Why this uses tables
Outlook on Windows renders email with Microsoft Word's layout engine, not a browser engine. It
ignores flexbox, grid, most positioning and many modern CSS properties. A signature built with
divs and flexbox looks perfect in Gmail and collapses into a stack of unstyled text in
Outlook — which is where a large share of business email is still read.
Table-based markup with inline styles is ugly to write and the only thing that renders everywhere.
Adding it to your mail client
- Gmail: Settings → See all settings → Signature → paste.
- Outlook (web): Settings → Mail → Compose and reply → paste.
- Apple Mail: Settings → Signatures → paste, then untick "Always match my default message font".
Paste the rendered preview, not the HTML source — mail clients expect formatted content, not code.
Common questions
Why does my signature break in Outlook?
Outlook on Windows renders mail with Microsoft Word's engine, which ignores most modern CSS — flexbox, grid and many float layouts. This generator outputs table-based HTML with inline styles, which is the only thing that renders reliably everywhere.
Is my information sent anywhere?
No. The signature is built in your browser and never reaches our server.
