XML(Extensible Markup Language)

A markup language used for structuring data, including DMARC reports and email-related data formats.

Definition

XML (Extensible Markup Language) is a markup language designed for storing and transporting data in a structured, human-readable format. In email marketing, XML is commonly encountered in DMARC aggregate reports, RSS feeds for email content, and data import/export formats. Understanding XML helps you work with email authentication reports and data integration.

Why It Matters

DMARC aggregate reports are delivered in XML format, so understanding XML helps you interpret these critical deliverability reports. Many data integration tasks involve XML. Some email platforms use XML for template definitions or configuration.

How It Works

XML uses tags to define data elements and their relationships. A DMARC report, for example, contains XML tags for report metadata, policies, and individual authentication records. XML parsers and reporting tools convert this structured data into readable formats.

Best Practices

  • 1Use DMARC reporting services to parse XML reports automatically
  • 2When working with XML exports, validate the format before importing
  • 3Keep XML files well-formatted and properly escaped
  • 4Use tools rather than manual parsing for complex XML data

Frequently Asked Questions

DMARC XML reports can be complex. Use a DMARC reporting service or online parser to convert them into readable dashboards. These tools aggregate data from multiple reports and highlight issues.

DMARC reports use XML. Some ESPs support XML for data import/export. RSS feeds (XML-based) can be used for dynamic email content. API responses may also be XML-formatted.
