"Append Footer solves a specific problem well: getting a standard disclaimer onto every outbound email from an organizational unit. It was never designed to manage personalized, role-based email signatures across a growing organization. When admins start creating OUs just to work around its limits, that's a sign they've already outgrown it."

What Google Workspace does natively
Google Workspace has two built-in ways to put an email signature on outbound mail. Neither requires extra software, and for straightforward, uniform needs, either can be enough.
Per-user Gmail signatures
Each person creates their own email signature in Gmail settings. It appears while composing and sends with their messages. This works for individual sign-offs, but each email signature is set and edited by the user. IT has no way to set or enforce it centrally. How to add a signature in Gmail
Append Footer
A setting in the Google Admin Console that applies a standard block of text to all outbound mail for users in a given organizational unit (OU), server-side and automatically. It works for a single, uniform footer: a legal disclaimer, a standard company sign-off, with no action required from users. How to create a Google Workspace email signature
No personalization from Google Directory
The Append Footer applies the same content to every user in an OU. It can't pull a name, job title, or phone number from Google Directory. When different teams, brands, or regions need different email signatures, each requires a separate OU with its own Append Footer to configure and maintain. The admin overhead grows with every new entity added.
Gmail signatures sit outside IT's reach
Users set their own email signature in Gmail settings regardless of what the Append Footer applies. When both are active, the Append Footer appends to the bottom of the thread on every reply while the user's Gmail signature appears in the compose window. Recipients may see both. IT has no way to prevent it or verify what was actually sent.
Most organizations are still managing email signatures manually
According to Exclaimer's State of Business Email Report, only 20% of organizations use a dedicated email signature management solution. The rest rely on employees managing their own or on IT workarounds. For Google Workspace admins working within OU constraints, that gap gets harder to close as the organization grows.

Set a company-wide default email signature
Exclaimer syncs with Google Directory and populates each user's email signature automatically with their name, job title, phone number, and any other attributes you specify.
The Append Footer can't pull from Google Directory. Every user in the OU gets the same static content regardless of their role or details.
Push email signature updates to all users
Update a template in Exclaimer once and it applies to every Workspace user on their next send.
An Append Footer edit only updates that specific OU. Organizations with multiple OUs have to update each one separately. Per-user Gmail signatures are unaffected.
Stop users editing or removing their Gmail signature
Exclaimer adds the approved email signature server-side, in transit, after the message leaves the user's Gmail client.
Per-user Gmail signatures are outside admin control. Users can set, edit, or remove them freely. When both a Gmail signature and an Append Footer are active on the same account, what the recipient sees may differ from what IT configured.
Let marketing manage email signatures without Google Workspace admin rights
Exclaimer gives marketing access to update templates, swap campaign banners, and schedule changes without needing Google Workspace admin rights.
Changing the Append Footer requires admin-level access in the Google Admin Console. There's no way to delegate that to marketing without granting broader admin rights.
How Exclaimer deploys across Google Workspace
Exclaimer connects through a native Google Workspace SMTP relay. Two deployment options used together or independently.
A Gmail integration shows the assigned email signature in the compose window, giving users a preview before the message sends.
Typically run alongside Cloud deployment: compose-window visibility for users, server-side enforcement on every send.

Frequently asked questions
Partially. The Append Footer applies a standard footer server-side, but users can still set their own Gmail signature independently. When both are active, the thread can end up with two separate signature blocks, and IT has no control over either. Exclaimer applies the approved email signature server-side on every send, regardless of what a user has set locally.
Not natively. The Append Footer supports one template per OU. Different departments each need a separate OU, which adds admin overhead as the organization grows. Exclaimer's Signature Rules assign the right email signature from any Google Directory attribute, including department, role, or location, without requiring separate OUs.
Google Workspace has no mechanism to lock a per-user Gmail signature. Users can set, edit, or remove it freely. The only reliable approach is to apply the email signature server-side, after the message leaves the Gmail client, so local settings don't affect what the recipient receives. Exclaimer does this on every send.
Natively, each brand or domain needs its own OU with its own Append Footer to maintain separately. Exclaimer manages email signatures across multiple domains and brands from one console, with separate template sets per entity.
The Append Footer setting in the Google Admin Console lets administrators add a standard block of text to all outbound mail for users in an organizational unit. It applies the same text to everyone with no routing by jurisdiction or business unit. Whether it meets your compliance obligations is a legal question, not a technical one. Exclaimer routes disclaimers by jurisdiction or business unit and applies them automatically on every outbound message.
The Append Footer adds content to the bottom of the full email thread on every reply, not directly under the latest message. Exclaimer applies email signatures server-side, positioned under the latest reply on every outbound message, consistently across all Gmail clients including mobile.
Per-user Gmail signatures are managed in Gmail Settings under the General tab, where each user creates and edits their own. For a company-wide footer, an administrator sets an Append Footer in the Google Admin Console under Apps > Google Workspace > Gmail > Advanced settings. Neither option gives IT central visibility or control over what individual users actually send. Exclaimer manages all email signatures from one console, with updates applied automatically across every Google Workspace user.
