trustmailer

Rust-powered, nodemailer-compatible mail library — a native addon via napi-rs. One compiled binary, same API, runs unmodified on Node.js, Bun, and Deno.

Install

npm install trustmailer

Prebuilt binaries ship for macOS (x64/arm64), Linux (x64/arm64, glibc/musl), and Windows (x64/arm64) via optionalDependencies — no Rust toolchain needed at install time.

Usage

const { createTransport } = require("trustmailer");

const transporter = createTransport({
  host: "smtp.example.com",
  port: 587,
  auth: { user: "user", pass: "pass" },
});

const info = await transporter.sendMail({
  from: "Alice <[email protected]>",
  to: "[email protected]",
  subject: "Hello",
  text: "Hi Bob!",
  html: "<b>Hi Bob!</b>",
});
console.log("sent:", info.messageId);

Same code runs under Bun (bun run) and Deno (deno run -A, needs a .cjs/.mjs extension or a package.json with "type" set) — it's the same native addon underneath.
