📧 Signature Forge

Build an email signature that survives Gmail, Outlook and Apple Mail, then copy it with formatting intact and paste straight into your mail client. Table-based layout, inline styles only, no scripts, no tracking pixels — the three rules every paid signature tool pretends are hard.

How to install it, and why signatures break

Gmail: Settings → See all settings → Signature → paste. Outlook (web): Settings → Mail → Compose and reply. Apple Mail: Settings → Signatures → paste, then untick "Always match my default message font". Thunderbird: Account Settings → paste into Signature text and tick "Use HTML".

Signatures break for four reasons: CSS in a <style> block (Outlook strips it), flexbox (Outlook's Word-based renderer ignores it), webfonts (never load), and images over http:// (blocked). This generator therefore uses a single nested table with inline styles and system fonts only. Keep any logo under about 150px wide and always host it over https.

Privacy: everything is built in this tab. The one exception is deliberate — if you paste a logo URL, your browser fetches that image so the preview matches what recipients will see. Nothing you type is stored or sent anywhere else, and the URL is only ever requested by your own browser.
