What it does

You feed in a webhook and it comes out the other side as a sent LinkedIn message or email, personalised to the prospect, qualified against your ICP, and written in your brand voice. No manual research. No copy-paste. No delay.

Perplexity runs the research pass. Claude scores the lead and writes the opener. Expandi delivers it. The whole chain runs in under three minutes per prospect. The default stack is opinionated because it works. Every step has six alternatives if your preferred tool sits elsewhere.

This template is part of the Buttermilk Lead Engine and the Arcus Outreach System. Both run it at volume, daily.
