Today, Xiaobian will share with you the relevant knowledge points on how Salesforce realizes the email function. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you will gain something after reading this article. Let's find out together.

First of all, let's get this straight.

To send an email, we need to have the following parts,

1. title

2. content

3. recipient

4. CC

Understanding salesforce is easy by design knowing the title and content, but the hard part is finding some recipients. Anyway, let's get this straight.

We're going to send emails to members of the community group, so let's start with

The first step is to find the common group object, and the second step is that a group must have its group members, and the members of the group are actually what we often call users.

To put it bluntly, sending an email to a utility group is actually sending an email to the members of the group.

Here we can know the relationship between the three objects.

The group member object acts as an intermediate table connecting the common group and user objects.

//public static boolean sendMail() { Boolean result = true; String title = ''; String body = ''; List toMailList = new List(); //List ccMailList = new List(); List statementIdList = new List(); Date today = Date.today(); //Title and Content title = 'Email public groups'; body += 'Hello, my friends! '; body += 'Welcome to Miao Xiaomiao's blog! '; body += 'thank you'; body += '(^_^)~ Meow ~!! '; //addressee and cc //1. mail group //String str = System.Label.OPDTPMailboxGroup; toMailList.addAll(str.split(';')); //2. public group //used to store user id List idList = new List(); //query public group List gList = [ SELECT (select userOrGroupId from groupMembers) FROM group WHERE name = 'MyGroupName']; if (gList != null && gList.size() > 0) { for (Group g : gList) { for (GroupMember gm : g.groupMembers) { idList.add(gm.userOrGroupId); } } } //Query user information according to user id List usrList = [SELECT email FROM user WHERE id in :idList]; //Get the email of each user for (User u : usrList) { toMailList.add(u.email); } List sendMails = new List(); Messaging.SingleEmailMessage messageNEW = new Messaging.SingleEmailMessage(); messageNEW.setSubject(title); messageNEW.setHtmlBody(body); messageNEW.setCharset('UTF-8'); messageNEW.setToAddresses(toMailList); //messageNEW.setCcAddresses(ccMailList); sendMails.add(messageNEW); if (sendMails.size() > 0) { Messaging.SendEmailResult[] results = messaging.sendEmail(sendMails); for (Integer i = 0; i < results.size(); i++) { if (results[i].success == false) { system.debug('=====send mail error:' + results[i].errors[0].message); result = false; } } } return result; } That's all for Salesforce How to Send Email.
