SingleEmailMessage with targetObject and templateId

Hi 

My scenario is that I would like to notify all contacts for an account about a new custom record being created. There is no relationship between the custom object and contacts. 

The code that I am using allows me to send the email but it is in the contact context and I am not certain how to set a SentToAddress and a TargetObjectId. 
  
public class SendEmailTemplatesToAccountContacts {

  @InvocableMethod
  public static void sendEmail(List<Account> acc) {
 
  Shipment_Order__c so = new Shipment_Order__c ();
    String sourceAccountId = String.valueOf(acc[0].Id);
    List<Messaging.SingleEmailMessage> emailsToSend = new List<Messaging.SingleEmailMessage>();
    List<Contact> contactsToEmail = [SELECT Id
                                     FROM   Contact
                                     WHERE  AccountId = :sourceAccountId];
    Id templateId = [SELECT Id, Name
                     FROM   EmailTemplate 
                     WHERE  Name = 'New Shipment Notification Supplier'].Id;

    for(Contact con: contactsToEmail){
    

      Messaging.SingleEmailMessage email = new messaging.SingleEmailMessage();
      email.setTemplateId(templateId);
      email.setTargetObjectId(con.Id);
      email.setSaveAsActivity(true); //or true if you want to save as an activity
      email.setSenderDisplayName('Sender Display Name'); //Here if you want to change the sender name
      emailsToSend.add(email);

    }
    Messaging.sendEmail(emailsToSend);
  }
  
}

Hi Rahul

That made a lot of sense, I have adjusted the code but now I am getting an error that the TargetObjectId is missing.  
public class SendEmailTemplatesToAccountContacts {

  @InvocableMethod
  public static void sendEmail(List<Account> acc) {

    Shipment_Order__c so = new Shipment_Order__c ();
    String sourceAccountId = String.valueOf(acc[0].Id);
    List<Messaging.SingleEmailMessage> emailsToSend = new List<Messaging.SingleEmailMessage>();
    List<Contact> contactsToEmail = [SELECT Id, Email
                                     FROM   Contact
                                     WHERE  AccountId = :sourceAccountId];
    Id templateId = [SELECT Id, Name
                     FROM   EmailTemplate 
                     WHERE  Name = 'New Shipment Notification Supplier'].Id;

    for(Contact con: contactsToEmail){
    
    

      Messaging.SingleEmailMessage email = new messaging.SingleEmailMessage();
      List<String> sendTo = new List<String>();
      sendTo.add(con.Email);
      email.setTemplateId(templateId);
      email.setWhatId(so.Id);
      email.setTargetObjectId(so.Id);
      email.setTreatTargetObjectAsRecipient(False);
      email.setToAddresses(sendTo);
      email.setSaveAsActivity(true); //or true if you want to save as an activity
      email.setSenderDisplayName('TecEx Support'); //Here if you want to change the sender name
      emailsToSend.add(email);

    }
    Messaging.sendEmail(emailsToSend);
  }
  
}
