Your email signature is one of the first things people notice in your messages. Whether you're starting a new job, updating your contact details, or just want a more professional look, knowing how to change your email signature in Gmail is essential.
This guide walks you through the entire process on both desktop and mobile, with tips to make your signature stand out.
How to Change an Email Signature in Gmail on Desktop
Open Gmail Settings
Go to mail.google.com and sign in. Click the gear icon in the top-right corner, then click "See all settings".
Find the Signature Section
You'll land on the General tab. Scroll down until you see the "Signature" section. This is where Gmail stores all your signatures.
Create or Edit Your Signature
Click "Create new" to add a new signature. Give it a name (e.g., "Work" or "Personal"). If you already have one, click on it to start editing.
Format Your Signature
Use the formatting toolbar to customize your signature. You can:
- Change font style, size, and color
- Add bold, italic, or underlined text
- Insert images (like your company logo or headshot)
- Add hyperlinks to your website or social profiles
Set Signature Defaults
Below the editor, use the dropdown menus to assign your signature:
- For new emails: Select the signature to use when composing a new message.
- For replies/forwards: Choose a signature (or "No signature") for replies and forwarded messages.
Save Changes
Scroll to the very bottom of the settings page and click "Save Changes". Your new signature will now appear in all outgoing emails.
How to Change Signature in Gmail Email on Mobile
The Gmail mobile app has a simpler signature editor than the desktop version. Here's how to update it:
Open the Gmail App
Launch the Gmail app on your iPhone or Android device. Make sure you're signed into the correct account.
Go to Settings
Tap the hamburger menu (three horizontal lines) in the top-left corner, then scroll down and tap "Settings".
Select Your Account
If you have multiple accounts, tap the email address you want to update the signature for.
Edit Mobile Signature
Tap "Mobile Signature". Type or paste your new signature text. Note: the mobile editor only supports plain text — no images or HTML formatting.
Save
Tap "OK" to save your mobile signature. It will be appended to all emails sent from the Gmail app.
Tips for a Professional Email Signature
- Keep it concise. Include your name, title, company, phone number, and one or two links. Avoid walls of text.
- Use a consistent design. Match your signature colors and fonts to your brand for a cohesive look.
- Optimize images. If you include a logo or headshot, keep file sizes small and dimensions reasonable (no wider than 600px).
- Add social links. Include icons linking to your LinkedIn, Twitter, or company website.
- Test across clients. Send a test email to yourself and check how it looks in Gmail, Outlook, and on mobile.
- Use a signature generator. Tools like our free email signature generator let you create a polished, HTML-formatted signature without any coding.
