Platform
Engineered for deliverability.
Every detail — from routing to suppression — designed so your sending reputation stays clean.
Per-tenant IP pools
Transactional and marketing isolated. Shared, dedicated or warm-up mode — switchable from the portal.
Centralised suppression list
Hard bounces (DSN 5.x.x) and FBL ARF complaints blocked automatically, at tenant and platform level.
Reactive auto-throttling
If an ISP defers, we drop volumes and re-open as reputation recovers. No manual ops needed.
Per-tenant isolation
Each tenant routed through a dedicated socketmap. Your reputation never depends on a noisy neighbour.
Automatic warm-up
Per-pool warm-up curves. smtp_destination_rate_delay & concurrency_limit tuned daily.
Multi-server by design
Data plane / control plane architecture. MTAs keep running locally even if Cloudflare is down.
Built for serious senders
SaaS, e-commerce, fintech — anything that must arrive.
Transactional emails, order confirmations, password resets, weekly digests, opt-in newsletters.
