Apex beginner - Email from a trigger

Question

I was trying with a code for sending mails using Apex. The code is working but it is not able receive any mails? Can anyone help me with this?

Answer 1

So, basically you are not using the function called Messaging.sendEmail to send an email. Try the below code:

trigger Test1 on Contact (after update) {

        Messaging.reserveSingleEmailCapacity(trigger.size);

        List<Messaging.SingleEmailMessage> emails = new List<Messaging.SingleEmailMessage>();

        for (Contact c : trigger.new) { // walk through all records which is processed

            Contact old = trigger.oldMap.get(c.Id); // get old record from oldMap

            if (old.Email != c.Email ) { // check current email 

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

                email.setToAddresses(new String[] {c.Email};);

                email.setReplyTo('[email protected]');

                email.setSenderDisplayName('Mr Apex Tester');

                email.setSubject('Subjected to Learning');

                email.setPlainTextBody('You have just changed your SalesForce contact email from ' + 

                    old.Email + ' to ' + c.Email +

                     '. If this was not intentional please log back into Salesforce.com and ammend you details.');

                emails.add(email);

            }

        }

        Messaging.sendEmail(emails);

    }

I hope this will help.
