Hi All,

trigger SendNotification on Savings_Risk_Checklist__c (After insert,after update) {

   Savings_Risk_Checklist__c SCS = trigger.new[0]; 
  if (Trigger.IsInsert || Trigger.IsUpdate) { 
    if(SCS.Savings_Checklist_Form_Status__c =='Proposal Submitted'|| SCS.Savings_Checklist_Form_Status__c=='Final From Submitted') {
       Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
          EmailTemplate et=[Select id from EmailTemplate where Name=:'Savings Risk Check List Proposal Submittion'];
          mail.setToAddresses(new List<String>{'putluruvishnu@gmail.com'});
          Messaging.SendEmailResult [] r = Messaging.sendEmail(new Messaging.SingleEmailMessage[] {mail});

Hi Satya,

You can not set custom object record id in setTargetObjectId method of Messaging.SingleEmailMessage. This id can be user , lead or contact so in your case you can set:
Also, You can write workflow or Process builder to send email.

Let me know if this helps you to solve your problem.

Hi Amol,

trigger SendNotification on Savings_Risk_Checklist__c (After insert,after update) {

  Savings_Risk_Checklist__c SCS = trigger.new[0]; 
 if (Trigger.isAfter && (Trigger.IsInsert || Trigger.IsUpdate)) { 
   if(SCS.Savings_Checklist_Form_Status__c =='Proposal Submitted'|| SCS.Savings_Checklist_Form_Status__c=='Final From Submitted') {
      Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
         EmailTemplate et=[Select id from EmailTemplate where Name=:'Savings Risk Check List Proposal Submittion'];
         mail.setToAddresses(new List<String>{'putluruvishnu@gmail.com});
         Messaging.SendEmailResult [] r = Messaging.sendEmail(new Messaging.SingleEmailMessage[] {mail});

The above trigger is working fine. but it's sending the email to Record owner also but i need only for the Receipients. also one more is i have a detail page link in my template. but in email i'm not receiving any link through email.

Could you please check.

To avoid sending email to record owner, you can use setTreatTargetObjectAsRecipient(false)

- Optional. If set to true, the targetObjectId (a contact, lead, or user) is the recipient of the email. If set to false, the targetObjectId is supplied as the WhoId field for template rendering but isn’t a recipient of the email. The default is true.
