Email signature - Gmail on Android

UPDATE: Automatic synchronisation from the Web version - 2025


Since the early 2025 updates, Gmail for Android has harmonised the way it works. The HTML signature configured on your computer is now automatically synchronised on your mobile application.

👉 What you get:

  • Logos & Images: Faithful display ✅
  • Clickable links**: Perfectly functional ✅
  • Cleanliness**: No more [OBJ] type tags ❌
  • Simplicity**: No more manual copy and paste on your phone ❌

⚠️ The golden principle: The web version is your "source of truth". The local mobile signature takes priority; if activated, it blocks synchronisation of the rich signature.


💻 Step 1: Configure the "Master" signature on your computer

Everything starts here. To render impeccably on Android, your signature must be set up correctly on the browser.

  1. Connect to Gmail on your computer.
  2. Click on the icon Settings ⚙️View all settings.
  3. In the General tab, scroll down to the Signature section.
  4. Create or modify your signature.

🔥 Warning: Default values

Just below the signature editor, you must configure these options:

  • For new emails: Select your signature.
  • For replies/forwards**: Select your signature.

**Don't forget to click on "Save changes" at the bottom of the page.


🧹 Step 2: Clean up the Gmail application on Android

To make room for the HTML signature, you'll need to remove the "Mobile Signature" that acts as a lock.

  1. Open the Gmail application on your smartphone.
  2. Press the menu → Settings.
  3. Select the relevant email account.
  4. Press Mobile signature.
  5. Delete all the text. The field must be completely empty.
  6. Confirm with OK.

💡 Did you know? In 2025, Gmail will now display an explanatory text: If this field is empty, the signature configured on the Web will be used " This is exactly what we want.


🔄 Step 3: Force synchronisation (if there's a delay)

If the rich signature does not appear immediately when you write a new message :

  1. Go to Settings on your Android phone.
  2. Go to Passwords and Accounts (or "Users and Accounts").
  3. Select your Google Account.
  4. Check that Gmail synchronisation is activated.
  5. Press the three dots Sync Now.

*Note: restarting the application (force shutdown) is usually enough to refresh the display.


✅ Expected end result

  • An identical HTML signature on PC and Android.
  • Images displayed without error.
  • Simplified maintenance: edit on PC, it's updated everywhere.
