A Gmail email signature generator builds a formatted signature you can paste directly into Gmail’s settings. This guide covers how to create one, how to add it correctly, and a mix-up that causes more “my signature disappeared” complaints than anything else: desktop and mobile Gmail signatures are two separate settings.

How to Create a Gmail Signature
Building a Gmail signature takes just a few steps.
- Go to a Gmail email signature generator, like our free Email Signature Generator.
- Enter your name, job title, company, and contact details.
- Choose a layout and accent color.
- Copy the generated signature.
Once it’s copied, you’re ready to add it to Gmail itself.
How to Add Your Signature to Gmail (Desktop)
- Open Gmail and click the gear icon in the top right, then See all settings.
- Stay on the General tab and scroll down to the Signature section.
- Click Create new, give it a name, and paste your signature into the box.
- Under Signature defaults, choose whether it should appear on new emails, replies, or both.
- Scroll to the bottom and click Save Changes.
Gmail allows up to 10,000 characters in a signature, which is far more than any normal signature needs.
Why Your Signature Isn’t Showing Up on Mobile
This is the part that trips up more people than anything else about Gmail signatures, and it’s confirmed directly by Google’s own support documentation.
Gmail treats your desktop signature and your mobile app signature as two completely separate settings. Creating a signature in Gmail on your computer does not automatically make it appear in the Gmail app on your phone. You have to set it up a second time, specifically inside the mobile app.
To fix this on Android or iPhone:
- Open the Gmail app.
- Tap the menu icon (three lines) in the top left.
- Scroll down and tap Settings.
- Select your Google account.
- Tap Mobile Signature.
- Paste or type your signature, then save.
If you skip this step, Gmail simply uses no signature at all on emails sent from your phone, which is usually when people assume their signature “disappeared.”
Gmail Signature Example
Here’s a clean, standard layout that works well across most Gmail inboxes:

Adding a small logo or a single social icon works fine too, as long as the file size stays small. Large images can slow down how the signature loads inside Gmail’s editor and may get stripped out entirely on some email clients your recipients use.

Personal Gmail vs. Google Workspace Signatures
If you’re using Gmail through a business Google Workspace account rather than a personal Gmail address, your organization’s admin can set a mandatory signature or footer that applies across the entire company. This is managed separately from the personal signature settings covered above, through the Google Workspace Admin console rather than individual Gmail settings.
For most freelancers, small business owners, and individual employees, the standard signature steps in this guide are all you need. The Workspace-wide option only matters if you’re managing signatures across an entire team from one central place.
Common Formatting Problems
Complex signatures can break in Gmail’s editor. Gmail’s signature box only reliably supports basic HTML: bold, italics, links, and images. A signature built with heavy inline styling or unusual formatting from another tool can render incorrectly, or fail to save properly.
Images don’t resize inside Gmail. Gmail has no built-in image resizing tool. If your logo or headshot looks too large, resize it in an image editor first, then upload the correctly sized version.
Pasted signatures can carry hidden formatting. Copying text from a Word document or another email into Gmail’s editor sometimes brings along formatting that clashes with Gmail’s own styles. If your signature looks off after pasting, try clearing formatting first, then reapplying it inside Gmail directly.
Where Your Signature Appears in a Reply Thread
By default, Gmail places your signature at the very bottom of a reply or forwarded thread, not right under your latest message. On a long email chain, this can make the signature easy to miss, since it’s buried below all the previous messages. If you want it directly under your reply instead, you can manually move it while composing.
What to Include in a Gmail Signature
A clean, professional signature typically includes:
- Full name
- Job title
- Company name
- Phone number
- Website link
- One or two relevant social links
Keep it short. A signature with too many links, images, or banners often looks cluttered on mobile screens, where most people actually read their email.
Quick Troubleshooting Checklist
If your Gmail signature isn’t behaving the way you expect, run through these before assuming something’s broken:
- Not showing on mobile? Set it separately inside the Gmail app, not just on desktop.
- Not appearing on new emails? Check your Signature defaults setting under General.
- Looks broken after pasting? Clear formatting first, then reapply basic styling inside Gmail.
- Image too big or blurry? Resize it externally before uploading, since Gmail won’t resize it for you.
- Missing from a specific address? If you send from multiple addresses, confirm you’ve set a signature for that particular one.
Most Gmail signature problems trace back to one of these five issues, and each one takes under a minute to fix once you know where to look.
FAQs
How do I add a signature in Gmail?
Go to Settings, then General, then the Signature section. Click Create new, paste or type your signature, and save. This only sets your desktop signature; the Gmail mobile app needs its own separate setup.
Why isn’t my Gmail signature showing on my phone?
Gmail uses a separate signature setting for its mobile app. You need to add your signature again inside the Gmail app itself, under Settings, then Mobile Signature.
How many characters can a Gmail signature have?
Up to 10,000 characters, which is more than enough for any standard professional signature.
Can I use HTML in my Gmail signature?
Yes, but Gmail’s editor only reliably supports basic HTML like bold, italics, links, and images. Signatures with complex styling from other tools can render incorrectly.
Can I create a Gmail signature for free?
Yes. A free email signature generator, including ours, lets you build a formatted Gmail signature at no cost, ready to copy and paste into Gmail’s settings.
Can I have different signatures for different Gmail accounts?
Yes. If you send mail from multiple addresses through Gmail’s “Send mail as” feature, you can set a separate signature for each one from the same Signature settings page.
Does my Gmail signature automatically appear when I reply to an email?
Only if you selected that option under Signature defaults when setting it up. You can choose to show your signature on new emails only, on replies and forwards only, or both.
