How to Add Signature in Gmail (Desktop)
Follow these simple steps to add your email signature in Gmail:
Step 1: Open Gmail Settings

2. At the top right corner, click the Settings gear icon
3. Click "See all settings" from the dropdown menu
Step 2: Navigate to the Signature Section
In the Settings page, scroll down until you find the "Signature" section. This is where you'll create and manage all your Gmail signatures.
Step 3: Create Your Signature
In the Signature section, you have two options:
- Create a new signature from scratch: Click "Create new" to start with a blank signature
- Use a signature generator: Create your signature using a professional email signature maker for Gmail, then paste it into the signature box
Tip: Your image also counts toward the character limit. If you get an error, try to resize the image.
Step 4: Configure Signature Defaults
Below your signature editor, you'll find "Signature defaults" settings:
- For new emails: Select which signature to use for new messages
- On reply/forward: Choose whether to include your signature when replying to or forwarding emails
If you want your signature to appear only on certain types of messages (such as new messages or replies/forwards), navigate under "Signature defaults" and make your selection.
Step 5: Save Your Changes
Once you're happy with your email signature block, scroll down to the bottom of the settings page and click "Save Changes".
To see your professional email signature in action, compose a new email. Your email signature should automatically appear at the end of your email.
That's it! Your new email signature is now added to Gmail and will be included in any new emails you send.
📊 Gmail Signature Character Limit (2026 Update)
Gmail allows up to 10,000 characters in your email signature. This limit includes:
• All text content
• HTML code (if using HTML signatures)
• Image data (embedded images count toward the limit)
Common Issues:
If you see an error message when saving your signature, try:
1. Resize images to smaller dimensions
2. Compress image files
3. Remove unnecessary formatting or whitespace
4. Use image URLs instead of embedding images directly
Understanding Gmail Signature Settings
Gmail offers several signature settings to customize how and when your signature appears.
Signature Defaults
Located below your signature editor, "Signature defaults" controls:
• For new emails: Choose which signature to use for new messages
• On reply/forward: Select whether to include your signature when replying or forwarding emails
• Insert signature before quoted text: Check this to place your signature above the original message in replies
Multiple Account Settings
If you have multiple Gmail accounts, you'll need to configure the signature for each account separately. Switch accounts in Settings to manage each signature individually.

Why is my signature not showing up in the Gmail app?
If your Gmail signature isn't appearing on your mobile device:
• Make sure "Mobile Signature" is toggled ON in settings

• Check that you're editing the signature for the correct email account (if you have multiple)
Mobile Signature Limitations:
• No images or logos: Mobile signatures are text-only
• No HTML formatting: You can't add custom fonts, colors, or HTML code
• Separate from desktop: Your desktop signature and mobile signature are managed separately
