Complete tutorial of Email services in Salesforce with simple step by step example

What is an Email service in Salesforce?

Email services are automated processes that use Apex classes to process the contents, headers, and attachments of inbound email.

You can associate each email service with one or more Salesforce-generated email addresses to which users can send messages for processing.
The general template to create the apex class for the email services is:

How Email Services works in Salesforce
How Email Services works in Salesforce

global class myHandler implements Messaging.InboundEmailHandler {
	  global Messaging.InboundEmailResult handleInboundEmail(Messaging.InboundEmail email, Messaging.InboundEnvelope envelope) {
		  Messaging.InboundEmailResult result = new Messaging.InboundEmailresult();
          return result;

Example of Email Service – Creating Contact from email
Presumption –

  • Subject should contain word “Create Contact”
  • Body contains only Contact Name.

Apex Code with test method:

 * Email services are automated processes that use Apex classes
 * to process the contents, headers, and attachments of inbound
 * email.
global class CreateContactFrmEmail implements Messaging.InboundEmailHandler {

    global Messaging.InboundEmailResult handleInboundEmail(Messaging.InboundEmail email,
    Messaging.InboundEnvelope envelope) {

        Messaging.InboundEmailResult result = new Messaging.InboundEmailresult();

		String subToCompare = 'Create Contact';

			Contact c = new Contact();
			c.LastName = email.plainTextBody;
			insert c;

                // Save attachments, if any
        	for (Messaging.Inboundemail.TextAttachment tAttachment : email.textAttachments) {
          	Attachment attachment = new Attachment();

          	attachment.Name = tAttachment.fileName;
          	attachment.Body = Blob.valueOf(tAttachment.body);
          	attachment.ParentId = c.Id;
          	insert attachment;

        	//Save any Binary Attachment
        	for (Messaging.Inboundemail.BinaryAttachment bAttachment : email.binaryAttachments) {
          	Attachment attachment = new Attachment();

          	attachment.Name = bAttachment.fileName;
          	attachment.Body = bAttachment.body;
          	attachment.ParentId = c.Id;
          	insert attachment;

	result.success = true;
        return result;

    static testMethod void testCreateContactFrmEmail() {
    	Messaging.InboundEmail email = new Messaging.InboundEmail() ;
        Messaging.InboundEnvelope env    = new Messaging.InboundEnvelope();

        email.subject = 'Create Contact';
        email.plainTextBody = 'FromEmail';
        env.fromAddress = '';

        CreateContactFrmEmail creatC = new CreateContactFrmEmail();
        creatC.handleInboundEmail(email, env );

After creating the above Apex class, click Your Name | Setup | Develop | Email Services.

  • Click New Email Service to define a new email service.
  • Select above apex class, add email address from where to accept the request and activate the service.

After filling the form, click on “Save and New Email Address”

Email Address Information - Salesforce

Note: The domain name in Email address must qualify the domain name entered at “email services” in first step. For example : we have entered “” in first step that means it will accept the email address only from the and that’s why in second step I have used email address displayed in screen shot.
After all the above steps, one email address is generated by the salesforce. Send the email to that address with subject line “Create Contact” and contact name in email body.
In the above tutorial, I have used very simple example just to demonstrate that how the email services works in the salesforce.

Governance limit of Email services in salesforce:
Salesforce limits the total number of messages that all email services combined, including On-Demand Email-to-Case, can process daily. Messages that exceed this limit are bounced, discarded, or queued for processing the next day, depending on how you configure the failure response settings for each email service. Salesforce calculates the limit by multiplying the number of user licenses by 1,000, up to a daily maximum of 1,000,000

    • JitendraZaa

      Can you please try this - 
       email.setSubject(‘Test Email’);
      instead of
       email.setSubject( subject );

        Hello Jithendra,

        I have a scenario like want to accept emails only and if any other email comes which should have or or any other domain name with #Support#. How can I achieve this, where can I validate this means in apex end or configuration ‘Accept Email Form’ section?

        Please suggest.

        Thanks in Advance


        • JitendraZaa

          Hello Kumar,
          It cannot be done in “Config” section because your requirement is very advance. So better to use inside Email Service Apex class only.

    hi i have created a custom email service. should i send the email to the very long sf generated email address or can i send it to a smaller one like which in turn will forward to this email address.

    • JitendraZaa

      Email to anyone of them will work. At the end, it is important that long email should get email.

      • Ram

        cool. Any idea how bounced email messages work and whether they are stored in the email message object? I need to update certain fields when a email bounces(when being sent from Salesforce)

        • JitendraZaa

          Hi Ram, We dont have that information exposed in API yet…

  • Pavan

    My assignment rule is not firing on case created through Email services. Can you please guide what could be the issue

    • JitendraZaa

      Hi pavan, check assignment rule criteria and support settings under case.

  • Arvind Yadav

    if we have two support email Ids where we are getting emails from our customers . how can we identify on which support email they have send there case .??

    thanks in advance !

    • JitendraZaa

      In that case, create two email services and write custom logic in each email service. You can do anything to identify as they are having different classes.

      • Arvind Yadav

        thanks for the reply .

    Hi Jitendra,

    I have following requirment,

    For email2cases, currently salesforce creates cases without consider if constomer wants p1 or p2 severity logged, it simply takes email and logs cases.
    can we have customers use template and salesforce considers whats in template and logs case so that case fields are populated as per what customer seleected like P1 for severity.

    I believe email service as you mentioned is our only option?
    If so, how do i parse email body for lets say if we have 4 fields like this in email body which customer has sent to us assuming anuthing in the brackets is field name[ ]




    • JitendraZaa

      Hello Jay, We cant use Email-to-Case to decide severity.

      For Email Services, in your case, You will need to write Parser logic to fetch your field values and decide on severity.

    Hi jitendra,
    I am getting the following error while implementing the above code.

    (Undelivered): 554 The apex class CreateContactFrmEmail failed due to: System.NullPointerException: Attempt to de-reference a null object

  • Dinesh Singla

    Hi Jitendra,

    You are using a insert operation in for it okay to use insert in for loop in email services

    • That’s very good question 🙂 . I didn’t found any documentation saying Email services execute in Bulk. Whenever email is sent to email address, this class will be executed and for every email this class will have its own transaction. So, I guess its ok to write DML in loop. If you see this example then here also, DML is written in loop –

      • Dinesh Singla

        I already saw that but did not found any any thing.
        that’s why i posted here 😉
        Thanks for your clarification.

    Hi how to disable the auto replay ?


    I am exactly replicating the steps, however its not working for me. No new contact is generated after doing so..can you guess the issue?

    • Is your email service apex class is being invoked at all, did you checked debug logs ?
