Hi Team,

Hi Srini,

The following code is for creating a new task when an opportunity is created.
  
trigger createTask on Opportunity (before insert, before update){ 
List<Task> tasks = new List<Task>(); 
List<Opportunity> Opps = Trigger.new; 
for (Opportunity Opp : Opps) {
Task tsk = new Task(whatID = Opp.ID, Ownerid = Opp.OwnerId); tasks.add(tsk); 
} 
insert tasks; 
}


The below code is for Sending an Email notification.
  
trigger SendEmailToAccount on Contact (after insert) {
    if(Trigger.isAfter){
        if(Trigger.isInsert ){ 
            //helper class for single email but bulk messages
            HelperContactTrigger.sendEmail(trigger.new);
        }
    }
}


Apex Class:

public with sharing class HelperContactTrigger {
    //static method
    public static List<Contact> sendEmail(List<Contact> contacts) {

        //query on template object
        EmailTemplate et=[Select id from EmailTemplate where name=:'Sales: New Customer Email'];

        //list of emails
        List<Messaging.SingleEmailMessage> emails = new List<Messaging.SingleEmailMessage>();

        //loop
        for(Contact con : contacts){

            //check for Account
            if(con.AccountId == null && con.Email != null){

                //initiallize messaging method
                Messaging.SingleEmailMessage singleMail = new Messaging.SingleEmailMessage();

                //set object Id
                singleMail.setTargetObjectId(con.Id);

                //set template Id
                singleMail.setTemplateId(et.Id);

                //flag to false to stop inserting activity history
                singleMail.setSaveAsActivity(false);

                //add mail
                emails.add(singleMail);

               //This will not send email to contact  
               emails.setTreatTargetObjectAsRecipient(false);
            }
        }
