Land in the inbox
Routing optimized per provider, with live events confirming every delivery, open and click.
No credit card required - Setup in under 5 minutes
FOR DEVELOPERS
An API your engineers will actually like
Idiomatic SDKs, predictable responses, and webhooks for every delivery event.
- REST + SMTP. Modern API for new builds, drop-in SMTP relay for legacy systems.
- Event webhooks. Delivered, opened, clicked, bounced, complained - streamed in real time.
- Idempotency keys. Retries never double-send an invoice.
import { Ackuna } from '@ackuna/sdk';
const ackuna = new Ackuna(process.env.ACKUNA_API_KEY);
await ackuna.emails.send({
from: 'billing@yourapp.com',
to: 'customer@gmail.com',
subject: 'Your June invoice',
html: invoiceTemplate,
tracking: { opens: true, clicks: true },
});
// -> { id: 'em_8Kf2...', status: 'queued' }PLATFORM
Everything serious senders need

CUSTOMERS
Teams switch for the reliability
"We migrated off two tools - one for receipts, one for the newsletter. Deliverability went up and our invoices stopped landing in spam."
"Setup genuinely took an afternoon. DNS records, one API call, done. The event webhooks saved us building our own tracking."
"Finance liked one bill, legal liked one data processor, and I liked that my campaign opens stopped being a mystery."
