Send email and newsletters to your Kindle

Why forwarding to @kindle.com does not work for newsletters

Every Kindle has a Send to Kindle email address ending in @kindle.com. Amazon converts documents attached to emails sent there and delivers them to your device. Two details make it awkward for anything but attachments:

• Only attachments are delivered. A newsletter, a Substack post or a long update from a colleague is the body of the email. Forward it to your Kindle address and there is nothing to convert.
• Only approved senders are accepted. Amazon ignores mail from any address that is not on your approved list, so a newsletter cannot be sent there by the publisher.

MXcatch handles both. You get an address on your own domain, kindle@your-domain.com. Whatever arrives there is sent on to your Kindle from a single MXcatch sender address you approve once — and when there is nothing attached, the email itself is converted to a PDF first.

What gets sent to the Kindle

• Supported attachments — PDF, EPUB, DOCX, DOC, RTF, TXT, HTML, JPG, PNG, GIF and BMP files are passed on to your Kindle address. Other attachments are left out.
• The email as a PDF — when an email has no supported attachment, which is the case for almost every newsletter, MXcatch renders the email to a PDF and sends that. The PDF has a short header with From, To, Date and Subject, then the body as it looks in the inbox, with images included.
• Both, if you prefer — turn on the option to always include the email as a PDF and you get the message text alongside any attachments, which is handy when someone writes context in the email and attaches the report.

The PDF uses the same rendering as email to PDF.

Setting it up

1. Find your Send to Kindle address. In Amazon's Manage Your Content and Devices, open Preferences → Personal Document Settings. Each device is listed with its …@kindle.com address.
2. Add your domain to MXcatch and point its MX records at us — per-provider instructions.
3. Create an alias, for example kindle.
4. Add a Send to Kindle action. Go to Domains → your domain → the alias → + Add action, choose Send to Kindle, and enter your @kindle.com address.
5. Approve MXcatch's sender address. The action dialog shows the address MXcatch sends from (kindle@ on MXcatch's sending domain). Add it under Approved Personal Document E-mail List in the same Personal Document Settings page. This is a one-time step.

Forward any email to kindle@your-domain.com and it appears in your Kindle library shortly after.

What people send to their Kindle

Newsletters and Substack posts

Subscribe using kindle@your-domain.com instead of your personal address. New issues skip your inbox and are waiting on the Kindle when you sit down to read.

Long emails you mean to read later

That essay a friend sent, a long project update, an article someone pasted into an email. Forward it and read it on a screen that does not buzz.

Reports and documents

Monthly reports, papers and manuals that arrive as PDF, EPUB or Word attachments are passed straight through to the device.

One Kindle per person

Each alias has its own actions, so anna-kindle@ and tom-kindle@ can deliver to different devices on the same domain.

Keep a copy too

Actions run independently. Add a Save to Dropbox or Google Drive action next to the Kindle one and every issue is also kept as a file, or use routing rules to send only certain senders to the Kindle.
