A single Cloudflare Worker that turns cold-email replies into rich Slack alerts for any client — one deployment serving everyone, instead of a bespoke webhook each time.
Every new client wanted the same thing: a Slack ping the moment a prospect replied to a campaign. Building a one-off webhook integration per client meant repeating the same plumbing over and over and maintaining all of it forever.
One Cloudflare Worker that accepts a per-client path, looks up that client's Slack webhook from Worker secrets, and transforms the incoming reply event into a formatted Slack message — a header, structured fields, the quoted reply, and a button that opens the lead straight in the campaign tool. Adding a client is a single secret plus one webhook configuration.
