Description

Who is this template for?
This workflow template is designed for Sales and Customer Success professionals seeking alerts when potential high-value users, prospects, or existing customers register for a Discourse community. Leveraging Clearbit, it retrieves enriched data for the new member to assess their value.

How it works
Each time a new member is created in Discourse, the workflow runs (powered by Discourse's native Webhooks feature).
After filtering out popular private email accounts, we run the member's email through Clearbit to fetch available information on the member as well as their organization.
If the enriched data meets certain criteria, we send a Slack message to a channel. This message has a few quick actions: Open LinkedIn profile and Email member
