Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

AttachmentRetrievalOption Enum

Provides options for including attachment metadata only, attachment metadata and content, or excluding attachments.

Namespace

Messaging

Usage

Sending an email by using Apex requires domain-level and user-level email verification. System-generated emails also require verification of the From email address. Email delivery fails if any of these verifications is incomplete. See Requirements to Send Email from Salesforce.

Important

Use these enum values with the renderStoredEmailTemplate(templateId, whoId, whatId, attachmentRetrievalOption) method.

Enum Values

The following are the values of the Messaging.AttachmentRetrievalOption enum.

Value Description
METADATA_ONLY Includes only the file name, content type, and the object ID in the fileAttachments property of Messaging.SingleEmailMessage. When the template is rendered from a Visualforce template (and not from a static file attached to the template), the object ID is not available.
METADATA_WITH_BODY Includes the attachment content, in addition to the file name, content type, and the object ID in the fileAttachments property of Messaging.SingleEmailMessage.
NONE Doesn’t include any attachments in Messaging.SingleEmailMessage.
