How to Add a Signature in Gmail

This guide walks you through creating and inserting an email signature in Gmail on both desktop and mobile. You’ll learn how to set up a professional sign-off with your name, contact details, and even a logo, so every email you send looks polished without extra effort.

What You’ll Need

• A Gmail account (free or through Google Workspace)
• Access to Gmail in a web browser (on desktop) or the Gmail app (on mobile)
• Optional: a logo or image file (e.g., PNG or JPG) if you want to include a graphic

Step-by-Step

On Desktop (Web Browser)

1. Open Gmail and sign in if you haven’t already.
2. Click the gear icon (Settings) in the top-right corner, then select “See all settings.�
3. Scroll to the “Signatureâ€� section. If you don’t see it, make sure you’re on the “Generalâ€� tab.
4. Click “Create new� and give your signature a name (e.g., “Work� or “Personal�). This is only for your reference.
5. In the text box that appears, type your signature. You can use the toolbar to format text, add links, or insert images (like a logo).
6. To add an image, click the “Insert image� icon (the mountain-like icon), upload your file, and adjust its size if needed.
7. Once you’re happy with the content, scroll down and click “Save Changes.â€�
8. When composing a new email, your signature will appear automatically. If you want it in a reply or forwarded message, check the box next to “Insert this signature before quoted text in replies and remove the line that precedes it.� (Optional but recommended.)

On Mobile (Gmail App for Android and iOS)

1. Open the Gmail app on your phone or tablet.
2. Tap the hamburger menu (three horizontal lines) in the top-left corner.
3. Scroll down and tap “Settings.�
4. Choose the email address you want to add a signature to (if you have multiple accounts).
5. Tap “Signature� (on iOS it might be under “Signature settings�).
6. Type your signature in the text field. You can use basic formatting like bold or italics, but you cannot insert images on mobile.
7. Tap “OK� or “Done� (depending on your device) to save.

Common Mistakes

• Forgetting to save: On desktop, you must scroll down and click “Save Changesâ€� – many users close the tab and lose their work.
• Using too many images: Large logos can make your email look cluttered and may be blocked by some email clients. Keep images small (under 100px tall is a good rule).
• Not updating after a job change: If you change your phone number or job title, your old signature will keep appearing unless you edit it.
• Adding a signature to replies when you don’t want it: On desktop, you can control this with the checkbox for replies; on mobile, the signature is added to all emails by default.
• Using a signature that’s too long: A signature with 10 lines of contact info is overwhelming. Keep it concise – name, title, phone, email, maybe a website.

Tips

• Use a professional font: Stick to common fonts like Arial, Calibri, or Verdana. Unusual fonts may not render on the recipient’s device.
• Include a call-to-action: If you want people to check your website or LinkedIn, add a link. But don’t overdo it – one or two links max.
• Add a separator line: A simple “—â€� or a horizontal line above your signature makes it look tidy.
• Test on multiple devices: Send a test email to yourself and check how it looks on your phone, a PC, and a Mac. Formatting can vary.
• Use the same signature everywhere: If you also use Outlook or Apple Mail, try to match your Gmail signature so your brand is consistent.

Troubleshooting

• Signature not showing up: Make sure you’ve actually typed something in the signature box. Also, check that you haven’t accidentally left the signature blank or deleted it. On desktop, ensure you clicked “Save Changes.â€�
• Signature appears on new emails but not replies: On desktop, go to Settings > General > Signature and check the box that says “Insert this signature before quoted text in replies.â€� On mobile, this isn’t an option – the signature is added to all emails.
• Image not displaying: If your logo isn’t showing, try re-uploading it. Make sure the file is a common format (PNG, JPG) and under 10MB. Some email providers block images from unknown senders, so the recipient may need to enable image loading.
• Formatting looks wrong: If your signature looks fine in Gmail but messy in Outlook, it’s likely due to HTML differences. Simplify your signature – remove tables or complex styling. You can also try composing in plain text (but you’ll lose formatting).
• Can’t find the signature settings on mobile: On iOS, the option is under “Signature settingsâ€� within the account settings. On Android, it’s simply “Signature.â€� If you don’t see it, make sure you’re looking at the correct account.

Frequently Asked Questions

Can I have multiple signatures in Gmail?

Yes, on desktop you can create multiple signatures and assign them to different email addresses (if you have multiple accounts) or choose which one to use per email. On mobile, you can only have one signature per account.

How do I add a signature to only one email, not all?

On desktop, when composing an email, you can click the “Insert signatureâ€� icon (the pencil with a line) and select a different signature or “None.â€� On mobile, you can’t do this – the signature is added automatically.

Can I use HTML in my Gmail signature?

Gmail’s signature editor doesn’t allow direct HTML editing, but you can copy-paste HTML from another source (like an email signature generator) into the signature box. It will render as formatted text.

Why is my signature not showing on my phone?

Make sure you’ve saved the signature in the Gmail app settings for that specific account. Also, check that you’re using the Gmail app, not the default email app on your phone.

How do I delete a signature in Gmail?

On desktop, go to Settings > General > Signature, click the pencil icon next to the signature name, then click the trash icon. On mobile, go to Settings > (your account) > Signature, clear the text, and tap OK/Done.

Can I add a signature to emails I send from my phone’s default email app?

No, this guide is for the Gmail app. If you use a different email app, you’ll need to set up your signature in that app’s settings. The steps are similar but not identical.
