Sending an email from Apex Class is so easy.
The Apex Messaging.SingleEmailMessage class handles the email functionality available to Salesforce.
Basically there are two categories:
- SingleEmailMessage – This class is used when a use case requirement to send to email to a single person. This contains methods for sending single email messages.
- MassEmailMessage – This class is used when a use case requirement to send an email to a group.
Explanation about SingleEmailMessage :-
The following are methods for SingleEmailMessage.
- setBccAddresses(bccAddresses) : This is Optional. This contains list of blind carbon copy (BCC) addresses. If the BCC compliance option is set in your org at the organization level, then the user cannot add any BCC addresses on standard messages. You will get the below error code: BCC_NOT_ALLOWED_IF_BCC_ COMPLIANCE_ENABLED. You can contact to your Salesforce representative for information on BCC compliance.
- setCcAddresses(ccAddresses): This is Optional. This contains list of carbon copy (CC) addresses
- setCharset(characterSet) : This is Optional . The character set for the email. If character set value is null, then the user’s default value is used.

Amazon translation API :-
An affordable service for more natural, precise translations. It rests on state-of-the-art deep learning models, as opposed to traditional statistical and rule-based algorithms.
In our implementation, a VisualForce Page comes up with a Lightning Component to accept a source and target language, subject, recipient email, and body. Only the message body gets translated. It goes without saying, that the functionality builds on the standard ‘Messaging.SingleEmailessage’ to send out emails to individuals. Here’s a look at our source code for you to dive in:
Here is the Amazon API authentication code:-
Here we are explaining SingleEmailMessage category. Below is the code snippet which sends an email to single user from apex. I have created one Lightning component and controller related to it. Lightning component have Send Email button.
Once user clicks on the button, we are sending email using apex code.
Try this for sending emails to a single user.
Step 1 :
Step 2: Create a lightning component and paste the code below.

OR
You can Go to the URL and type (Change the yoursalesforceinstance with your salesforce org URL)
