Migration

Switching is a few lines of code.

Same fields, same idea. Install with npm install sendaro, set SENDARO_API_KEY, and change the call.

Before: Resend
import { Resend } from "resend";

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

const { data, error } = await resend.emails.send({
  from: "Acme <hello@yourdomain.com>",
  to: "maya@example.com",
  subject: "Reset your password",
  html: "<p>Use this link to choose a new password.</p>",
});
After: Sendaro
import { Sendaro } from "sendaro";

const sendaro = new Sendaro(); // reads SENDARO_API_KEY

const { id } = await sendaro.send({
  from: "Acme <hello@yourdomain.com>",
  to: "maya@example.com",
  subject: "Reset your password",
  html: "<p>Use this link to choose a new password.</p>",
}); // throws SendaroError on a non-2xx response

Not on Node.js? Call POST /api/emails with a bearer token from any language. See the API reference.

FAQ

Resend pricing and switching.

Yes. Resend's free plan includes 3,000 emails a month and sends at most 100 a day. Sendaro's free plan also includes 3,000 emails a month, refilled on the 1st, with no card needed.

Most of it is DNS. Add your domain in Sendaro, publish the DKIM, SPF and DMARC records, and wait for them to verify. The code change is usually a new import, a new environment variable and a different call name.

Yes. Each service signs with its own DKIM key, so both sets of records can sit side by side, and Sendaro shows you how to merge its SPF entry into the record you already have. Move one type of email first, like password resets, and switch the rest once you are happy.

At the list prices we compared, yes, at every matching volume. 50,000 emails a month cost $17 on Sendaro and $20 on Resend. Each extra 1,000 emails costs $0.79 on Sendaro and $0.90 on Resend Pro. Resend's Scale plans charge less per extra email, so at high volume compare the plan prices.

Yes. 3,000 emails a month, refilled on the 1st, with the full product and no card needed.

Today: attachments, multiple recipients in one request, and batch sends. If you rely on those, stay where you are for now. If you send one transactional email at a time, the switch is straightforward.
