Overview

This API allows you to send emails via any SMTP server. You can provide all the required SMTP and email details either through the JSON request body or query parameters. It’s simple, fast, and public.

Perfect for:

• Serverless websites (like Vercel, Netlify, or Cloudflare Workers)
• Frontend apps where you don't want to expose your SMTP credentials
• Quick email testing without setting up a backend
• Contact forms on static sites

Accepts both JSON body and query parameters. You can also use GET requests for testing.
