A quick way to spot accessibility issues before you hit send. Copy an email from Gmail or Outlook, or paste the source code if you've got it, and your browser runs the scan locally. Nothing gets uploaded, nothing gets stored, and it's all gone the moment you close the tab.
It catches a lot, but the parts of email accessibility that matter most still need a human eye. Think of this as a fast first look and not a final verdict.

- Transparent PNG logos with dark linework — replace with SVG, or use a PNG with an explicit background that survives inversion.
- Hardcoded light backgrounds that don't adapt — declare
<meta name="color-scheme" content="light dark">in the email<head>so the client knows the email supports both. - Hardcoded text colours like
color:#000on light backgrounds — set both background and text, or useprefers-color-schememedia queries. - Text baked into images — switch to live HTML text so dark mode can re-colour it.
