Step-by-Step Guide on How to Add a Signature in Gmail
A polished Gmail signature does more than look good—it builds trust, boosts engagement, and promotes your brand with every email. This step-by-step guide shows you how to set it up right, on desktop and mobile.
So, you’ve mastered the art of crafting emails. What about how you end your emails? If you’re not adding a signature to Gmail, you’re missing out—A LOT.
A Gmail auto signature is a block added to every outgoing email’s end. When designed well, it makes your emails appear more professional, polished, and a little bit cooler. This is a valuable space to grab your recipient’s attention, promote your brand, and trigger engagement. Designing an effective Gmail signature line requires balancing visual appeal with conciseness. But it’s not hard to do. Here’s a step-by-step guide on how to add signatures in Gmail on the web and mobile app:
Key Takeaways
- A well-designed, visually appealing email signature increases reading rate and engagement.
- Gmail email signatures use colors, logos, social media icons, and links to balance conciseness and visual appeal.
- You can use a tool like Wisestamp to create multiple Gmail signatures automatically.
- Common Gmail signature problems include missing images, extra characters in the signature, and signatures not appearing in emails.
Should I Add an Email Signature to My Gmail?
Smaller, often-overlooked spaces like the Gmail signature block can offer immense benefits without much extra effort. Some of these include:
1. Increase your email reading rate
Most readers hurriedly scan emails without processing the intended message correctly. To increase your email reading rate, find ways to capture your recipients’ attention and make them slow down.
Adding an attractive and informative email signature, like a colorful banner, can grab their attention and make them more likely to engage with your message.
2. Make a professional first impression
An email with a signature portrays you as someone who pays attention to the details. It creates an impression that you are organized and reliable.
3. It’s a mini-marketing tool for your content and products
Gmail signature settings allow you to include links and formatted buttons. You can also add engaging CTAs like “Watch our latest webinar” or “Request a free demo.”
4. It’s a passive channel to grow your social media followers
Including your social media icons in your Gmail email signature makes it easy for them to jump directly to your pages across different platforms, engage with your content, and stay updated.
How to Create and Add an Email Signature in Gmail
Adding a signature in Gmail can be done in just a few steps, whether on the web or phone app.
How to add a signature to Gmail on the web (Mac and PC)
Gmail does not have a desktop app for both PC and Mac operating systems. The only way to access your account is via the Gmail web version, which works similarly on both systems.
Step 1 
Open Gmail Settings
In the top right corner of your screen, click on the gear icon and then click “See all settings” in the Quick settings panel.
Step 2 
Navigate to the signature section
In the settings panel, scroll down to get to the Signature tab. Click on the “Create New” button to add a Gmail signature.
Step 3 
Add your signature details
Create your signature in the text box to the right of your signature name. Ensure you include your full name, job title, company name, and contact information.
Step 4 
Edit your Gmail signature
The next step is using the rich text editor to make your signature look neat and professional.
Here’s how to edit signatures in Gmail:
Change font size:
- Select the signature text you would like to edit
- Click on the tT icon at the left of the toolbar > choose the text size you’d like to use (Small, Normal, Large, or Huge)
Change text color:
- Click on the A icon at the right of the signature editor’s toolbar
- Pick the text color you’d like to use from the right-side color pallet
Change signature font:
- Click where it says “Sans serif” on the left side of the editor’s toolbar
- Choose the font you’d like to use for your signature (these are all email-safe fonts)
Step 5 
Set auto Gmail signatures and save
Just below the signature editor, you’ll see additional settings that let you tell Gmail which signature to set as your auto signature for New and Reply/Forward messages. Lastly, scroll down to the bottom page and click “Save changes.”
How to create a signature in Gmail mobile app
The email signature you create on Gmail’s web version is not applied to the emails you send from the phone. The only exception is if you are using a platform like WiseStamp, which applies your signatures to all your devices automatically.
If you mostly compose emails using your phone, adding a Gmail digital signature becomes necessary.
Setting up signatures in Gmail mobile app (Android)
Step 1
Launch the Gmail app on your Android phone
Step 2
Navigate to Gmail signature settings
Click the three-line icon at the top-left corner of your phone’s screen. Scroll down and tap “Settings.”
Step 3
Select your email address
If you have multiple email addresses attached to your phone, you’ll be prompted to choose the account you wish to make changes to from a list.
Step 4
Navigate to mobile signature and design your signature
Scroll down to the Mobile signature section. Tap on it and type your signature. Note that the Gmail app version only supports plain text signatures. Click “OK” when you’re done to save your signature.
How to add a signature on the Gmail app (iPhone)
Gmail signature settings look a little different on Android and iPhone, and the setup steps vary slightly too. Here’s how to set up a Gmail signature on iPhone:
Step 1
Navigate to signature settings on the Gmail app
Open the Gmail app on your iPhone and click on the hamburger icon at the top-left corner of the screen. Scroll down and tap on signature settings.
Step 2
Type your signature
In the window that opens, enable mobile signature. Type your signature in the text box that comes up. Tap Done at the top-right corner of the screen to save your signature.
Step 3
Test your signature
That’s how to insert a signature in Gmail on an iPhone. Try composing a new email. Your new signature should appear in the body of your email.
Tips on how to avoid and resolve technical issues when adding signatures to Gmail
There are several technical issues to beware of when learning how to add an email signature in Gmail:
- Signature not appearing on new emails
- Images missing in the signature
- Extra characters in the signature
Signature not appearing on new emails
In most cases, this happens when you have selected “No signature” as your default signature. Navigate to Gmail signature settings > signature defaults and double-check that you have selected the correct signature as your default. Remember to click “Save changes” at the bottom of the page.
Images missing in the signature
A common reason for images not appearing in email signatures is if they are hosted on a private server. To fix this issue, use a working image URL or upload an image from your device.
Keep in mind that your images may not appear if they are too large. Keep image file sizes under 1MB to minimize load times.
Extra characters in the signature
Extra characters in email signatures often occur when some Gmail versions don’t support a given formatting option like bold or italics. To solve this problem, navigate to your Gmail’s signature section and highlight your signature. Click “Remove formatting.”
