I made this service ages ago. It uses PHP so that you can send emails immediately from your game without the user noticing anything… This is a copy of my post at the GMC:

<center><b>Game Maker Mail</b>

Dear users of the GMC.
I hope some of you will find this useful. I leave it to you to develop areas of use. What it does, is sending emails. It does not, like the D&, open some other e-mailing program, it let's you send the mail. The possibilities to what to use this for i wide, email programs, alarm and notifying is some examples.

It is easy to use, this is how to call it: </center>

CODE:

mail("username","password","subject","message","reciever@reciever.com";

You can get username and password from our homapage. It is for security reasons that we have made this system, but it's easy and quick.
