Modifiche per invio a Kindle

In 2025, you can still email documents to your Kindle using the "Send to Kindle" feature, but after April 1, 2025, Amazon is changing its rules for security reasons. You must now add full, specific email addresses (such as “[email protected]”) to your approved senders list—partial email addresses (like “@xyz.com”) will no longer work. If you attempt to send a document from an incomplete or unapproved email, delivery will fail and you’ll be notified by Amazon ^{[1] [2]}.

To send files to your Kindle:

• Find your device’s unique Kindle email address in your Amazon account settings.
• Make sure the sender email is in your approved personal document e-mail list (now only full email addresses are permitted).
• Attach your document (supported formats include EPUB, PDF, DOC, DOCX, TXT, RTF, HTM, HTML, PNG, GIF, JPG, JPEG, or BMP) ^{[3] [5]}.
• Leave the subject and body of the email blank; simply attach the file and send it ^[4].

Important details:

• You can send up to 25 files in a single email, with a total attachment limit of 50MB (but keep individual attachments below your email provider’s limit, usually 25MB) ^[5].
• If you encounter problems, check sender approval, email content, attachment size/type, and your device’s connection and software updates ^[5].

These changes will particularly affect institutions and companies that previously used domain-based whitelisting for bulk Kindle deliveries, but should have minimal impact on individual users who manage their approved emails carefully ^{[1] [2]}.
