Hello @bandreas3
Yes, of course. That’s possible. Assuming the field to prefill is the fieldname1. Please insert a calculated field in the form to be used as an auxiliary (you can hide it and exclude it from the form submission by ticking a couple of checkboxes in its settings) and enter the following equation:
getField(fieldname1|n).setVal(getURLParameter('email', ''));
Learn more about the getField operation in the “Managing Fields Operations” module by visiting the following link:

And the getURLParameter in the “URL Operations” module:

Best regards.
