How to Add a Signature in Gmail (Step by Step)

To add a signature in Gmail, open Gmail, click the gear icon in the top right, choose See all settings, scroll down to the Signature section on the General tab, click Create new, give it a name, type or paste your signature, set it as the default for new emails and replies, then click Save Changes at the bottom. The same steps work on the web in minutes, and the Gmail mobile app has a simpler text-only version. With makemysig you can design a polished, on-brand signature first and paste it straight into this screen.

This guide covers the exact clicks on desktop and mobile, how to add a clickable logo and links, and the common reasons a signature does not show up or looks broken. By the end you will have a signature that appears automatically on every message and looks right on any device.

How do I add a signature in Gmail on desktop?

Open Gmail in your browser and click the gear icon in the top-right corner, then select See all settings. On the General tab, scroll until you reach the Signature section. Click Create new, type a label such as "Work" so you can recognize it later, and confirm. A text box appears where you build the signature itself.

Type your name, role, company, and one primary contact method into the box. Use the small formatting toolbar to adjust font, size, color, and to insert links or an image. Just below the editor you will see Signature defaults, where you choose which signature is used for new emails and which is used for replies and forwards. Finally, scroll all the way to the bottom of the page and click Save Changes. This last step is the one people miss most often, and without it nothing is saved.

How do I add a clickable logo and links?

To add an image, place your cursor in the signature box and click the image icon in the toolbar. You can upload a file or insert one by URL, but a hosted image at a stable web address is the most reliable because it loads the same way for every recipient. Keep the logo small, around 100 to 150 pixels wide, so it does not overwhelm the text.

To make any text or image clickable, select it and click the link icon, then paste the destination URL. This is how you turn a website line into a real link or point your logo at your homepage. Designing the layout outside Gmail and pasting it in usually gives you cleaner results, because the built-in editor offers limited control over spacing and alignment.

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

Open the Gmail app on your phone, tap the menu icon in the top left, and scroll down to Settings. Choose the account you want, then tap Mobile Signature (or Signature settings on some versions). Type your signature and save. Note that the mobile signature is plain text only: it cannot hold a logo, colors, or clickable links, and it is completely separate from the signature you set on the web.

Because of this limit, many people keep a short text line on mobile and rely on their full designed signature on desktop. If a consistent look across every device matters to you, building the signature in a dedicated tool and managing it centrally avoids the patchwork of mismatched mobile and desktop versions.

Why is my Gmail signature not showing up?

The most common cause is forgetting to click Save Changes at the bottom of the settings page, so the signature is never stored. The second is leaving Signature defaults set to No signature, which means Gmail has a signature on file but never inserts it automatically. Set defaults for both new emails and replies to fix this.

If you use more than one address in Gmail, remember that signatures are assigned per account, so check that you edited the right one. And if your signature shows on desktop but not on your phone, that is expected: the web and mobile signatures are managed separately, as covered above.

How do I keep my Gmail signature consistent and on brand?

Pasting a designed signature is the easiest way to keep fonts, colors, and your logo intact, because the Gmail editor can quietly strip or alter formatting when you type directly. Avoid pasting a screenshot of your signature as one large image, since it breaks when resized, fails accessibility, and looks blurry on high-resolution screens. Build it from real text and a small hosted logo instead.

For teams, the challenge is making sure everyone uses the same layout, colors, and current job titles. Centralizing the template means one update reaches everyone at once, so nobody is still sending last year's branding. That consistency is what turns a routine sign-off into a recognizable brand touchpoint on every message.

Frequently asked questions

Can I have more than one signature in Gmail?

Yes. Gmail lets you create multiple signatures and switch between them. Use Create new in the Signature section to add each one, then pick which is the default for new emails and replies. While writing a message, you can also swap signatures using the pen icon in the toolbar.

Why does my Gmail signature look different for recipients?

Email clients render formatting differently, so a signature can shift depending on where it is opened. Keep the design simple, use web-safe fonts with fallbacks, host your logo at a stable URL, and send yourself a test email to a couple of different accounts before relying on it.

How do I add a signature with social media icons in Gmail?

Gmail has no built-in social icon feature, so you add each icon as a small linked image: insert the icon image, then link it to your profile. Building the signature in a dedicated editor and pasting it in is far quicker, because the icons and links come ready-made and correctly spaced.

Will my Gmail signature appear on replies and forwards?

Only if you set it to. In the Signature defaults area, choose your signature for the "on reply/forward" option as well as for new emails. Many people set a fuller signature for new messages and a shorter one for replies to avoid repetition in long threads.
