Design one template. Eigenlaut fills it from your Google Workspace directory and keeps every mailbox in step, automatically.
30 days free, no card required.
Rendered live by Eigenlaut’s template engine, the code that writes your signatures to Gmail.
People copy an old signature, keep a former job title or add a quote of their own. Eigenlaut writes one design for everyone, filled from the directory you already keep up to date.

With Eigenlaut
A super admin authorises Eigenlaut’s service account for three scopes in the Admin console, then signs in with Google and verifies the connection. No app to install, no consent screen for your people.
API controlsManage Domain Wide Delegation
Start from four templates or paste your own HTML. Placeholders fill from the directory, and rules pick the template for each team.
{FullName}
{#if JobTitle}{JobTitle}{/if}
{CompanyName}A dry run shows every change per user. Then apply, and switch on the daily sync for new starters, new titles and hand edits.
Start from four starters or paste your own HTML. Fields like {JobTitle} and {PhoneNumber} fill from Google’s directory, and {#if} blocks leave out empty lines.
<b style="color:{PrimaryColor}">{FullName}</b><br>
{#if JobTitle}{JobTitle}, {/if}{CompanyName}<br>
{#if MobileNumber}M {MobileNumber}{/if}Rendered for two people, one without a mobile number
Choose the template by organisational unit, group, department or address. The first matching rule wins, and a rule can leave people out.
Add a banner for a launch or an event, with a start and an end date, for everyone or one team. It goes in and out with the next run.

Shown from 1 November to 30 November
See for every user which signatures would change, then apply. Results of each run stay for 90 days.
When someone edits their signature in Gmail, the next run puts the company version back and records it. With the daily sync, new starters and new titles follow within a day.

Admins, editors and viewers. Every change, sign-in and run is logged, and admins export the log as CSV.
The same code on your own Cloudflare account, with your own service account. No billing, and the data can stay in the EU jurisdiction.
npx wrangler deployYour super admin authorises Eigenlaut for exactly three Google scopes through domain-wide delegation, and can revoke them at any time in the Admin console.
Directory users, read only
admin.directory.user.readonly
Lists your users and reads the fields signatures use: name, job title, department, phone numbers, work location, custom fields and whether someone is an admin.
Gmail basic settings
gmail.settings.basic
Reads each user’s send-as addresses and changes one field: the signature. It never touches filters, forwarding or any other setting.
Group members, read only
admin.directory.group.member.readonly
Reads the members of the groups you use in rules or campaign targets, and only those.
Addresses with run results, hashes of signatures, and organisational unit paths and departments for the rule editor. No names, job titles or phone numbers, and no IP addresses.
Pay only for mailboxes whose signature Eigenlaut manages, after a 30-day trial without a card.

Only what three scopes allow: reading directory users, reading group members, and reading and updating Gmail signature settings. Your super admin grants them in the Admin console through domain-wide delegation, and Eigenlaut uses them only for the addresses your own directory lists.
No. None of the three scopes gives access to messages, attachments, Drive or Calendar. Eigenlaut reads the send-as addresses of each user and writes one setting: the signature.
The next run puts the company signature back and records it in the run results. With the daily schedule switched on, that happens within a day.
The hosted edition runs on Cloudflare (Workers, a D1 database and Queues); the database and the queue are in Cloudflare’s EU jurisdiction, and billing runs through Stripe. The database keeps addresses with run results, hashes of signatures, the organisational unit paths and departments for the rule editor and the organisation’s e-mail domains for sign-in, but no names, job titles or phone numbers. Self-hosted, everything stays in your own Cloudflare account, in the EU jurisdiction if you choose it.
Yes, for free. The self-hosted edition is the same code on your own Cloudflare account, with your own Google service account and no billing. The documentation has the guide.
Yes. You cancel the subscription in the billing portal, which you open from the dashboard. Live updates to Gmail stop when the subscription ends, and the organisation is deleted with all of its data 30 days later unless you subscribe again. You can delete it yourself at any time, which cancels the subscription too. To cut access at once, delete Eigenlaut’s client ID in the Admin console under Security › Access and data control › API controls › Manage Domain Wide Delegation.
