How to Add a Signature in Gmail and Outlook: The Complete 2026 Guide

An email signature is the small block of text and images at the bottom of your messages that shares your name, role, company, and contact details. It does quiet but real work: it makes you look professional, saves you from retyping the same details, and gives every recipient an easy way to reach you. With hundreds of billions of emails sent every day and the large majority of professionals using a signature, skipping one means leaving easy impressions on the table.

The good news is that both Gmail and Outlook let you set up a signature once and have it appear automatically on every message. This guide walks through how to add a signature in Gmail and Outlook across desktop, web, and mobile, plus how to add a logo or a handwritten signature image so your sign-off looks polished. Every step below reflects how these platforms work in 2026.

What Makes a Good Email Signature

Before the steps, it helps to know what belongs in a signature. A clean, useful sign-off usually includes your full name, job title, company, a phone number, your website, and maybe a single social link or logo. The trick is restraint. A signature crammed with five phone numbers, three quotes, and a wall of icons looks cluttered and distracts from the message.

A strong signature tends to share a few qualities:

• It is concise. Three to five lines of text is plenty for most people.
• It is consistent. The same fonts and colors appear in every message you send.
• It is readable. Dark text on a plain background beats bright colors that strain the eyes.
• It works everywhere. It renders correctly whether the recipient opens it in Gmail, Outlook, or on a phone.
  
  

Keep those in mind as you build yours, and the setup steps below will give you a signature that looks sharp in any inbox.

How to Add a Signature in Gmail on Desktop

Setting up a Gmail signature on a computer takes about two minutes, and the process is identical whether you use a personal Gmail account or Google Workspace.

Here is how to do it:

1. Open Gmail and click the gear icon in the top-right corner.
2. Click See all settings.
3. You will land on the General tab. Scroll down to the Signature section.
4. Click + Create new, give the signature a name such as “Work,” and click Create.
5. In the editing box, type your details and use the toolbar to adjust fonts, sizes, colors, links, and images.
6. Under Signature defaults, choose which signature applies to new emails and which applies to replies and forwards. Most people set the same one for both.
7. Scroll to the very bottom of the page and click Save Changes.
   
   

That last step matters. Gmail does not save your signature until you click Save Changes at the bottom of the settings page, and it is the step people most often forget. Once saved, your signature appears automatically on every message you compose from Gmail on desktop.

If you want your signature to look designed rather than plain text, a free email signature template generator can produce a clean, formatted block you paste straight into the Gmail editor. It handles the layout and spacing so your name, title, and contact details line up neatly.

How to Add a Signature in Gmail on Mobile

Gmail’s mobile signature is separate from your desktop one and does not sync between them, so you set it up on its own. The mobile signature is text-only, so keep it short.

To add it:

1. Open the Gmail app and tap the menu icon (three lines) in the top-left corner.
2. Scroll down and tap Settings.
3. Select the email account you want to set up.
4. Tap Mobile Signature (or Signature settings).
5. Type your signature text and tap OK or Save.
   
   

Because the mobile signature is plain text, stick to your name, title, and maybe a phone number. Save the formatted, image-rich version for desktop.

How to Add a Signature in Outlook on the Web and Outlook.com

The web version of Outlook and Outlook.com share the same path to signature settings, and it is one of the simpler setups.

Follow these steps:

1. Open Outlook on the web and click the gear icon in the top-right corner.
2. Click View all Outlook settings at the bottom of the panel.
3. Choose Mail, then Compose and reply.
4. Scroll to the Email signature section.
5. Give your signature a name, then type and format it in the editor.
6. Use the dropdowns to set it as the default for new messages and for replies and forwards.
7. Click Save.
   
   

Your signature will now drop into messages automatically based on the defaults you chose. The web editor supports text formatting, links, and images, so you can build a fairly polished signature here.

How to Add a Signature in the Outlook Desktop App

The classic Outlook desktop app for Windows keeps signature settings in a slightly hidden spot, and you reach them from inside a message window.

For Windows:

1. Open Outlook and click New Email to open a message window.
2. In the message window, click the Insert tab in the ribbon.
3. Click Signature, then Signatures from the dropdown.
4. In the Signatures and Stationery window, click New under the Email Signature tab.
5. Name the signature, then type and format your content in the edit box.
6. Under Choose default signature, pick which account it applies to and set it for new messages and replies.
7. Click OK.
   
   

For Outlook on Mac:

1. Open Outlook and go to the Outlook menu, then Settings (or Preferences).
2. Under Email, click Signatures.
3. Click the + icon to create a new signature.
4. Name it, type your content, and format it with the toolbar.
5. Use the Choose Signature dropdown to set it as the default for each account.
   
   

Once saved, your signature appears automatically based on the defaults you set, just like the web version.

How to Add a Logo or Image to Your Email Signature

Adding a logo or a small image lifts a signature from plain to professional. In both Gmail and Outlook, you add an image through the signature editor’s image button, then upload the file or paste a link to it.

A few pointers for images in signatures:

• Keep the file small so it loads quickly and does not weigh down your emails.
• Use a transparent PNG for logos so they sit cleanly on any background color.
• Resize the image inside the editor so it does not dominate the signature.
• Test the signature by emailing yourself to check how it renders.
  
  

If you want a ready-made, well-formatted signature with room for a logo and contact icons, an email signature generator with 100+ pro templates gives you a starting point you can customize and paste into either platform. For something more tailored, a signature design generator tool lets you adjust colors, layout, and fields until the block matches your brand.

How to Add a Handwritten Signature Image to Your Email

Some people like to end emails with an image of their actual handwritten name for a personal touch, especially for client-facing or sales messages. This is simply an image added to your signature, so the steps are the same as adding a logo: create a transparent PNG of your signature and insert it through the editor.

The cleanest way to get that image is to generate it rather than scan it. A free handwritten signature generator produces a transparent, sharp signature with no paper shadows, which then displays correctly on any background color your recipient sees. You can also create one with eSignaturely, which is free and needs no registration. Enter your initials on the form to generate a styled signature, or draw your own unique signature by hand, then save the image and drop it into your Gmail or Outlook signature.

Keep the handwritten image small and place it above your typed name and title, so recipients still get your details in selectable, searchable text.

Tips for a Signature That Works Everywhere

Gmail and Outlook use different rendering engines, which means a signature that looks perfect in one can shift in the other. A few habits keep yours consistent:

• Favor simple formatting. Heavy HTML and complex tables often break across clients.
• Avoid pasting from word processors. They smuggle in hidden formatting that causes spacing issues.
• Host images reliably. Broken image links leave an ugly placeholder box.
• Test before you rely on it. Send the signature to a Gmail address and an Outlook address and check both.
• Keep contact details as text. Putting your phone and email in plain text, not just an image, keeps them clickable and searchable.
  
  

Which Setup Should You Use?

If you mainly work on a computer, set up the full formatted signature on Gmail desktop or in your Outlook app, with a logo or handwritten image if you want one. If you send a lot of email from your phone, add a short text-only mobile signature too, since it does not sync from desktop. And if you switch between Gmail and Outlook, build the signature with a generator that outputs clean, cross-compatible formatting so it looks the same in both.

The goal is a sign-off you set once and never think about again. Build it carefully, save it in each place you send mail, and every message you send will close with a polished, professional signature.

Conclusion

Adding a signature in Gmail and Outlook is quick once you know where the settings live. In Gmail, head to See all settings, then the Signature section, and remember to click Save Changes. In Outlook, use the gear menu on the web or the Insert tab in the desktop app. On mobile, set up a short text signature separately. Adding a logo or a handwritten signature image is just a matter of inserting a clean PNG through the editor.

The smartest approach is to design one polished signature, generate any images you need as transparent files, and apply it everywhere you send email. Set it up properly once, and every message you send will look professional without any extra effort.
