Please guide me to do the correct things.
do you mean contact form ?
Yes…I already mentioned it…
Could you make your question a bit clearer please?
When I create a signup form it needs to set an email address to forward email. For this reason can I ask to the client for provide his email address?
yes you can of course without email how can buyer will receive message after creating it
So long as you ask for it on the order page it’ll be fine.
Thanks for your information.
