Core features

Everything you need. Nothing you don't.

Instant Delivery API

Single endpoint for transactional, bulk and batch emails. Send one or one million with the same call signature.

Real-time Analytics

Opens, clicks, bounces, spam reports and unsubscribes. Stream events via webhooks or query our metrics API.

Advanced Auth

DKIM, DMARC, SPF auto-configuration. Custom domain verification in under 5 minutes. IP warm-up included.

Template Engine

Handlebars, Liquid, MJML and React Email supported. Version control, A/B testing and preview environments.

Smart Routing

Geo-based routing, failover pools and priority queues. Your transactional traffic never shares infra with bulk.

SDK + SMTP Bridge

Official SDKs for Node, Python, Go, PHP, Ruby. Drop-in SMTP relay for legacy apps. Zero code changes required.

REST API

Designed for devs, not dashboards.

Clean, predictable REST endpoints. Idempotent keys, cursor-based pagination, structured errors with machine-readable codes. Every response includes trace IDs for debugging in production.

Infrastructure

Built to survive production.

Dedicated IPs

Your reputation, your IPs. Automated warm-up schedules. Shared pools available for smaller volumes.

Global Edge

6 regional data centers across US, EU and APAC. Automatic latency-based routing with geo-failover.

Event Streaming

Webhook delivery with automatic retries, dead-letter queues and per-event HMAC signatures for security.

Multi-tenant Isolation

Strict queue and rate isolation per account. Your sends never affect another tenant's delivery or reputation.

Pricing

Honest pricing. No surprises.
