Build a professional HTML email signature in seconds. Fill in your details, upload a logo, pick your brand colour, and copy the HTML.
The output uses table-based HTML — the broadest-compatibility format. Gmail, Outlook, Apple Mail, Yahoo, Thunderbird and most mobile clients render it correctly.
The logo is embedded as a base64 data URL directly inside the HTML, so clients that block external images still display it.
Gmail → Settings → See all settings → Signature → Create new → paste. Gmail renders the HTML on save.
