Gmail Signature Troubleshooting

Updated this week

There could be several reasons why your Gmail signature isn’t showing up. Here’s a breakdown of all possible causes along with ways to fix them.

1. Incorrect Signature settings

The first and foremost cause of the Gmail email signature not showing up is incorrect signature settings. Sometimes, users may forget to turn on the signature feature, or they may not have saved the changes properly.

How to check the Signature settings:

  1. Open Gmail and click on the Gear icon on the top right corner of your screen.

  2. Select “See all settings” from the drop-down menu.

  3. Scroll down to the “Signature” section.

  4. Make sure the signature feature is turned on and the correct signature is selected.

2. Gmail composer is set to “No signature”

If your Gmail composer is set to “No Signature," you won't see your signature in your emails.

You can change it by following these steps:

  1. Click on the gear icon in the upper right corner to go to “Settings.”

2. In the dropdown menu, click on “See all settings.”

3. On the “Settings” page, click on the “General” tab.

4. Scroll down to the “Signature” section. If it’s set to “No Signature," select the option “My signature.”

3. You didn’t add a default signature

If you did not mark at least one signature as the default for your Gmail account, then your emails will not display a signature.

How to set your Gmail signature as the default:

1. In the top right corner of Gmail, click the gear icon and select “See all settings.”

2. In the General tab, scroll down to the Signature section and click “Create New.”

3. Paste (Ctrl+V) your signature into the text box.

4. Optional Editing: Use the tT icon to change font size or the A icon to adjust text colors to match your brand. Stick to email-safe fonts like Sans Serif to ensure consistency.

5. Set Defaults: Under Signature defaults, select your signature for both New Messages and Reply/Forward use.

4. Browser or App issues

If your browser is not updated, or if there’s an issue with cookies and cache, it can interfere with Gmail’s functionality, including showing signatures.

To fix browser-related issues that might be causing your Gmail signature not to show:

  1. Update Browser: Ensure your browser is up-to-date. Usually, you can check this in the browser’s settings or help menu. If an update is available, install it and restart your browser.

  2. Clear Cache and Cookies: Go to your browser’s settings, find the option to clear browsing data (usually under “Privacy and security” or similar), make sure to check the boxes for cookies and cache, and then clear the data. Remember that this might log you out of most websites.

  3. Disable Extensions: If you have any browser extensions installed, they might be interfering with Gmail. Try disabling them one by one to see if this solves the problem. You can usually manage extensions in your browser’s settings.

  4. Try Another Browser: If none of the above steps work, try accessing Gmail in a different browser to see if the problem persists.

Remember to restart your browser or even your computer after each step to make sure changes take effect.

5. Gmail’s composer is set to plain text

If your Gmail is set to “Plain Text Mode," it will not support rich text features or images in your signature. Here’s how you can switch off “Plain Text Mode”

How to fix:

  1. Log into your Gmail account and click on “Compose” to start a new email.

  2. In the lower-right corner of the “New Message” window, click on the three dots (More options).

  3. If “Plain text mode” is checked, click on it to uncheck and disable this mode.

6. Incorrect Gmail signature format

If the signature has been formatted incorrectly, for instance, using unsupported HTML, it might not show up in the emails.

To correct issues related to signature formatting in Gmail, follow these steps:

  1. Log into your Gmail account and go to “Settings” by clicking the gear icon in the upper-right corner.

  2. Click on “See all settings”, then go to the “General” tab.

  3. Scroll down to the “Signature” section. Click on the signature that’s causing the problem to edit it.

  4. Re-insert Images: Click the Insert Image (mountain icon) to link your logo; never drag-and-drop or paste images directly as they will break.

  5. Use Web-Safe Fonts: Highlight your text and select Verdana, Tahoma, or Georgia from the font menu to ensure compatibility across all devices

  6. Use Basic HTML Only: Stick to the toolbar buttons for Bold, Italics, and Links to avoid Gmail stripping out complex or unsupported code.

  7. Clear Hidden Formatting: If the layout is messy, highlight the signature and click the Remove Formatting (Tx icon) to strip out "junk" code from previous pastes.

  8. Save Changes: You must scroll to the very bottom of the page and click Save Changes or your updates will not be applied.

Remember that the appearance of your signature can vary depending on the email client used by the recipient, so it’s best to keep it simple and universally compatible.


More troubleshooting suggestions for Gmail signatures not showing

The above-mentioned steps should be sufficient for solving 85% to 90% of Gmail signatures not showing up issues. If after completing the above steps your Gmail signature is still not visible you can try the following:

1. Conflicts with extensions or Add-Ons

Certain browser extensions or add-ons can interfere with Gmail and cause the signature not to appear.

To disable your browser extensions:

  1. Open your browser and click on the three-dot icon on the top right corner of your screen.

  2. Select “More tools” from the drop-down menu.

  3. Click on “Extensions.”

  4. Disable all extensions by toggling the switch off

2. Use incognito mode

Gmail Signature still not visible? Try using your browser in incognito mode.

To use your browser in incognito mode:

  1. For Google Chrome: Click the three dots in the top right corner of the browser. From the dropdown menu, select “New Incognito Window”. Alternatively, you can use the shortcut Ctrl+Shift+N (or Command+Shift+N on a Mac).

  2. For Mozilla Firefox: Click the three lines in the top right corner of the browser. From the dropdown menu, select “New Private Window”. Alternatively, you can use the shortcut Ctrl+Shift+P (or Command+Shift+P on a Mac).

  3. For Safari: Click “File” in the top left corner of the browser, then select “New Private Window”. Alternatively, you can use the shortcut Command+Shift+N.

Once in incognito or private mode, navigate to the Gmail website and log in to your account to check if your signature is now visible. This mode ensures that no extensions are active and no cookies or cache data are affecting your session, which could help if these were causing issues with your Gmail signature.

If you are using the Gmail app, make sure that it is up to date.

To check for app updates:

  1. Open the Google Play Store or Apple App Store on your mobile device.
