There is a limit in sending emails using Resend for Free Tier with a limit of 100 emails per day and 3,000 email per month
Once you have added the API key in .env file go to your route.ts file and add the following snippet.
```javascript
import { render } from "@react-email/render";
import WelcomeEmail from "../../../emails";
import { Resend } from "resend";
const resend = new Resend(process.env.RESEND_API);
export async function POST(request: Request, res: Response) {
const { email } = await request.json();
const { data, error } = await resend.emails.send({
from: "onboarding@resend.dev",
to: email,
subject: "This is a test email",
html: render(WelcomeEmail()),
});
if (error) {
return Response.json(error);
}
return Response.json({ message: "Email sent successfully" });
}
```
In the above code we are importing the template which we have created earlier. and then we are setting up the from and to email address. For the trial purpose we will use "onboarding@resend.dev" and if you have custom domain to send email we will see how to do that in few mins.
Now run the next application using the following command.
```bash
npm run dev
```
Now we will send the email open **Postman** or **Thunderclient** and then create a new request like below
