"user@example.com",
"Welcome!",
"Thank you for signing up!"
).await?;
```
**Use contact form component:**
```jsx
<ContactForm
title="Get in Touch"
recipient="contact@yourapp.com"
showSuccess={true}
/>
```
**Configure SMTP provider:**
```toml
[email]
provider = "smtp"
smtp_host = "smtp.gmail.com"
smtp_port = 587
smtp_username = "your-email@gmail.com"
smtp_password = "your-app-password"
smtp_use_starttls = true
```
The email system is now fully integrated into the Rustelo framework and ready for production use! It provides everything needed for form submissions, user communications, notifications, and more. The modular design allows developers to easily extend it with additional providers or customize the templates and forms for their specific needs.
