Hey — thanks for sending this over. The team took a look this morning and we're aligned on everything. A couple of small notes inline, otherwise ship it.

What you see here is the exact HTML you copy — nothing is re-rendered from the form. If it looks right here, it will look right in Gmail, Outlook and Apple Mail.

Table-based markup with inline styles — compatible with Gmail, Outlook desktop, Apple Mail and every major client. No external fonts, no external requests, no tracking pixels.

Install in your mail client
Gmail
Settings → See all settings → Signatures → Create new → paste the HTML (Cmd/Ctrl+V) → Save. In the compose window, click the pen icon and pick your signature.
Outlook
New message → Insert → Signature → Signatures… → New → paste the HTML → OK → set it as default.
Apple Mail
Mail → Settings → Signatures → select your account → click the signature row → paste the HTML (Edit → Paste — not Paste and Match Style).

How it works

From blank page to signature in about a minute.

01

Design it

Pick a template, drop in your name, role and contacts, set your accent colour. Changes render live in the inbox preview.

02

Copy the code

One click copies clean, table-based HTML with inline styles — the format every mail client actually renders faithfully.

03

Paste it once

Gmail, Outlook or Apple Mail — paste into your signature settings and it works on every device you send from.

FAQ

Questions, answered.

Will my signature actually work in Outlook?

Yes. Signatures are generated as table-based HTML with inline styles — the exact approach Outlook desktop requires. No divs, no external stylesheets, nothing that gets stripped.

Is it really free? No hidden watermark?

Really free. Three templates cost nothing, there is no watermark and no 'Made with SigForge' footer. Five premium templates cost a one-time $9 via secure checkout — you get a license key by email, and the free ones are complete, not crippled.

Do I need to create an account?

No. Everything is stored in your browser's local storage. Your data never touches our server, which also means your avatar and details are never uploaded anywhere.

Can I use my company logo?

Yes — upload a logo or photo as the avatar. It is resized locally to 144px before being embedded, so your signature stays light and loads instantly in every email.

Will the icons and links work on every device?

Social and contact links are plain <a> tags with inline SVG icons embedded as data URIs, so they render identically on desktop, mobile, Gmail apps and webmail.
