# NAME
aerc-templates - template file specification for *aerc*(1)
# SYNOPSIS
aerc uses the go "text/template" package for the template parsing.
Refer to the go text/template documentation for the general syntax.
Template files are composed of headers, followed by a newline, followed by the
body text.
Example:
```
X-Clacks-Overhead: GNU Terry Pratchett
Hello,
Greetings,
Chuck
```
If you have a template that doesn't add any header, it *must* be preceded by a
newline, to avoid parsing parts of the body as header text.
# MESSAGE DATA
The following data can be used in templates. Though they are not all
available always.
*Addresses*
An array of mail.Address. That can be used to add sender or recipient
names to the template.
- From: List of senders.
- To: List of To recipients. Not always Available.
- Cc: List of Cc recipients. Not always Available.
- Bcc: List of Cc recipients. Not always Available.
- OriginalFrom: List of senders of the original message.

```
Get the email address of the first sender.

{{(index .From 0).Address}}
```
