Change E-Mail address only after DOI confirmation

Dear Community,

we use infusionsoft to manage the users of our software platform.
In our software platform, we want to offer our users the opportunity to change their e-mail address.
However, we do not want to allow them to just change their e-mail address - as there’s the risk of typos etc.; So, our plan is this:

  1. User asks to change his e-mail address in our platform (easy)
  2. User receives a DOI-Confirmation-Mail via Infusionsoft, to his NEW e-mail address
  3. Only after confirming the DOI-Confirmation-Mail, the old e-mail address is replaced by the new one.

How can we do that?

Thank you very much!
David
