I designed an educational app to be used by my students.
It has a one time signup page, the first time a student registers his email to start using my app.
What I want is to receive from him/her an email/SMS without opening any email client program or SMS program and without the permission from him/her to send me the message that he/she registered and where the message includes the email of the student used in the registration process.
Can we do it?
Can you send me a sample simple project that does this task Please?
Thank you in advance for your cooperation
