source of confusion in this category.

Amazon's approval list is designed for individual sender addresses. Add the complete address shown in
RoutineInk—not only @somekindleservice.com—so Amazon can match the document to the sender you
approved.
The address you approve has to be your address, character for character. Every RoutineInk account therefore gets its own permanent sending address, which stays the same for the life of the account.
Why yours and not ours
A per-account address keeps each approval specific to one RoutineInk account. It also makes the address
something to copy rather than something to know. Yours looks like this, but the
letters after the u are yours alone:
Seven characters after the u, from an alphabet with no i, l, o, 0 or 1 — because this gets read aloud and typed by hand.
Then we test it
RoutineInk sends a one-page test document to a new Kindle and watches for a refusal. If Amazon returns one, we match it to the test and show what to fix. If no refusal arrives after about 30 minutes, the Kindle is marked ready. Amazon does not provide a positive delivery receipt, so you can still check the document on the device if you want to confirm it visually.
If it still refuses
- Check the account. The approved list is per Amazon account. If you have a personal and a work account, the Kindle is registered to exactly one of them.
- Check for a stray space. Pasting from a chat app often brings a trailing space or a zero-width character with it. Use the copy button in the dashboard.
- Check the destination address too. A typo in the
@kindle.comaddress produces a different refusal — "no such address" rather than "not approved" — and RoutineInk tells the two apart for you. - Give it a minute. Amazon's approval list is not instant. If you approve and send in the same breath, one retry usually settles it.
