kushagra_zryth · reddit · 2026-11-01
A developer who builds outbound/inbound sales agents shares five lessons: verify emails before sequences, prioritize first-reply speed over perfection, make agents leave checkable artifacts before claiming "done", use hard guardrails (send caps, banned phrases, human review for new contacts) instead of clever prompts, and write messages that sound human rather than template-personalized. The model is rarely what breaks—the plumbing around it is.
