Email your users actually receive.

Nextsend is the independent transactional email platform from Nexthome Labs — a clean API, an SMTP relay, and deliverability tooling that treats your sender reputation like production infrastructure.

Everything between your code and the inbox

Transactional email API

One POST sends a message. Idempotency keys keep retries safe, and every send is tracked end to end.

SMTP relay

Point your existing apps at our SMTP endpoint with scoped credentials per environment.

Sending domains

Guided SPF, DKIM, and DMARC setup with live DNS health checks on every domain you add.

Analytics

Delivery, bounce, and complaint rates per domain, per stream, per day.

Event webhooks

Deliveries, bounces, and complaints pushed to your endpoints with signed payloads.

Reputation guardrails

Suppressions, blocklist monitoring, and DMARC reports keep your sender reputation intact.

Templates & logs

Design reusable templates and search full message logs whenever you need answers.

Scoped API keys

Production and test keys with per-project limits, rotated without downtime.
