Before You Start: What You Can Add to a Gmail Signature

A good email signature for Gmail should include your name, job title, company, phone number, website, LinkedIn profile, company logo, and a call to action. Keep it short so it looks nice on mobile devices.

How to Add a Signature in Gmail on Desktop

Crafting an impressive email signature is straightforward with specialized tools like Newoldstamp.

The Gmail signature editor offers only basic options. Yet if you want to do it all yourself, I will walk you through the steps to create a professional email signature in Gmail in no time.

Don't miss out on the opportunity to enhance your email signature – whether you prefer a hands-on approach or the simplicity of a signature generator, we've got you covered.

Step 1. Open Gmail Settings 

Go to your Gmail on desktop. Click the gear icon in the top right, then choose See all settings. You’ll be in the General tab.

Step 2. Go to the Signature Section

Scroll down to the Signature area. This is where you create and manage a signature for your Gmail account.

Step 3. Create a New Signature

Click Create new, give it a name, and enter the text you want to appear. Creating multiple signatures lets you switch between them using the pen icon while composing messages.

Step 4. Add Your Contact Details

Remember not to turn it into a laundry list. Include essential details like your name, position, company website, and phone number. Keep it concise and professional.

Consider using this standard Gmail signature format:

[Your Name]
[Your Position] at [Your Company]
_________________________________
Website: [Your Website URL]
Mobile: [Your Phone Number]
Address: [Your Address]

Note: Explore our free email signature generator for a simple yet visually appealing email signature.

Step 6. Add Links to Your Gmail Signature

Consider adding a link to drive people to your website.

Another nice trick for getting under your subscriber's skin is by adding your photo. It will prove that there's a real person behind the email and will maybe make it a bit harder for them to say no to your requests.
