One email signature. Every employee. No IT rollout.
Design your company signature once and add your team. Everyone gets a personal link with their finished signature to paste into Gmail, Outlook, or Apple Mail — SignatoryGrid never needs access to your inboxes.
- No inbox access
- No plugins
- No employee accounts
- No IT rollout
Right now, every employee's signature is a little different — and nobody knows which one is actually approved.
- Someone is still using the old logo
- Someone has the wrong phone number
- Sales reformatted theirs
- New hires have no signature at all
What your team sends
Rendered live by the same engine your signatures use.

||||||||||||
Brand editor
Logo, brand color, layout, tagline, social links, and an optional call-to-action — edited in one panel with a live preview.
Employee roster
Add teammates one at a time or import a spreadsheet. Edit anyone later; their signature updates with them.
Renders correctly where it matters
Output is table-based HTML with inline styles and pixel image sizes — the format the Word rendering engine in classic Outlook needs, and the one Gmail keeps intact when you paste.
Personal claim links
Each teammate gets a URL, copies their signature with one click, and pastes it in. No accounts for them to create.

How it works
You design → we generate → they paste.
One approved template, one roster, one link per person. No mail-server access, no plugins, and nothing for your employees to sign up for.
- 01
Design the company signature
Pick your logo, brand color, layout, and tagline in a live editor. That version becomes the approved one.
- 02
Add your employees
Names, roles, phone numbers, links, and photos — one at a time or imported from a spreadsheet.
- 03
Share personal claim links
Each teammate gets their own URL with their finished signature and install instructions. No accounts, no MDM.
- 04
They copy and paste
One click copies the HTML. It goes into Gmail, Outlook, or Apple Mail signature settings in seconds.
Security & privacy
Email signature management without email administration.
SignatoryGrid sits outside your mail system on purpose. It generates signatures and hands them to your team as a link — so there is nothing to connect, install, or deploy, and far less of your email surface is involved.
- No connection to Gmail inboxes
- No connection to Microsoft 365 mailboxes
- No mail-server or admin credentials
- No browser extensions or plugins
- No SignatoryGrid accounts for employees
- No IT deployment or MDM policy
No inbox access required
We never connect to Gmail, Microsoft 365, or your mail server. Employees paste their own signature.
Used only to generate signatures
The names, titles, and contact details you provide are used solely to render each employee's signature.
Encrypted in transit
Every request between your browser, the app, and our storage runs over TLS.
Delete anytime
Remove an employee, or delete your account entirely, and their data comes with it.

Pricing
Free, with no usage limits.
SignatoryGrid is free to use today: unlimited employees, every template, and every tool. There is no card to enter and nothing to cancel. If paid plans are ever introduced, they will cover future features — not the ones you are already using.
Why it's free
Small businesses deserve to look credible on day one.
When you are just starting out, the first thing anyone judges is the email you send. A clean, consistent signature with your name, role, logo, and links is a small detail that makes a new company read as established and verified — and it should not cost a monthly subscription to get.
So SignatoryGrid is free: unlimited signatures, unlimited teammates, every template. No card, no trial timer, no upsell in the middle of setting up your team.
Who built this
SignatoryGrid is built by George Greer, a high school student interested in AI and software. It started as a weekend project to help local businesses look professional, and it stays free because that was the whole point.

Answers before you sign up.
Does SignatoryGrid access employee inboxes?
No. SignatoryGrid never connects to your mail server and never reads or sends email. Each employee copies their signature from a personal claim link and pastes it into their own mail client.
Can a slot be reassigned to a new employee?
Yes. Admin accounts can rewrite or delete any slot when someone leaves — the slot itself is permanent, so a new hire can take it over.
What happens when employee information changes?
Update the employee in your dashboard and their personal claim link immediately reflects the latest signature. A signature already pasted into a mail client does not change on its own — the teammate reopens their link and re-pastes the updated version, which takes a few seconds.
Why is SignatoryGrid free, and what can I expect?
SignatoryGrid is built by a solo high-school developer to help small teams look credible from day one, so it is free with unlimited employees, every template, and every tool — no card and nothing to cancel. It is offered as-is, without a support contract or uptime guarantee. If paid plans ever arrive, they will cover future features rather than what you already use.
Where are logos hosted?
Logos you upload are stored on SignatoryGrid's own storage and served over HTTPS. Every generated signature references that hosted URL so images render reliably in Gmail, Outlook, and Apple Mail.
Which versions of Outlook are supported?
SignatoryGrid emits table-based HTML with inlined styles, which is what Outlook 2016, 2019, 2021, Microsoft 365, the new Outlook for Windows, and Outlook on the web all expect.
Can one account manage multiple brands?
One account manages one brand today. If you run multiple brands, create a separate SignatoryGrid workspace per brand — this keeps logos, colors, and claim links cleanly scoped.
Are social icons and promotional banners supported?
Yes. The brand editor supports LinkedIn, Twitter/X, Instagram, Facebook, YouTube, and GitHub links, plus an optional promotional banner image with a click-through URL under each signature.
How is employee data deleted?
Delete an employee from the dashboard to remove their signature and personal claim link. You can also delete your entire account at any time to remove all employee data.
