# Quickstart · PHP

Send transactional email through Envimaily's HTTP API (`https://api.envimaily.com`) with **PHP**.

## 1. Account & key

1. Sign up at [https://app.envimaily.com/dev/signup](https://app.envimaily.com/dev/signup)
2. Create an `em_` key under **API keys**
3. Copy the token once — it is not shown again

## 2. Example

```php
<?php
$payload = json_encode([
  'from' => 'onboarding@envimaily.com',
  'to' => ['you@example.com'],
  'subject' => 'Hello from PHP',
  'html' => '<p>It works.</p>',
]);

$ch = curl_init('https://api.envimaily.com/v1/emails');
curl_setopt_array($ch, [
  CURLOPT_POST => true,
  CURLOPT_HTTPHEADER => [
    'Authorization: Bearer em_YOUR_KEY',
    'Content-Type: application/json',
  ],
  CURLOPT_POSTFIELDS => $payload,
  CURLOPT_RETURNTRANSFER => true,
]);
echo curl_exec($ch);
```

## 3. Without a verified domain

Use the shared test sender `onboarding@envimaily.com` and send only to the account owner email. After SPF/DKIM verification, send from your domain.

## 4. Limits
