>We are letting user know that u have thrown email to someone and we also let user know how is going to contact them.
This is good, but you cannot stop the email from opening and the user
needing to send it. This is, as I said, fundamental to security and
cannot be switched off.
>I tried using HTTP request but it still opening email option to send mail.
This suggests you did not do it right, because when you use http, no
mail is sent locally. Can you describe what you do?
HTML cannot silently send an email either.
that we can suggest an equivalent if there is one.
