Why switch
They send email. Sendarix controls delivery.
Sendarix is the email delivery control plane with the relay infrastructure behind it — where you define routing policy, isolate tenant blast radius, monitor every event, and recover before users notice.
Shared reputation pool
no control planeOne abusive tenant poisons the pool — every customer degrades.
Isolated with Sendarix
blast radius containedThe bad tenant is quarantined to its own pool — everyone else stays healthy.
Category shift
A new layer, not another sender
Classic ESPs optimize for sending volume. Sendarix optimizes for infrastructure control — the operations your platform team needs when email is the product.

The control loop
Route. Isolate. Monitor. Recover.
Four operations form a continuous control loop around your most critical email.
Route by policy
Send every message through the right relay pool, IP set and stream based on tenant, domain, message type and live path health.
02 / ISOLATEIsolate blast radius
Wall off tenants, domains and traffic classes so one bad sender can never contaminate everyone else’s reputation.
03 / MONITORMonitor everything
See every send, deferral, bounce and complaint in a live event timeline — deliverability becomes observable, not mysterious.
04 / RECOVERRecover automatically
Detect degradation and reroute critical streams to healthy relay paths before a deferral turns into a support ticket.
