Build website that can enter user information and send email to users.

I am looking a website that can accept user information and store securely , user information would be like this. User name , phone number, email address, school , date of birth, addresss. It should also have the capability to send automated email to user. it should also have the capability to search on the basis of phone number , email or date of birth. As this information is personal , i am looking high level secruity. Thanks Ali
