Free email signature generator

Add the signature in Gmail

1. Copy the signature — with the “Copy signature” button above.
2. Open settings — in Gmail: gear icon → See all settings → General tab.
3. Paste — into the Signature box, create a new one if needed, then save at the bottom of the page.

Add the signature in Outlook

1. Copy the signature — with the “Copy signature” button.
2. Open signature settings — Outlook on the web and new Outlook: Settings → Accounts → Signatures. Classic Outlook: File → Options → Mail → Signatures.
3. Paste and choose — the default signature for new messages and for replies.

Add the signature in Apple Mail

In Mail → Settings → Signatures, create a signature, untick “Always match my default message font”, then paste. Formatting is kept.

Why a table-based signature?

Email clients do not render HTML like a browser. Outlook for Windows uses Word’s rendering engine, which ignores much of modern CSS. A signature built with tables, inline styles and system fonts displays the same everywhere.

That is what this generator produces. To go further, read our guide to HTML signature compatibility.

One signature, or the whole company’s?

A generator is fine for one person. At twenty, fifty or two hundred, copy-paste produces mismatched signatures, and every logo change means everyone starts over.

Soniako reads your Google Workspace or Microsoft 365 directory, builds each person’s signature and deploys it: straight into Gmail, or through an Outlook add-in deployed once. Free for up to 5 people.
