Hi Deepak,

Please find the trigger code below -

Assumption:

Project Object: Project__c
Relation with Account is Mater-Detail
Custom Field on Project Object: Group_email__c
  
trigger ProjectTrigger on Project__c (after insert) {
	List<String> emailAddresses = new List<String>();
	Map<Project__c, List<String>> projectEmailAddressMap = new Map<Project__c, List<String>>();
	
	List<Messaging.SingleEmailMessage> allMessages = new List<Messaging.SingleEmailMessage>();
	
    for(Project__c singleProject : Trigger.New){
    	Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();
		//Insert your subject here
    	email.setSubject( 'Test' );
    	String[] toAddresses = singleProject.Group_Email__c.split(',', 0);
    	email.setToAddresses( toAddresses );
		
		//insert your email body content here
    	email.setPlainTextBody( 'Test Body' );
    	
    	allMessages.add(email);
    }
    
    if(allMessages.size() > 0){
    	Messaging.SendEmailResult [] r =
            	Messaging.sendEmail(allMessages); 
    }
}

I would suggest you to learn Apex Trigger by going through the Trailhead module @ https://developer.salesforce.com/trailhead/module/apex_triggers

  // Before Insert Trigger
  public void OnBeforeInsert(list<Customer_Projects__c> Cusprojectlist){ 
    if(Cusprojectlist!=null && Cusprojectlist.size()>0){
