# Server-side installation

In some cases, client-side signature insertion isn’t possible. For example, Apple Mail IOS or Gmail on Android don't support client-side installation, or certain security policies may block client-side deployment. That’s why we offer the server-side signature feature to install signatures across all email clients and devices.

When server-side insertion is enabled, outgoing emails are routed through Scribe’s secure mail servers, where we detect whether a signature should be applied, inject it if needed, and then return the message to Google or Microsoft for final delivery, ensuring your emails remain fully secure and confidential. All processing happens in transit, without storing message content, and final delivery is handled by your email provider to preserve full deliverability and trust.

### FAQ

**Do I see my signature when I compose an email when using server-side set-up?**

No, you don't see your signature when composing an email, as the signature is applied after your email is sent.

#### Can I combine client-side integrations and server-side integrations?&#x20;

Yes, you can combine both types of integrations. This allows you to connect Google Workspace or Microsoft 365 through client-side integration to see your signature when composing emails, while using server-side integration for signatures on email clients like Apple Mail, which don't work with client-side integrations.

### Notes

* If no signature is found for the sender, the message is relayed as-is through the Google/Microsoft SMTP relay.
* If something wrong is happening on the scribe server (error when processing the email, server not available, ...) we don't store your email, we use the Google or Microsoft retry mechanism.
* The server side integration is compatible with all client side integrations. We detect if the email already contains the Scribe signature to avoid double signature.&#x20;
