How to create a professional Gmail signature 

If want an email signature design that uses more than plain text, a bit more thought is needed.

Why you should add a logo to your Gmail signature

A logo is a crucial visual representation of your brand. Adding it to your Gmail signature can leave a lasting impression on recipients, enhancing brand awareness and recognition. A professional logo in your email signature boosts credibility, making your emails look more official and trustworthy.

Including a logo in your Gmail signature supports your marketing efforts. Each email sent with a visible logo increases the likelihood of recipients remembering and recognizing your brand. This simple addition can make your emails stand out, promoting your brand identity effectively.

Tips for using logos in Gmail signatures

  • Keep it simple: A cluttered Gmail signature with your logo can distract from its impact. Use one or two colors and limit text to focus on the logo.

  • Make it clickable: Enhance the effectiveness of logos in Gmail signatures by adding a hyperlink. Highlight the logo in the signature editor, click the link icon, and attach a URL to drive traffic to your site.

  • Follow branding guidelines: Ensure logos in Gmail signatures align with your brand's visual identity, using correct colors and fonts for consistency and reinforcement of your brand image.

  • Update regularly: Whenever your logo changes, update it in your Gmail signature to maintain consistency with your current branding across all email communications.

How to change your signature on Gmail

Fortunately, knowing how to change Gmail signatures is much easier than creating a brand new one. Here’s a step-by-step guide on how to change Gmail signatures:

  1. Open up Gmail.

  2. In the top right, select "Settings," then click "See all settings."

  3. Near the bottom of the page, you'll find the section on changing Gmail signatures. In this section, add the text of your signature to the box.

  4. Feel free to style your signature using formatting options or by adding images.

  5. After all that is done, click on "Save changes."

Learning how to change Gmail signatures is straightforward, but having to update it for every promotion or season can become tedious quickly.

Manually changing Gmail signatures takes time, but it offers flexibility. You can change the font, font size, and color, add hyperlinks, and even include clickable phone numbers. Knowing how to change Gmail signatures effectively can make your email communication more dynamic and personalized.

How to add an HTML signature to Gmail  

To add an HTML signature to Gmail, follow these steps:

  1. First, design your HTML signature using a professional email signature generator tool or by coding it yourself.

  2. Save your HTML file and open it in a web browser.

  3. Right-click on the signature and select "Select All".

  4. Right-click again and select "Copy" to copy the HTML code.

  5. Open your Gmail account and click on the gear icon at the top right corner of the screen.

  6. Select "Settings" from the drop-down menu.

  7. Scroll down to the "Signature" section.

  8. Click on the "Create new" button.

  9. In the text box, click on the "Insert HTML" button in the toolbar.

  10. Paste your HTML code into the popup window and click "Ok".

  11. Your HTML signature will now appear in your Gmail signature editor.

  12. If necessary, use the toolbar to make any formatting changes.

  13. Click on the "Save Changes" button at the bottom of the page to save your HTML signature to Gmail.

What specific font size should you pick for your Gmail signature?

To maintain readability and professionalism, it's recommended to use a font size between 10 and 12 points for your Gmail signature. While smaller sizes may be stylish, they can be hard to read, especially on mobile devices. Larger fonts might look unprofessional. Consider using 12 points for your name and 10-11 points for additional details.

How to set auto signatures in Gmail

To set auto signatures, navigate to Gmail settings, select the "Signature" section, and choose your default signature for new emails and replies/forwards.

Gmail allows you to set different signatures for multiple accounts. Make sure "Insert signature before quoted text" is checked if you want it added to replies.

Troubleshooting common Gmail signature issues 

  • Logo not appearing properly: If your logo is not displaying correctly in your signature, try resizing it and making sure it is saved as a PNG file.

  • Signature not showing up on replies or forwards: By default, Gmail only adds signatures to new emails. To include your signature in replies and forwards, go to the "General" tab of your settings and check the box next to "Insert this signature before quoted text in replies and removes from forwards."

  • Text formatting issues: If you experience any issues with font or text alignment in your signature, make sure that you are using the correct font type and size. You can also try copying and pasting the text from a different source, such as a plain text editor.

  • Mobile version of signature looks different: Due to varying screen sizes and email client compatibility, your mobile version of the signature may look slightly different. Test it on different devices and make adjustments as needed.

Managing signatures in Gmail companywide 

The process for how to change Gmail signatures works well for an individual user or a personal account. If you want everyone in your company to use the same default Gmail signature, you’re going to run into trouble.  

Asking all users to create and manage the same signature template will lead to huge inconsistencies. If you have an IT department, they could manually go to each person’s desk and do the necessary signature updates. But that will be a tedious process. You also won’t be able to stop end users from modifying and changing their signature in Gmail directly. 

In other words, you won’t have any control if you let your users manage their own signatures in Gmail.
