Hello,

I am executing below code in an Apex Batch
The Query returns a list of 200 records and stores it in scope. 

My Code is getting executed successfully, even after checking debug logs, there is no exceptions or any error. But the problem here is mails are getting delivered to only first few records in the list and none of the others are receiving the mails. 

I went to workbench and checked the mail limits are decreasing from 1000 to 800. But only few ppl are getting the mails and others aren't. Below is the sample code.

 

List<Messaging.SingleEmailMessage> mails = new List<Messaging.SingleEmailMessage>();

for(Service_Resource__c sr : (List<Service_Resource__c>)scope) {
Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();
                if(owa.size()>0){
                       email.setOrgWideEmailAddressId(owa[0].Id);    
                }
                else{
                    email.setSenderDisplayName('NoReply-ActNow');
                }
                email.setSubject(htmlsubject1NonSFUsers);
                email.setToAddresses(new String[] {sr.Email__c});
                email.setSaveAsActivity(false);
                email.setHtmlBody(htmlbody1NonSFUsers);
                email.setTemplateId(nonSFUsersEmailTemplate.Id);
                mails.add(email);
}
if(mails.size()>0){
      Messaging.sendEmail(mails);
}

Requesting you to help me out here to find out why the emails are not getting delivered to everyone even though the email limits are not over.

Thank you
