Migrate from Resend

Drop-in 1:1 compatibility layer allowing instant migration from Resend with zero code refactoring.

Multivrs Mail is engineered as a seamless 1:1 drop-in replacement for Resend. You can migrate existing applications in less than 30 seconds without refactoring any payload shapes, error handlers, or method calls.

1. Install @multivrs/mail

Terminal

bun add @multivrs/mail

2. Update the Import Statement

Replace your Resend import statement with the exported compatibility module:

app/mailer.ts

// Replace this:
// import { Resend } from "resend";

// With this:
import { Resend } from "@multivrs/mail";

const resend = new Resend(process.env.MULTIVRS_API_KEY);

const { data, error } = await resend.emails.send({
  from: "onboarding@yourdomain.com",
  to: "user@example.com",
  subject: "Hello World",
  html: "<p>Congrats on sending your first email with Multivrs Mail!</p>",
});

Zero Code Changes Required

Sending: resend.emails.send(payload)
Retrieval: resend.emails.get(id)
Domains: resend.domains.create(), resend.domains.verify(), resend.domains.list()
API Keys: resend.apiKeys.create(), resend.apiKeys.list()

Dual Environment Variable Detection

The Resend compatibility client checks both MULTIVRS_API_KEY and RESEND_API_KEY in process.env, so you do not even need to change your production environment variable name immediately.
