Visualforce Email Templates

Developers and administrators can use Visualforce to create email templates. The advantage of using Visualforce over standard HTML email templates is that Visualforce gives you the ability to perform advanced operations on data that is sent to a recipient.

Although Visualforce email templates use standard Visualforce components, they are not created in the same way. Visualforce email templates always use components that are prefaced with the messaging namespace. In addition, these topics provide more details.

All Visualforce email templates must be contained within a single <messaging:emailTemplate> tag. This is analogous to regular Visualforce pages being defined within a single <apex:page> tag.
The <messaging:emailTemplate> tag must contain either a single <messaging:htmlEmailBody> tag or a single <messaging:plainTextEmailBody> tag.
Several standard Visualforce components are not available for use within <messaging:emailTemplate>. These include <apex:detail>, <apex:pageBlock> and all related pageBlock components, and all input components such as <apex:form>. If you attempt to save a Visualforce email template with these components, an error message displays.
