AMP4Email Validator

A free tool: paste an AMP email and check it against the official AMP4Email specification, the same validator Gmail runs before it will render your dynamic email. Then let KINETIC repair the mechanical failures for you.

How to use it

1. Paste your AMP HTML into the editor (up to 1MB). A Sample button loads an example with two common AMP4Email errors, a cursor: grab value and a transition on a disallowed property.
2. Choose Validate to get the verdict, or Validate & auto-fix to validate and repair in one step.
3. Read the results: every error with its line, column and a link to the spec. Apply the fixed document back into the editor, re-validate, and copy it out.

What this checks

AMP4Email is a strict subset of AMP. Gmail validates every dynamic email before rendering it, and a single error means recipients see your HTML fallback instead. This page runs the official amphtml-validator in AMP4EMAIL mode, the same rules Gmail applies, and reports each failure with its line and column.

The auto-fix pass

Most AMP email failures are mechanical, for example:

• a transition on a property AMP does not animate
• a cursor value other than pointer
• a missing component import
• a relative href="#"
• hidden="false"

Auto-fix applies the same deterministic repairs the KINETIC generator runs on every AMP email it builds, then re-validates so you can see exactly what is left.
