Gmail Email Signature Setup: Step-by-Step Tutorial with Templates

TL;DR: To add an email signature in Gmail, go to Settings (gear icon) > See all settings > General > Signature. Create a new signature, add your information, and set it as default for new emails and replies. Save changes at the bottom of the page.

Gmail is the world's most popular email platform, used by over 1.8 billion people. Whether you use a personal Gmail account or Google Workspace for business, adding a professional signature takes just a few minutes.

This guide walks you through every step, from basic setup to advanced customization.

How to Create a Gmail Signature (Desktop)

Step 1: Open Gmail Settings

1. Go to mail.google.com and sign in
2. Click the gear icon in the upper right corner
3. Click See all settings

Step 2: Navigate to Signature Section

1. Make sure you're on the General tab
2. Scroll down to find the Signature section
3. Click Create new

Step 3: Name Your Signature

Give your signature a descriptive name like:

• "Work - Full"
• "Personal"
• "Reply Only"

This name is only visible to you and helps manage multiple signatures.

Step 4: Design Your Signature

Use Gmail's built-in editor to add:

Text formatting:

• Bold, italic, underline
• Font size (small, normal, large, huge)
• Text color and highlight
• Alignment (left, center, right)

Content to include:

• Your full name
• Job title
• Company name
• Phone number
• Website URL (highlight text, click link icon)

Images:

• Click the image icon in the toolbar
• Upload from computer or paste URL
• Resize by clicking and dragging corners

Step 5: Set Default Signatures

Below the editor, you'll see dropdown menus:

"For new emails use:" Select your full signature

"On reply/forward use:" Select a shorter signature or "no signature"

Step 6: Save Changes

Scroll to the bottom of the settings page and click Save Changes. Gmail will return you to your inbox with the new signature active.

How to Add a Signature to Your Email in Gmail

To add a signature to your email in Gmail, open Gmail on your desktop, click the gear icon in the top-right corner, and select "See all settings." Scroll down to the Signature section under the General tab, then click "Create new" to start building your signature. Type your name, job title, company, and contact details into the text editor. Use the formatting toolbar to add bold text, links, or an image like a company logo. Once you are finished, set your new signature as the default for new emails using the dropdown menu below the editor. You can also choose a different signature for replies and forwards if you prefer a shorter version. Click "Save Changes" at the bottom of the page. Your signature will now appear automatically every time you compose a new email in Gmail, whether you are on desktop or using the synced mobile app.

Adding a Signature to a Personal Gmail Account

Personal Gmail accounts support up to 10,000 characters per signature. Follow these steps:

1. Sign in at mail.google.com
2. Click the gear icon then See all settings
3. Scroll to the Signature section on the General tab
4. Click Create new and give it a name
5. Add your details: name, phone, website, social links
6. Click Save Changes at the bottom

For a polished look, browse email signature examples to find a layout that fits your style.

Adding a Signature to a Google Workspace Account

Google Workspace (business) accounts follow the same steps as personal accounts. The only difference is that your organization admin may also set a company-wide signature through the Admin Console. If an admin-managed signature is active, it appends to your personal one.

1. Open Gmail and go to Settings > See all settings > General > Signature
2. Click Create new
3. Design your signature with company branding
4. Set it as default for new emails and replies
5. Click Save Changes

If your team needs consistent branding across everyone's signatures, a tool like Signkit can help manage that at scale.

Adding Images to Your Gmail Signature

Adding a Company Logo

1. In the signature editor, position your cursor where you want the logo
2. Click the image icon in the toolbar
3. Choose how to add the image:
   • Upload: Select from your computer
   • URL: Paste a web address
   • Drive: Select from Google Drive

Pro tip: For best results, host your logo on your company website and use the URL option. This ensures the image always loads correctly.

Adding a Profile Photo

1. Prepare a square image (200x200px recommended)
2. Upload or link the image
3. Click the image to resize
4. Drag corners to adjust dimensions

Recommended size: 80-100px square for profile photos

Image Troubleshooting

Image not appearing:

• Check if the URL is publicly accessible
• Verify the image isn't too large (under 50KB works best)
• Try a different image format (PNG or JPG)

Image too large:

• Click on the image in the editor
• Drag the corners to resize
• Gmail doesn't offer precise pixel control, so estimate visually

Gmail Signature on Mobile

Gmail App (iOS)

1. Open the Gmail app
2. Tap the menu icon (three horizontal lines)
3. Scroll down and tap Settings
4. Select your email account
5. Tap Signature settings
6. Toggle on Mobile Signature
7. Enter your signature text
8. Tap the back arrow to save

Limitation: The Gmail mobile app doesn't support HTML signatures or images. Your signature will be plain text only.

Gmail App (Android)

1. Open Gmail and tap the menu icon
2. Tap Settings
3. Select your account
4. Tap Mobile Signature
5. Enter your signature text
6. Tap OK

Android tip: For a richer mobile signature, compose emails in the Gmail app but manage signatures in Gmail web on a browser.

Mobile Signature Workaround

To use your full signature on mobile:

1. Create your full signature in Gmail web
2. Set it as default for new emails and replies
3. When composing on mobile, the signature from web settings appears

This works because Gmail syncs signature settings across devices when you use the Gmail app with your account signed in.

How to Change Your Gmail Email Signature

To change your Gmail email signature, go to Gmail settings by clicking the gear icon, then select "See all settings" and scroll to the Signature section under the General tab. Click the name of the signature you want to edit, and the text editor will load its current content. Make your changes directly in the editor, updating text, links, images, or formatting as needed. You can also rename the signature by clicking the pencil icon next to its name. If you want to swap which signature Gmail uses by default, adjust the dropdown menus below the editor for "New emails" and "Replies/forwards." After making your changes, scroll to the bottom of the page and click "Save Changes." The updated signature takes effect immediately on all new emails you compose. If you use multiple devices, your changes sync automatically through your Google account, so both desktop and mobile will reflect the update.

Changing Your Signature on Desktop

1. Open mail.google.com and click the gear icon
2. Select See all settings
3. Scroll to the Signature section on the General tab
4. Click the signature name you want to modify
5. Edit the content in the rich text editor
6. Optionally rename the signature using the pencil icon next to the name
7. Update the default signature dropdowns if needed
8. Click Save Changes at the bottom of the page

Your changes apply instantly to all new emails. Existing drafts keep the old signature unless you manually swap it. If you also use Outlook for work, see our guide on setting up an Outlook signature for a consistent cross-platform experience.

Changing Your Signature on Mobile

The Gmail mobile app supports only plain-text signatures, which are separate from your desktop signature.

On iOS:

1. Open the Gmail app and tap Menu (three lines)
2. Tap Settings then select your account
3. Tap Signature settings
4. Edit the text and tap the back arrow to save

On Android:

1. Open Gmail and tap Menu
2. Tap Settings then select your account
3. Tap Mobile Signature
4. Edit the text and tap OK

Keep your mobile signature shorter since recipients on phones see less screen space. A name, title, and phone number are usually enough. For tips on mobile-friendly formatting, check our Outlook email signature setup guide, which covers similar cross-platform considerations.

Switching Between Multiple Gmail Signatures

If you have more than one signature saved, you can switch between them on a per-email basis:

1. Start composing a new email
2. Click the pen icon (insert signature) at the bottom of the compose window
3. Select the signature you want from the dropdown list
4. The selected signature replaces the current one in the email body

You can also change which signature Gmail inserts by default:

• Go to Settings > General > Signature
• Under "Signature defaults," pick your preferred signature for new emails
• Pick a different one (or none) for replies and forwards
• Click Save Changes

This is useful if you have a detailed signature for first-contact emails and a shorter one for ongoing threads.

Google Workspace Signatures

Individual Setup

Google Workspace users set up signatures the same way as personal Gmail:

1. Open Gmail

Admin-Managed Signatures

Google Workspace admins can set default signatures for the organization:

1. Go to admin.google.com
2. Navigate to Apps > Google Workspace > Gmail > User settings

5. Apply to organizational units

Troubleshooting Common Gmail Signature Issues

Signature Not Appearing

Check default settings:

1. Go to Settings > General > Signature
2. Verify your signature is selected for "New emails"
3. Ensure "On reply/forward use" isn't set to "No signature"

Check compose mode:

1. In Settings > General, find "Default reply behavior"
2. Ensure "Reply" is selected (not "Reply all" issues)

Signature Formatting Changes

Problem: Signature looks different than designed.

Solutions:

• Use web-safe fonts only (Arial, Verdana, Georgia)
• Avoid complex formatting
• Test by sending to yourself

Images Not Displaying

Problem: Recipients see broken image icons.

Solutions:

• Host images on a publicly accessible URL
• Avoid Google Drive links (often blocked)

Signature Too Long

Problem: Gmail warns about signature length.

Solutions:

• Reduce image file sizes

Solutions:

1. Check if you have signature set for both "new emails" AND "replies"

Frequently Asked Questions

How do I add a logo to my Gmail signature?

In Gmail signature settings, click the image icon in the editor toolbar. You can upload an image from your computer, paste an image URL, or select from Google Drive. For best results, use a URL from your company website and keep the logo under 200px wide.

Can I have different signatures for different Gmail accounts?

Yes. If you have multiple Gmail accounts, each has its own signature settings. Open Gmail for each account, go to Settings > General > Signature, and create signatures for that specific account. You can also add multiple signatures within each account for different purposes.

Why does my Gmail signature look different when received?

Gmail signatures can render differently in other email clients (Outlook, Apple Mail). Use web-safe fonts, avoid complex formatting, and test by sending emails to friends using different email platforms. Table-based HTML signatures tend to be more consistent.

How do I add a signature on the Gmail mobile app?

Open the Gmail app, tap Menu > Settings > [your account] > Mobile Signature (or Signature settings on iOS). Note that mobile Gmail only supports plain text signatures. For HTML signatures with images, create them in Gmail web, where they'll sync to your mobile-composed emails.

Can my organization control Gmail signatures for everyone?

Yes, Google Workspace admins can set organization-wide signatures through the Admin Console (admin.google.com). Go to Apps > Google Workspace > Gmail > User settings > Signature. However, admin-managed signatures have limited formatting options compared to third-party tools.
