What are Email Services in Salesforce and How to create  Email Services?

Email services:

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

For example, you can create an email service that automatically creates contact records based on contact information in messages. Each email service has one or more email service addresses that can receive messages for processing.

To use the email services, click Your Name ➤ Setup ➤ Develop ➤ Email Services.

Given below email service class inserts Contact which is declare in setting of Email Services.

Class for Email Services:

global class ProcessJobApplicantEmail implements Messaging.InboundEmailHandler {

  global Messaging.InboundEmailResult handleInboundEmail(Messaging.InboundEmail email,

    Messaging.InboundEnvelope envelope) {

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

    Contact contact = new Contact();

    contact.FirstName = email.fromname.substring(0,email.fromname.indexOf(' '));

    contact.LastName = email.fromname.substring(email.fromname.indexOf(' '));

    contact.Email = envelope.fromAddress;

    insert contact;

    System.debug('====> Created contact '+contact.Id);

    if (email.binaryAttachments != null && email.binaryAttachments.size() > 0) {

      for (integer i = 0 ; i < email.binaryAttachments.size() ; i++) {

        Attachment attachment = new Attachment();

        // attach to the newly created contact record

        attachment.ParentId = contact.Id;

        attachment.Name = email.binaryAttachments[i].filename;

        attachment.Body = email.binaryAttachments[i].body;

        insert attachment;

      }

    }

     return result;

  }

}

Test Class for Email Service:

@isTest

private class EmailTest{

static testMethod void testMe() {

  // create a new email and envelope object

  Messaging.InboundEmail email = new Messaging.InboundEmail() ;

  Messaging.InboundEnvelope env = new Messaging.InboundEnvelope();

  // setup the data for the email

  email.subject = 'Test Job Applicant';

  email.fromname = 'FirstName1 LastName1';

  env.fromAddress = 'raees.sabir@accenture.com';

  // add an attachment

  Messaging.InboundEmail.BinaryAttachment attachment = new Messaging.InboundEmail.BinaryAttachment();

  attachment.body = blob.valueOf('my attachment text');

  attachment.fileName = 'textfile.txt';

  attachment.mimeTypeSubType = 'text/plain';

  email.binaryAttachments =

    new Messaging.inboundEmail.BinaryAttachment[] { attachment };

  // call the email service class and test it with the data in the testMethod

  ProcessJobApplicantEmail emailProcess = new ProcessJobApplicantEmail();

  emailProcess.handleInboundEmail(email, env);

  // query for the contact the email service created

  Contact contact = [select id, firstName, lastName, email from contact

    where firstName = 'FirstName1' and lastName = 'LastName1'];

  System.assertEquals(contact.firstName,'FirstName1');

  System.assertEquals(contact.lastName,'LastName1');

  System.assertEquals(contact.email,'raees.sabir@accenture.com');

  // find the attachment

  Attachment a = [select name from attachment where parentId = :contact.id];

  System.assertEquals(a.name,'textfile.txt');

 }

}
