Sending emails from Apex isn’t complicated, but most developers are overwhelmed with the process.<\/p>\n\n\n\n

However, APEX provides classes for composing email messages. Let us walk you through a practical, clean implementation of how to send an email from APEX.<\/p>\n\n\n\n

Understanding How Apex Handles Email<\/h2>\n\n\n\n

Salesforce sends emails through the Messaging class. The workhorse here is Messaging.SingleEmailMessage<\/strong>. This class can help you send a single email message to one or more people.<\/p>\n\n\n\n

The setToAddresses()<\/strong> funtion set the To<\/strong> field of the email. You can provide one email address or multiple addresses as input, separating them with a semicolon.<\/p>\n\n\n\n

Next, the setCcAddresses()<\/strong> function sets the CC<\/strong> field of the email. On the other hand, the setInReplyTo()<\/strong> function differs in that it takes a string as an argument.<\/p>\n\n\n\n

Furthermore, the setSubject()<\/strong> function sets the e-mail subject, and thesetHtmlBody()<\/strong> sets the e-mail body in HTML form. <\/p>\n\n\n\n

But if you want to set the body in text format, then use the function setPlainTextBody()<\/strong>. Once configured, use the sendEmail()<\/strong> function and Salesforce handles delivery.<\/p>\n\n\n\n

Basic Apex Code to Send an Email<\/h2>\n<\/div><\/div>\n\n\n\n

This sends a plain-text email to a direct address.<\/p>\n\n\n\n

public class emailSending {\n    public string toMail { get; set;}\n    public string ccMail { get; set;}\n    public string repMail { get; set;}\n    \n    public void sendMail(){\n        Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();\n        string[] to = new string[] {toMail};\n        string[] cc = new string[] {ccMail};\n        \n        email.setToAddresses(to);\n        if(ccMail!=null && ccMail != '')\n            email.setCcAddresses(cc);\n        if(repmail!=null && repmail!= '')\n            email.setInReplyTo(repMail);\n        \n        email.setSubject('Test Mail');\n        \n        email.setHtmlBody('Hello, <br\/><br\/>This is the test mail that you generated. <br\/>The Email Id for which this mail was generated by '+toMail+'<br\/><br\/>Regards<br\/> Developer');\n        try{\n            Messaging.sendEmail(new Messaging.SingleEmailMessage[] { email });\n        }catch(exception e){\n            apexpages.addmessage(new apexpages.message(apexpages.severity.error,e.getMessage()));\n        }\n        \n        toMail = '';\n        ccMail = '';\n        repMail = '';\n    }\n}<\/pre>\n\n\n\n

The Code for my VF page is something like this:<\/p>\n\n\n\n
<apex:page controller="emailSending">\n    <p>\n        Test Email Sending:\n    <\/p>\n    <apex:form>\n        <apex:outputLabel value="Send Mail To: " for="To"\/>\n        <apex:inputText value="{!toMail}" id="To"\/><br\/>\n        <apex:outputLabel value="CC Mail To: " for="CC"\/>\n        <apex:inputText value="{!ccMail}" id="CC"\/><br\/>\n        <apex:outputLabel value="Reply Mail To: " for="rep"\/>\n        <apex:inputText value="{!repMail}" id="rep"\/><br\/>\n        <apex:commandButton action="{!sendMail}" value="Send Email"\/>\n    <\/apex:form>\n<\/apex:page><\/pre>\n\n\n\n

A Practical Note on Apex Email Limits<\/strong><\/h2>\n\n\n\n
This is the part most tutorials skip.<\/p>\n\n\n\n
Salesforce enforces daily email limits when you hit them; your code still runs, but messages don\u2019t leave the org.<\/p>\n\n\n\n
Apex email is powerful, but it\u2019s not an unlimited infrastructure. If you\u2019re building automated notifications at scale, design with limits in mind:<\/p>\n\n\n\n
