html button to send email

Question

How do I send an email with specified initial values for the headers subject and message from a button in html, such as this

Answer 1

You can use an anchor to attempt to open the user's default mail client, prepopulated, with mailto:, but you cannot send the actual email. *Apparently it is possible to do this with a form action as well, but browser support is varied and unreliable, so I do not suggest it.

HTML cannot send mail, you need to use a server side language like php, which is another topic. There are plently of good resources on how to do this here on SO or elsewhere on the internet.

If you are using php, I see SwiftMailer suggested quite a bit.
