I want to create a separate email from my email address and send out the link with instructions

Lastly, under publish, I need to add instructions to the form but I want to create a separate email from my email address and send out the link with instructions. Can I do this?

You may send the link along with the instructions from your own email client.

Do you want to add the customized instructions while assigning the form to the people? If yes, then you may be able to add the custom message as shown:

Let us know if you have further questions.
