The platform
One platform. Five surfaces.
One platform. Five surfaces.
Built end-to-end.
Infrastructure, campaigns, deliverability, analytics, and a developer API — engineered as one system, not five acquired ones.
Multi-tenant SMTP infrastructure that doesn't crumble.
Per-tenant queues with priority weights, automatic VMTA pool warmup, IP-level throttling, RFC-compliant bounce classification, and zero shared fate between customers.
- Direct MX delivery + intelligent retry curves
- Hot/warm/cold IP pools with traffic mixing
- MTA-STS, TLS-RPT, ARC seal generation
- Per-domain rate limiting with burst tokens

Multi-tenant
Workspace isolation, per-tenant SSO, audit logs, role-based access.
VMTA pools
Group IPs by use case. Auto-warmup, automatic pool routing.
DKIM, SPF, DMARC
Generated, validated, monitored. Aggregate reports parsed for you.
Live queue inspection
