How to Send email from Apex class.

This is most common question most of the developer ask, How to send emails from apex class? , so here in this blog we are going to see that.

Step 1. Go to your name -> Developer Console ->File -> New -> Apex Class

Step 2: Create one method and copy all the mentioned code into your method.

list<Messaging.SingleEmailMessage> mlist =new List<Messaging.SingleEmailMessage>(); 

Define List of To Address

String [] Addresses=new String[0]; 

Define List of To Address

String [] CCAddresses=new String[0];
Messaging.SingleEmailMessage email=new Messaging.SingleEmailMessage();
addresses.add('Cloudwale@gmail.com');
CCAddresses.add('Cloudwale@gmail.com');
email.SetToaddresses(addresses);
email.setCcAddresses(CCAddresses);

If you wanted send email without classic email templates you can use following code to set subject and body.

email.setSubject('Quote From Cloudwaale');
email.setPlainTextBody('Please find attached quotation');

Target Object can only be user, Lead and Contact.

email.setTargetObjectId(Userinfo.getUserId());

In case of User we have to use following method

 email.setSaveAsActivity(false);
 email.setWhatId(qid);

Replace template id from your org

email.setTemplateId('00X********M7');

If you have any organization wide addresses you can sen that as from email

for(OrgWideEmailAddress owd:[select id,address,displayname from OrgWideEmailAddress])
{
email.setOrgWideEmailAddressId(owd.address);
}

If you not set any from email id system will take login users id as default from email .

To send attachment

List<Messaging.EmailFileAttachment> efaList=new List<Messaging.EmailFileAttachment>();
Messaging.EmailFileAttachment efa=new Messaging.EmailFileAttachment();

pdfBody you have to fetch it from attachment object

 efa.body=pdfBody; //Blob
 efa.filename='QuotationPDF.pdf';
 efaList.add(efa);
 email.setFileAttachments(efaList);
 mlist.add(email);

This will send email and store result in result list.

Messaging.SendEmailResult [] result=Messaging.sendEmail(mlist);
