You Can go ahead with Workflow,ProcessBuilder or Flow to Achieve this Functionality

In WorkFlow Rule :
1.Set the Object -> Set when it will Fire -> put Condition if Language is 'English' and add more Conditons if need.
2.Actions : Choose Email Templete -> Choose Receipent Type : Public Group (Make Sure You Group Email id Should be null otherwise Email Send to the your Group Email not Group of Users).

Then you will go to Customization in the Apex.
1.Send an Email using Apex
2.Write the If conditions and get the Public Group Users from Queue

Send an Email Using Apex :

public class EmailSender {

public void sendMail() {
Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
mail.setSubject('This is the subject');
mail.setPlainTextBody('This is the body.');
Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });


private List<String> getEmailAddresses() {
List<String> idList = new List<String>();
List<String> mailToAddresses = new List<String>();
Group g = [SELECT (select userOrGroupId from groupMembers) FROM group WHERE name = 'MyPubGroup'];
for (GroupMember gm : g.groupMembers) {

User[] usr = [SELECT email FROM user WHERE id IN :idList];
for(User u : usr) {

return mailToAddresses;


Get the Public Group Users from Queue
You need to Write sub Query or Multiple Query
Here I put MultipleQuery to get the Public group Users of an Queue

All Queries are depened
1.SELECT Id, Name FROM Group where  Type = 'Queue' AND Name = 'Billing Support Queue' - Got your Queue
2.SELECT Id, Name FROM Group where Type = 'Group' Name = 'Billing Support Group' - Got your Group
3.SELECT Id, GroupId FROM GroupMember where GroupId = '00G7F000003YTH***'and Id = '0117F000001j3***'  - Got your Group id from the Queue
Hi Mohamed Ithris, I was trying to send an email from trigger to Public Groups using the above-mentioned approach. I am using a helper class for developing the trigger logic and created another method to get the Public Group emails. But, when the trigger fires I was getting few errors at setToaddresses. Can you help me with how to resolve this...
