The challenge
Where it started
Outbound tools get sales teams blacklisted.
What we built
The build
- Sequence Intelligence: nine layers (timing, deliverability, personalisation, intent, conversation, fatigue, conflict resolution, outcome, governance) under a Guardrail
- Sequence Risk Score with healthy/elevated/risky/dangerous bands; dispatcher enforces min(daily cap, guardrail cap)
- Vera upgraded from command bar to agent runtime: plan → confirm → execute → independent verifier
- Multi-mailbox rotation, recipient-local send windows, advisory-lock dispatcher with SKIP LOCKED
- Razorpay billing with webhook-replay and signature fixes; partner program and portal
- Hardening: request-log redaction, SSRF-guarded fetch, CSV formula-injection guard, hashed tokens
Outcome
Where it is now
01
324/324 pages and 73/73 browser tests clean
02
Owner-side QA agents (sentinel, vera-eval, testkit) running nightly
03
Positioned as 'outbound that cannot get you blacklisted' with agencies and affiliates as channels
