How to redirect form to a separate form?

I have 3 processes and each process has been done on 3 different forms. After the applicant completes process one I want to add a button saying "Proceed to step 2" (I guess this will be the "next" button that I should rename) and step 2 is on another form. Same procedure for step 3.

How do I do to link the three steps together? 

At the end, I only want "step 3" responses to be submitted to my email address.

Thanks for helping.

Please check the below steps to link your form to another form or another page:

1. Click the "Thank You" button in toolbar

2. Click the "Redirect to a external link" button in the thank you page wizard

3. Enter the URL of another form and click the "Save Changes" button

You can also send your form data to another form. Please  check the below guide which explains, How to Automatically Pass Form Data to Another Form:

If you do not want to receive the form submission notification email of  your first form and second form, you would require to delete form Email Notification of your first two forms, and then save your form. Please take a look at the following guide:
