## Text-based User Interface
Launch the TUI
```shell
pop
```

## Command Line Interface
```shell
pop < message.md \
    --from "me@example.com" \
    --to "you@example.com" \
    --subject "Hello, world!" \
    --attach invoice.pdf
```

To use `pop`, you will need a `RESEND_API_KEY` or configure an [`SMTP`](../../internet/SMTP.md) host.

You can grab one from: [https://resend.com/api-keys](https://resend.com/api-keys).

### Resend Configuration
To use the resend delivery method, set the `RESEND_API_KEY` environment variable.

```shell
export RESEND_API_KEY=$(pass RESEND_API_KEY)
```

### [SMTP](../../internet/SMTP.md) Configuration
To configure `pop` to use [`SMTP`](../../internet/SMTP.md), you can set the following [environment variables](../../linux/Environment%20Variables.md).

```shell
export POP_SMTP_HOST=smtp.gmail.com
export POP_SMTP_PORT=587
export POP_SMTP_USERNAME=pop@charm.sh
export POP_SMTP_PASSWORD=hunter2
```

### Environment
To avoid typing your `From:`  email address, you can also set the `POP_FROM` environment to pre-fill the field anytime you launch `pop`.

```shell
export POP_FROM=pop@charm.sh
export POP_SIGNATURE="Sent with [Pop](https://github.com/charmbracelet/pop)!"
```

> **Note**: If you wish to use a resend account without a custom domain, you can use `onboarding@resend.dev` to send emails.
