Feature Tags

Many of ePriority's content-oriented features are implemented with feature tags. These tags are processed in all content files for which parsing has been turned on, and in the subject lines of messages as they are generated.

ePriority feature tags are similar in form to those used in SGML, HTML, and XML. The general form of a tag is:

        {{feature name:value}}

All ePriority tags, except personalized data tags, require a name property to identify the feature. Some features require or allow additional properties. Neither the feature name nor the property names are case-sensitive but the values are.

Features supported or activated by tags include:

• Form Letter Generation (PData)
• Opt Out Tracking (OptOut)
• Link Tracking (ClickTrack)
• View Tracking (OpenTrack)
• Control Blocks (if and foreach)
• MIME Content ID Lookup (ContentID)

Content ID Lookup (ContentID)

Content ID tags are used to get the MIME content IDs of files in a multipart message. When one part of a structured mail message refers to another part, it uses the MIME content ID. Since the content ID cannot be known until ePriority actually builds the mail message, you need to use this tag to refer to other items in the message.

        {{ContentID:filename}}

The file attribute identifies by name the file whose content ID you want to replace the tag with.

The most common use of content ID tags is embedding images in HTML documents.

For a more detailed description of this tag, see the ePriority Service Overview.
