Cold-email outbound system
Production sequencer for a consultancy: six-touch campaigns, reply detection and a partner approval loop.
The Challenge
A consultancy's outbound programme needed personal, research-based cold email sent from the founder's real address – with nothing going out unapproved and deliverability put first.
The Approach
The system imports prospect research and renders a six-touch sequence per prospect. Custom drafts are written in Claude Code from a research brief, then pass hard guardrail checks – claims, length, opt-out line, CAN-SPAM signature – before anyone can approve them. The client's two partners review in an Excel workbook that round-trips into the system. Approved emails go out over SMTP2GO with correct threading of follow-ups, and an IMAP poller detects replies and bounces and pauses those prospects automatically. A Flask dashboard shows the campaign and edits settings.
