Your contactList is not having records thats why its giving error. This will resolve your error.

Hi,

 

List index out of bound exception is shown because you are trying to use the list and referring an id from it.

So, your code should be altered like the following,

 

public PageReference send(){

   List<EmailTemplate> TemplatesList = [Select Id, Name, IsActive, Folder.Name,subject From EmailTemplate

                                                                   where Folder.Name ='DRM Email Templates' and id = :emailtemplateid];

   if(TemplatesList.size() > 0){

     for(Templates t : TemplatesList){
         Messaging.singleEmailMessage email = new Messaging.singleEmailMessage();
         email.setToAddresses( toAddresses );
         email.setTemplateID(t.Id);
         email.settargetObjectId(contactList[0].Id);
         Messaging.SendEmailResult [] r = Messaging.sendEmail(new Messaging.singleEmailMessage[] {email});

      }

   }

else{

     //Your error message to show here

}

return null;

}

 

Hope so this helps you...!
