On a VF page, I am making use of Custom Metadata Types and displaying some text to the end users which is going to the input for: setplainTextBody(subBody) to enable capability for editing it before sending out the email.

Using Messaging.SingleEmailMessage(); to send out the email to the contacts that are selected from below Wrapper class. I want to make this subBody to be one of the merge fields on an email template along with some standard fields: ContactName, Phone and other custom fields. Currently with this: mail.setplainTextBody(subBody); I can only send whatever data in that text area.

How can I implement this:

Dear {!Contact.FirstName},

{!Case.Email_Body__c} "This is subBody"

Case details:

Record Name: {!Kindle__c.Name}

Type of Record: {!Case.Kindle_Type__c}

Record title: {!Case.Subject} Kindle officer's Contact number: {!Case.KindleConNumb__c}

Extension(If any): {!Case.Extension__c}

Thank you, {!Kindle__c.OwnerFullName}

EDIT: This is my new implementation which ended up with an error:

I am getting an error: SendEmail failed. First exception on row 0; first error: EMAIL_TEMPLATE_MERGEFIELD_ERROR, Body: Field cw.con.Name does not exist. Check spelling.: [cw.con.Name]. This is my code:

  if(!atLeastOneSelected){
        for(cContact cw: contactList){
            if(cw.selected == TRUE){
                atLeastOneSelected = true;
                System.debug('Select Con:' +cw.con.Name);
                Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
                mail.setTreatBodiesAsTemplate(true);
                mail.setToAddresses(new String[] {cw.con.Email});
                mail.setplainTextBody('Dear {!cw.con.Name}' +subBody );
                mail.setSenderDisplayName('Kindler');
                mail.setSubject('Kindle's next Best');
                listEmail.add(mail);
                contactList = null;
            } 
        }  
    }

Using the System.debug I could see the selected contact's name, but ended up with this error.

You should look at the setTreatBodiesAsTemplate method.

Optional. If set to true, the subject, plain text, and HTML text bodies of the email are treated as template data.

Example usage:

Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();
email.setPlainTextBody('Sending a test to {!Contact.FirstName}');
email.setTreatBodiesAsTemplate(true);

// set other properties
// send email
  • As I already have my email template ready, can I make use of that template(by providing its ID) to send out the email to the selected contacts from the VF page? – Arnold Jr. Aug 29 '17 at 17:05
  • @ArnoldJr. You may have to query the template body, manipulate it, then pass it to your email message instance. – Adrian Larson Aug 29 '17 at 17:40
  • I was able to query the EmailTemplate and set: mail.setTemplateId(mailTemp.Id);, but how can I manipulate it's body now? – Arnold Jr. Aug 29 '17 at 17:57
  • Any suggestions? – Arnold Jr. Aug 31 '17 at 4:59
