Salesforce Governor Limits do not allow more than 10 calls to \``++Messaging.sendEmail++`` in a single transaction. There is a good chance that calling this method in a loop will reach that limit and fail. You can instead send a batch of emails with a single call to \``++Messaging.sendEmail++``.
|
||
|
||
|
||
This rule raises an issue when a call to ``++Messaging.sendEmail++`` is found in a loop.

trigger MyWelcomeTrigger on Contact (after insert) {

List<Id> toIds = new List<Id>();

if(contact.Email != null)
|

{
|

Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
|
||
String[] toAddresses = new String[] { contact.email };
|
||
mail.setToAddresses(toAddresses);
|

mail.setSubject('Welcome');
|
||
mail.setPlainTextBody('Welcome');
|
||
Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail }); // Noncompliant
