INVALID_EMAIL_ADDRESS, Email address is invalid:

Question

I am writing a single messaging class where I need to send some emails. There are emails field on the Account. On matching some conditions, I need to send emails to that particular person which is mentioned on the account emails field. I have put all emails in a String with a specific character as below:

//Class 
public class sendMailtoBank{

public static void sendInstantMail(Map<Id, Case> mapIdcse){

    Id bankteamId = System.Label.Foward_to_Bank_Team_Queue_Id;
    
    //Collected Account and its all related case.
    Map<Id, List<Case>> mapAccId_listcase = new Map<Id, List<Case>>(); 
 
    for(Case cse :mapIdcse.values()){
                                
        if(cse.AccountId!= NULL && cse.Forward_to_bank__c == true && cse.OwnerId == bankteamId){
            
            if(mapAccId_listcase.containskey(cse.AccountId)){
            
                List<Case> lst_cse = mapAccId_listcase.get(cse.AccountId);
                lst_cse.add(cse);
                mapAccId_listcase.put(cse.AccountId,lst_cse);                   
            }
            else {
                mapAccId_listcase.put(cse.AccountId, new List<Case> {cse});
            }
        }
    }
    
    List <Messaging.SingleEmailMessage> mailList = new List <Messaging.SingleEmailMessage> ();
    
    for(Account acc : [Select Id, Email_Dispute__c,Email_1_Dispute__c,Email_2_Dispute__c,Email_3_Dispute__c,Email_4_Dispute__c,Email_5_Dispute__c,
                                    Email_6_Dispute__c, name from Account where Id In :mapAccId_listcase.keyset()]){ 
        
        Messaging.SingleEmailMessage message = new Messaging.SingleEmailMessage(); 
            message.setSenderDisplayName('My Team');
            message.setReplyTo('[email protected]');
            message.setUseSignature(false); 
            message.setBccSender(false);
            message.setSaveAsActivity(false); 
            message.setSubject('List of Cases');

Error Below:

sendcaseMail: execution of AfterUpdate caused by: System.EmailException: SendEmail failed. First exception on row 0; first error: INVALID_EMAIL_ADDRESS, Email address is invalid: 

'[email protected]','[email protected]','[email protected]','[email protected]': [toAddresses, '[email protected]','[email protected]','[email protected]','[email protected]']

Class.sendMailtoBank.sendInstantMail: line 173, column 1 Trigger.sendcaseMail: line 4, column 1

Please let me know what is the issue here!

Answer 1

I think the array is initialized incorrectly - the whole collection of emails is treated as a single string.

Try collecting email addresses into a List, then use that list in .setToAddresses() method.

List<String> toAddresses = new List<String>(); 
toAddresses .add(acc.Email_6_Dispute__c);
message.setToAddresses(toAddresses);
