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 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.

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:

The Gmail mobile signature (iOS and Android)

In the Gmail app, tap the menu (☰) in the upper-left corner, scroll down and select Settings, choose your email account (if you have more than one), tap Signature settings, and turn off Mobile Signature. Gmail then stops adding a separate mobile signature, so only the Opensense-stamped signature appears.

Other email clients and apps

Make sure that other email clients or third-party applications aren't adding signatures.

Gmail compliance footers

Check whether domain-level Gmail compliance footers are adding signature-like content.
