# Fixing duplicate email signatures in Google Workspace

## Overview

This article explains why duplicate email signatures appear in Google Workspace with Opensense Stamping, and how to resolve them by turning off local Gmail signatures.

## Why duplicate signatures happen

Duplicate signatures occur when a user has a local Gmail signature turned on **and** Opensense Stamping is active. Gmail adds a signature when the email is composed, and Opensense adds a signature during mail flow, which results in two signatures.


## Turn off your Gmail signature

1. In Gmail, select **Settings** (the gear), then **See all settings**, and stay on the **General** tab. Scroll to **Signature**. Or [open your Gmail signature settings](https://mail.google.com/mail/u/0/#settings/general) directly.
2. Under **Signature defaults**, set both **For new emails use** and **On reply/forward use** to **No signature**.
3. Optional: if multiple signatures are listed, delete them, so they can't be selected again.
4. Scroll to the bottom of the page, and select **Save Changes**.

:::caution[Save your changes]
Gmail doesn't apply updates unless you select **Save Changes** at the bottom of the Settings page.

## Still seeing duplicate signatures?

If duplicate signatures persist after you update your Gmail settings, check these:

<dl class="kb-insights-summary">
  <div><dt>The Gmail mobile signature (iOS and Android)</dt><dd>In the Gmail app, tap the menu (☰) in the upper-left corner, scroll down and select <strong>Settings</strong>, choose your email account (if you have more than one), tap <strong>Signature settings</strong>, and turn off <strong>Mobile Signature</strong>. Gmail then stops adding a separate mobile signature, so only the Opensense-stamped signature appears.</dd></div>
  <div><dt>Other email clients and apps</dt><dd>Make sure that other email clients or third-party applications aren't adding signatures.</dd></div>
  <div><dt>Gmail compliance footers</dt><dd>Check whether domain-level Gmail compliance footers are adding signature-like content.</dd></div>
</dl>
