## Prerequisites

Before you start, you'll need:

* A Resend [API key](/docs/create-an-api-key)
* A [verified domain](/docs/add-a-domain)

## Guide

**1. Install**

Install by adding `resend` to your list of dependencies in `mix.exs`:

```elixir mix.exs theme={"theme":{"light":"github-light","dark":"vesper"}}
def deps do
  [
    {:resend, "~> 0.4.0"}
  ]
end
```

**2. Send email using HTML**

The easiest way to send an email is by using the `html` parameter.

```elixir send.exs theme={"theme":{"light":"github-light","dark":"vesper"}}
client = Resend.client(api_key: System.get_env("RESEND_API_KEY"))

Resend.Emails.send(client, %{
  from: "Acme <onboarding@resend.dev>",
  to: ["delivered@resend.dev"],
  subject: "hello world",
  html: "<strong>it works!</strong>"
})
```
