# Send to E-Reader

1. **Configure SMTP once (admin)**

   Settings → E-Reader Email — host, port, encryption, credentials, and
   a from address.
2. **Set your e-reader's address (each profile)**

   Settings → Profile — the email address your e-reader accepts books
   at (a Kindle's `@kindle.com` address, for example).
3. **Send a book**

   From any book's menu, choose **Send to e-reader** — it's emailed as
   an `.epub` attachment.

## How it works

- Sending goes through [Nodemailer](https://nodemailer.com/) over the
  SMTP server configured in Settings → E-Reader Email — an admin-only
  section, since it's shared by the whole install
- Encryption is one of none, STARTTLS (typically port 587), or implicit
  TLS/SSL (typically port 465)
- Each profile has its own destination address, set on its own Profile
  settings page — the same SMTP server can deliver to every reader's own
  device
- The email is sent with the book's title as the subject and the
  original `.epub` as the only attachment

> **Allowlist the sender**
>
> Most e-readers only accept mail from approved senders — add the SMTP
> from address to your device's allowlist (Kindle calls this "Approved
> Personal Document E-mail List") or the email will be silently dropped.

> **Nothing sends without both pieces**
>
> If SMTP isn't configured, or the profile has no e-reader email set,
> "Send to e-reader" fails with a message pointing at whichever one is
> missing.
