Get a Slack alert when a high-value lead emails you

Whenever a new email arrives in your Gmail inbox, the AI works out who wrote it and which company they work for, from the signature and the sending domain rather than a free mailbox address. Newsletters, receipts and vendor pitches come back with no company, and mail from your own colleagues and replies in a conversation already under way are skipped, so no research is spent on them. For a real company, the web is researched for what it does, its size, funding, customers and recent changes, and the lead is scored from 1 to 10 against what you sell, weighing what the email asks for as heavily as the company's size.

A score at or above your bar becomes a Slack direct message naming the company, the score, the reason, what the research found and a link to the email. Lower scores are only noted in the run, and an answer from the AI that cannot be read scores zero, so a bad answer can never fire a false alert.

You need Gmail, Anthropic, Perplexity and Slack connected, and three things you are asked for when you add it: who gets the alerts (the Slack user ID), what you sell and to whom, and your own email domain so mail from colleagues is skipped.
