Hi,
I want to make a system where after an email is received to a specific account send an email with a form. My actual idea is that with some of the information captured from the form use it as a reference for pulling out data from a salesforce record and then using that data for some further validations. I am struggling in how to get the record ID.

For example that with an email (that would be captured from the Form sended to the user), being able to retrieve and capture some User Data from sales force for the specific record that contains the submitted email in the form. Is that possible? What is the best way for doing so?
