that's great stuff. quick suggestion: if you're collecting the first names of your users, you should make sure to include their name when addressing that email. it does wonders to make it seem more personalized.
smaller suggestion: considering the tone in the email, i think the ask could be a bit more informal than "please respond..." <-- sounds very robot-like. i would say "if so, let us know the best number to reach you :) "
