Dynamic template fields can introduce XSS-like risks if HTML is not sanitized properly.
XSS Risk in Email Templates matters when you insert dynamic fields into HTML emails. If user-generated content or untrusted input is injected without sanitization, it can break layouts or create security issues in downstream systems that render or preview HTML. While email clients limit scripts, the risk can still appear in admin dashboards, preview tools, and internal web views. A strong platform sanitizes HTML, escapes merge fields by default, and offers safe formatting options. This topic is valuable for security-focused users evaluating automation tooling.
