Features

Everything you need to ship email

A complete sending platform — from authentication to analytics — without the enterprise bloat.

Inbox-first deliverability

Automatic SPF, DKIM, and DMARC alignment, dedicated IP pools, smart warm-up, and real-time blocklist monitoring keep your reputation pristine so messages reach the inbox — not spam.

Sub-second relay

A globally distributed sending network relays mail in under half a second, with intelligent queueing and retries built in.

Real-time analytics

Track opens, clicks, bounces, and spam complaints live. Drill into every event with webhooks and exportable logs.

Enterprise security

TLS 1.3 in transit, encryption at rest, scoped API keys, SSO, and SOC 2 Type II compliance out of the box.

Developer-first API & SMTP

Drop-in SMTP credentials work with any stack, or use our clean REST API and SDKs for Node, Python, Go, Ruby, and PHP. Templating, scheduling, batch sends, and idempotency keys are all first-class.

How it works

Your own SMTP in three steps

Enter your server details and we do the rest — install, configure, and connect your domain automatically.

1

Enter your server

Provide your server's IP address, root username, password, and SSH port. That's all we need to get started.

2

Auto-build the SMTP

We detect your server, then install and configure a complete SMTP engine automatically — no manual setup.

3

Connect domain & DNS

We link your domain and generate the DNS records (SPF, DKIM, DMARC). Publish them and you're ready to send.
