Email address popup – blur prices

I'm running some tests on my website at the moment and I have built the screen in the image.

which contains:

  • Optional email address
  • Making the user feel that engaged with that request, without making them feel annoyed or that we are interrupting their task. I want to make the user feel exciting in this stage, that's why I implementing this view:

The user can feel that behind the popup we are showing blur prices and creating this kinda of expectation.

How shall I call this? I don't know how to name it and explain it to people.
