Where a point solution breaks
- Sequencing logic is templated — it can't branch on your actual ICP signals or deal stage without manual rule-building
- Deliverability (domain rotation, warm-up, throttling) is handled generically across all customers, not tuned to your specific sending patterns
- Reply handling and CRM sync are bolt-on integrations, not native — a reply can sit unrouted until someone checks the tool's own inbox
Cold email tools are built to send at volume, not to reason about a specific reply. An embedded engineer builds the sequencing and reply-routing logic as code that plugs into your actual CRM, with sending infrastructure tuned to your domain's real reputation.
