Kersend

Email that just sends. The email and SMTP API for the EU.

Kersend is a developer-first email API and SMTP relay hosted entirely in the European Union, under EU law. Send transactional email over a clean REST API or the same SMTP you already use. No Amazon SES, no SendGrid, no US provider on the path.

Early access. This package reserves the @kersend scope. The Node SDK is in active development. Follow along at kersend.com.

Install

npm install @kersend/node

Quick start

import { Kersend } from '@kersend/node'

const kersend = new Kersend(process.env.KERSEND_API_KEY)

await kersend.emails.send({
  from: '[email protected]',
  to: '[email protected]',
  subject: 'Welcome',
  text: 'Thanks for signing up.',
})

Prefer SMTP. Point your existing setup at the Kersend relay and change four fields. Same logs, same webhooks.

What you get

• REST API and SMTP relay, one account
• Domain authentication with DKIM, SPF and DMARC
• Signed webhooks for sent, delivered, bounced, complained and suppressed events
• Automated IP warmup and suppression handling
• Logs and DKIM signing keys that stay in the EU
