Pay once · Build your own SMTP server in minutes
Infrastructure tuned obsessively for deliverability and speed — measured across billions of sends.
A complete sending platform — from authentication to analytics — without the enterprise bloat.
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.
A globally distributed sending network relays mail in under half a second, with intelligent queueing and retries built in.
Track opens, clicks, bounces, and spam complaints live. Drill into every event with webhooks and exportable logs.
TLS 1.3 in transit, encryption at rest, scoped API keys, SSO, and SOC 2 Type II compliance out of the box.
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.
Enter your server details and we do the rest — install, configure, and connect your domain automatically.
Provide your server's IP address, root username, password, and SSH port. That's all we need to get started.
We detect your server, then install and configure a complete SMTP engine automatically — no manual setup.
We link your domain and generate the DNS records (SPF, DKIM, DMARC). Publish them and you're ready to send.
