Email Signature Generator
Free email signature generator — build a clean, table-based HTML signature with your logo, title, phone, email and website, preview it live, then paste it into Gmail, Outlook or Apple Mail. Runs entirely in your browser.
The logo is not shown here — this site refuses to load third-party images. It will appear normally once the signature is in your email client.
Runs entirely in your browser — nothing you enter is uploaded or stored.
About email signatures
An email signature is one of the few pieces of HTML you cannot test in a browser and trust. Outlook on Windows renders mail through Word's layout engine, Gmail strips<style> blocks and rewrites class names, and mobile clients apply their own scaling. Anything built with flexbox, grid or an external stylesheet will fall apart somewhere.
This generator emits what actually survives: nested tables, inline styles, absolute font stacks and a fixed-width logo. Copy the rendered signature into Gmail or Outlook and the formatting comes with it; copy the HTML if you are pasting into a client that takes raw markup, or into a template your organisation manages centrally.
Host the logo somewhere public — an email client fetches it over the network when the message is opened, so a local file or a data URI will not survive the trip. Keep it around 64 px tall and serve it over HTTPS.
Frequently asked questions
How do I add this signature to Gmail?
Click "Copy signature" (not the HTML), then go to Gmail → Settings → See all settings → General → Signature, and paste into the editor. Copying the rendered signature rather than the markup keeps the formatting; pasting raw HTML into Gmail would show the tags as text.
How do I add it to Outlook or Apple Mail?
Outlook on the web takes the same "Copy signature" paste into Settings → Mail → Compose and reply. Desktop Outlook and Apple Mail both accept a pasted signature too; for Apple Mail, create a signature first, then paste over the placeholder text.
Why does my logo not show in the preview?
This site blocks third-party images in its Content-Security-Policy — that is the same policy that guarantees nothing you type can be uploaded. The preview shows a placeholder instead, but the real image URL is in the copied HTML and will load normally in an email client.
Why are tables used instead of modern CSS?
Email clients are not browsers. Outlook renders with Word’s engine and Gmail strips <style> blocks, so flexbox and grid break in ways you cannot test for. Nested tables with inline styles are the only layout that renders consistently everywhere, which is why every serious signature uses them.
Is anything uploaded?
No. The signature is built in your browser as you type — there is no request, and the Content-Security-Policy on this site has no endpoint that could receive one.
