Your email signature is a useful tool for branding and making your operation look more professional. A well-designed signature provides essential contact information, can drive traffic to your portfolio or social profiles, and makes a positive impression on recipients, whether they’re partners or potential clients.

If you’re a Gmail user, this step-by-step guide will show you how to create and edit your Gmail signature on both desktop and mobile.

How to Change Your Signature on Desktop

Changing your signature on a desktop computer gives you the most control over formatting and design. Here’s what to do:

  1. Open Gmail and access settings: First, log in to your Gmail account. In the top-right corner of the page, click the Gear icon to open the quick Settings menu. From the dropdown, click See all settings to access the full settings page.
  2. Open the signature section: Go to the General tab, and then scroll down the page until you find the “Signature” section.
  3. Create or edit your signature: You can either create a brand new signature by clicking the Create new button or edit an existing one.
  4. Add your information: Use the text editor to design your signature. A professional signature should include your full name and professional title, company name and website, key contact information, and a link to your LinkedIn profile or professional portfolio. You can use the formatting toolbar to adjust the font, size, and color, insert images like a company logo, and more.
  5. Set your signature defaults: Below the editor, you’ll see a section to set your signature defaults. Use the dropdown menus to select your new signature for “For new emails use” and “On reply/forward use.” This will ensure your signature automatically adds to your emails so you don’t have to do it manually every time.

Finally, scroll all the way to the bottom of the page and click the Save Changes button. If you forget this step, all your work will be lost. The whole process should take just a minute or two.

How to Change Your Signature on the Gmail Mobile App

Changing your signature on the Gmail mobile app is more streamlined, but it offers a little less functionality. Plus, it’s important to remember that any signature you add on the mobile app is separate from the desktop version.

Here’s how to set it up:

  1. Open the app and access settings: Open the Gmail app on your mobile device and tap the three horizontal lines in the top-left corner. Scroll down the menu and tap Settings.
  2. Select your account: If you have multiple Google accounts, tap the one you want to edit.
  3. Access the mobile signature section: On iOS, tap Signature settings. On Android, scroll down and tap Mobile Signature.
  4. Edit and save: Enter or edit your signature directly in the text field. The mobile app’s editor has fewer formatting options than the desktop version, so keep it simple and concise.

When you’re ready, your changes will be saved automatically or after you tap “OK.”

Best Practices for a Professional Signature

Your signature can be a great way to convey important information and legitimize you and your business. Here are some tips to make it the best it can be:

  • Keep it concise: A signature should be easy to read and understand. Avoid overly long quotes, legal disclaimers, or excessive information.
  • Use high-quality images: If you’re including a company logo or an image, make sure it’s a small file size and good quality to avoid slowing down email loading.
  • Think about your links: If you use links, make sure you use clear, descriptive text for them rather than pasting URLs. Instead of pasting “https://cobanker.com/” use “Visit Cobanker”.
  • Stay consistent: While your mobile and desktop signatures are separate, try to keep the key information consistent across both.
  • Avoid clutter: Don’t use overly long quotes or disclaimers, large image files that slow down email loading times, or so many social media icons that clutter the signature.

These best practices will help you set up a strong signature that prominently represents you and your brand.

FAQs

Yes, on the desktop version of Gmail, you can create multiple signatures and assign them to different situations (one for new emails, another for replies) or switch between them manually when composing a message. You can only have one on the mobile app.

You can only add images to your signature on the desktop version of Gmail. In the Signature editor, click the “Insert Image” icon, and you can upload a file or paste a URL. For best results, use an image that has been resized to a small, web-friendly size (such as 100×100 pixels).

If your signature isn’t appearing on replies or forwards, it’s likely because you haven’t set the default for that action. On the desktop, go to your Gmail settings, scroll to the Signature section, and make sure you’ve selected your signature from the “On reply/forward use” dropdown menu.
