MailChannels SDK for Node.js (Resend Alternative)

Source: Dev.to

The Idea

What if MailChannels had a modern Node.js SDK with a developer experience similar to tools like Resend?
MailChannels already provides a powerful API for sending emails and managing email infrastructure, but integrating directly means dealing with:

• Manual HTTP requests
• snake_case payloads
• Repetitive boilerplate code
• Less ergonomic workflows

The goal became to create a clean, TypeScript‑first SDK that feels natural for JavaScript developers.

Why MailChannels?

Both MailChannels and Resend offer a comparable free tier:

At higher volumes, MailChannels is cheaper:

The Goal of the SDK

The SDK isn’t meant to replace existing tools; it aims to improve the developer experience when using MailChannels by providing:

• A clean Node.js API
• TypeScript support
• Consistent naming conventions
• Simple email‑sending methods
• An ergonomic interface

Example usage

import { MailChannels } from "mailchannels-sdk";

const mailchannels = new MailChannels("your-api-key");

await mailchannels.emails.send({
  from: "Acme ",
  to: "user@example.com",
  subject: "Welcome!",
  html: "
Thanks for joining
",
});

The SDK

The SDK fully supports all features and operations available in the MailChannels API. It is actively maintained to ensure compatibility and to quickly add support for new API features as they are released.
