E-mail Validator Widget: How to use custom Sender Email address?

hello - when a person verifies his email - is there a way to make that the verificaiton email was sent from my email?

I am not sure if I have understood your question correctly. Do you mean to say that the verification email which is sent from "E-mail Validator"  widget?

Unfortunately it is currently not possible to change the sender name and email of the email validator widget. I am creating a feature request ticket and forwarding it to our backend team. Though we cannot provide an ETA on this but we will get back to you on this as soon as we have any update from them.
