const resend = new Resend(process.env.RESES_KEY);
// point the SDK at reSES:
// RESEND_BASE_URL="https://api.reses.io"

await resend.emails.send({
  from: "you@mail.acme.dev",
  to: "dana@example.com",
  subject: "Hello",

Product

Everything Resend has — plus the part it doesn't

A complete sending API with the observability layer teams actually need.

Observability, built in

Every SES event — Send, Delivery, Open, Click, Bounce, Complaint — in time-series charts and per-message timelines. The thing Resend keeps shallow.

Drop-in Resend API

Keep the Resend SDK. Change one base URL.

Bring your own SES

Send through your AWS account. Your reputation, your rates.

Auth done right

Automatic DKIM, SPF and DMARC on every domain.

Workspaces & teams

Separate domains, keys, and members per workspace.

Webhooks & events

Real-time, signature-verified event delivery to your stack.

How it works

Live in three steps

From AWS key to observed send in minutes.

Connect your SES

Add an AWS IAM key. reSES sends through your account — nothing changes about your deliverability.

Point the SDK at reSES

Set one base URL. Your existing Resend code sends through reSES unchanged.

Watch every event

Opens, clicks, bounces and complaints stream into your dashboard in real time.

Pricing

Simple, usage-based pricing

You only pay reSES — SES charges land on your own AWS bill. Placeholder tiers; final pricing TBD.
