+## Text message (SMS)
+_Supported on:_ :material-android: :material-apple: :material-firefox:
+
+You can forward messages as text message (SMS) by specifying a phone number a header. Similar to email notifications,
+this can be useful to blast-notify yourself on all possible channels, or to notify people that do not have the ntfy app
+installed on their phone.
+
+To forward a message as an SMS, pass a phone number in the `X-SMS` header (or its alias: `SMS`), prefixed with a plus sign
+and the country code, e.g. `+12223334444`.
+
+On ntfy.sh, this feature is only supported to [ntfy Pro](https://ntfy.sh/app) plans.

+## Phone calls

+
+You can forward messages to e-mail by specifying an address in the header. This can be useful for messages that 
+you'd like to persist longer, or to blast-notify yourself on all possible channels. 
+
+Usage is easy: Simply pass the `X-Email` header (or any of its aliases: `X-E-mail`, `Email`, `E-mail`, `Mail`, or `e`).
+Only one e-mail address is supported.
+
+Since ntfy does not provide auth (yet), the rate limiting is pretty strict (see [limitations](#limitations)). In the 
+default configuration, you get **16 e-mails per visitor** (IP address) and then after that one per hour. On top of 
+that, your IP address appears in the e-mail body. This is to prevent abuse.
