How to get RecordTypeId without SOQL | Get RecordTypeId by Describe Call

Some time in code we need to get recordTypeId . For that generally we used SOQL like below :-

Id contRecordTypeId = [Select id from RecordType where sObjectType = 'Contact' and developerName ='NameOfRecordType' ].id ; 

You can try below Describe to get record Type Id without SOQL

Id contRecordTypeId = Schema.SObjectType.Contact.getRecordTypeInfosByName().get('NameOfRecordType').getRecordTypeId();

Record ID Prefix | Object Type from Record ID Prefix | Prefix of an Object in Salesforce.

We know there are two types of record-id are present in salesforce (18 digit -- Case Insensitive,15 digit -- Case Sensitive). Only 3 digit of ids represent object type .The following is a list of the Salesforce Standard Object ID prefixes


 Please check below post for more detail

If you want to get the Prefix of any object . Please try below code.

String keyPrefix = Account.sObjectType.getDescribe().getKeyPrefix();
System.debug('PREFIX--' + keyPrefix );

If you want to get the Object Name from RecordId then please try below code.

public class SchemaGlobalDescribeToGetObjectName
    public static String findObjectNameFromRecordIdPrefix(String recordIdOrPrefix)
  String objectName = '';
            String IdPrefix = String.valueOf(recordIdOrPrefix).substring(0,3); 
            Map<String, Schema.SObjectType> gd =  Schema.getGlobalDescribe(); 
            for(Schema.SObjectType stype : gd.values())
                Schema.DescribeSObjectResult r = stype.getDescribe();
                String prefix = r.getKeyPrefix();
                if(prefix!=null && prefix.equals(IdPrefix))
                    objectName = r.getName();
                    System.debug('Object Name! ' + objectName);
        }catch(Exception e){
        return objectName;

If you want to Get the Object prefix by Workbench then please try below step :-

The easiest way to find out which key prefix maps to which object is by using a tool like the workbench . After you log into workbench, go to and pick an object from the pick list.

Step 1 :- Login in to Workbench

Step 2:- Info > Standard & Custom Objects 

Step 3:- Then select your object

SingleEmailMessage Vs MassEmailMessage | Send Email by Apex

SingleEmailMessage Vs MassEmailMessage

Multiple recipients?YesYes
Personalized body?Yes (single body only)Yes
Special permission needed?NoYes, has to be enabled
Merge fields?YesYes
Personalized merge fields?Yes (only one record at a time)Yes
Template possibilities?Text/HTML/Visualforce/Custom TemplatesText/HTML/Custom Template


Single emails are like regular individual emails that may go to one or more addresses (to/cc/bcc), but each of these emails has the same body

Messaging.SingleEmailMessage message = new Messaging.SingleEmailMessage();
message.toAddresses = new String[] { '', '' };
message.optOutPolicy = 'FILTER';
message.subject = 'Opt Out Test Message';
message.plainTextBody = 'This is the message body.';
Messaging.SingleEmailMessage[] messages =   new List<Messaging.SingleEmailMessage> {message};
Messaging.SendEmailResult[] results = Messaging.sendEmail(messages);

if (results[0].success) 
    System.debug('The email was sent successfully.');
} else 
    System.debug('The email failed to send: ' + results[0].errors[0].message);
Please check below post to see all other method 


Mass emails typically go to a large number of addresses (currently capped to 250 per email), with personalized message bodies.
public void SendEmail()
 List<contact> lstcon=[Select id from contact limit 2];
 List<Id> lstids= new List<Id>();
 for(Contact c:lstcon)
 EmailTemplate et=[Select id from EmailTemplate where name = 'EmailTemplatename' limit 1];
 Messaging.MassEmailMessage mail = new Messaging.MassEmailMessage();
 mail.setSenderDisplayName('System Admin');
 Messaging.sendEmail(new Messaging.MassEmailMessage[] { mail });
