title: php cooldown timer for subscribe.php and sendmail.php
body: <p>Hello i just wanted to ask is there a way that i can add a cool down timer to my sites sendmail.php and subscribe.php file as i have done a test with Vega and it spams my email address with around 250+ emails which is very bad and will / can be abused very easily and hence i would like to add some sort of protection.</p>
  
  <p>I'm not sure what to currently try doing as im quite new to all this and some help would be very appreciated </p>
  
  <p>Thanks and i hope to fix this.</p>
