Quickstart

From zero to delivered in five minutes.

No sales call, no onboarding queue. Add a domain, grab a key, send — and watch the events arrive.

  1. 01

    Add your domain

    One call returns the exact DKIM, SPF and DMARC records to publish — plus a custom MAIL FROM. Paste them once and you own your reputation.

    POST /v1/domains
  2. 02

    Grab your API key

    Scoped keys for send, read and admin. Test keys simulate delivery so you can wire everything up before going live.

    POST /v1/keys
  3. 03

    Send your first email

    A single POST — or batch thousands in one call. Idempotency is built in, so retries never send twice.

    POST /v1/send
  4. 04

    Watch it land

    Every message carries a full event timeline. Stream delivered, opened, bounced and complained events straight to your webhook.

    GET /v1/messages/{id}
One endpoint

Send from any stack in one call.

Use the language you already ship in. Idempotency keys are generated for you, so retries are always safe.

Why Sendara

Everything you need to run production email.

The boring infrastructure that makes email reliable — authentication, retries, events and reputation — handled, so you can ship.

Inbox-grade deliverability

Authenticate your own domain in minutes — we generate DKIM, SPF, DMARC and a custom MAIL FROM. Automatic suppression handling keeps your sender reputation clean.

Built for engineers & agents

One endpoint, required idempotency keys so retries never double-send, and a sandbox that drives delivered@, bounced@ and complained@ outcomes end to end.

Fast, then faster

Send one email or batch thousands in a single call. Each item succeeds or fails independently, in request order — partial success is normal.

See every event

A complete event timeline per message, plus webhooks for delivered, opened, bounced and complained — in real time, not in a daily digest.

Scoped, secure keys

send / read / admin scopes, one-time secret reveal, and instant rotation. Separate live and test keys so nothing leaks between environments.

Honest pricing

$0.50 per 1,000 emails. No free tier, no metered surprises — just a fair price for teams shipping real product.

Deliverability

Built to land in the inbox — not the spam folder.

Deliverability isn't a dashboard metric you check after the fact. It's authentication, reputation and feedback loops working from your very first send.

  • Your domain, fully authenticated

    Add a domain and get ready-to-paste DKIM, SPF and DMARC records plus a custom MAIL FROM. Re-verify any time with a single call.

  • Reputation protection on by default

    Hard bounces and complaints are suppressed automatically. Manage the suppression list over the API so you never re-send to a dead address.

  • Test the whole path before you ship

    Sandbox keys simulate real outcomes — send to delivered@, bounced@ or complained@ and watch your webhook handlers fire, without billing or real mail.
