Today, we will illustrate how you can send up to 1000 emails to contacts using a Visualforce email template.
1. Create Visualforce email template in your Salesforce.com instance:
Go to Setup < Communication Templates < Email Templates and click "New Template"
2. Select Visualforce.
4. Edit your template.
5. Now, you have different options to leverage this email template.
- Create a custom Visualforce page, and a custom controller that you will use as a list button in the Contact tab.
- Write a script and run it through Execute Anonymous in Eclipse or the Developer Console.
Today, we will be using the latter option:
We will create a list with contacts that we will send the emails to (max. 1000). Then we will create a batch of emails. After that we will send the emails to the recipients.
// List that will store emails that will be sent List allMails = new List();
// list of contacts List contacts = [Select id, Email, LastName from Contact Limit:1000];
// Email Template EmailTemplate myEMailTemplate = [Select id from EmailTemplate where Name =: 'Test Template'];
// emails are being created and stored in list for(Contact c: contacts){ Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage(); e email.setTargetObjectId(c.id); email.setSenderDisplayName('Sender Display Name'); allMails.add(email);
}
// send emails, false makes sure that the method will not stop when an error occurred, such as a bounced email
Messaging.sendEmail(allMails, false);
