Email Signature HTML Builder

Generate a clean, copy-paste HTML email signature that renders correctly in Gmail, Outlook, and Apple Mail — with avatar/logo, social icons (auto-detected from your links), accent color, light/dark/auto theme, and a table-based email-safe layout using inline styles. Copy the raw HTML and paste straight into your mail client.
