Customer domain first
Send from domains customers control.
Crusher uses our SES backend, but customers configure and verify their own sending domains so identity, DKIM, and reputation stay clear.
SES-backed communications control plane
B2B email operations for messages your contacts expect.
Crusher helps teams send lifecycle, funnel, and pipeline messages from customer-verified domains with safe ramps, billing-aware operations, and delivery feedback loops.

Approvals, ramps, and suppression.
Every campaign is staged with DNS readiness, send-plan approval, SES events, bounces, complaints, and usage billing in one control plane.
