Salesforce has no built-in Email-to-Lead feature, but you can build Email-to-Lead using Salesforce Flow: let Email-to-Case turn incoming sales emails into cases, then a record-triggered flow on Case creates a Lead from the sender’s name, email and phone and deletes the case. In my test, two emails sent to the sales address became two leads within the same save.
I built and ran this flow in a Salesforce Developer Edition org. Below are the exact entry conditions, the formulas that split the sender’s name and pick a company, the real leads it created, and what to watch out for before you use it in production.
