Whether you're an HTML whiz or have no idea where to begin, we have you covered. This wikiHow teaches you how to create an HTML email signature that you can use in Gmail.

Things You Should Know

If you don’t want to make your HTML signature from scratch, use a signature generator to start with a template.

Building a Signature

1
Decide whether to use a signature generator. If you're not skilled with HTML and/or want to customize a template instead of starting from scratch, an HTML signature generator is best. A generator makes it so you don't have to write the code yourself or scour the web for images and icons.
- Although most HTML signature generators cost money, HubSpot's signature generator is free. You can start with one of 6 templates and add your own info and images.
- For professional templates and more advanced features, try a paid signature generator like MySignature,or Newoldstamp, or Si.gnatu.re.
- If you do know HTML, compose your signature in a WYSIWYG editor like this online editor. You won't be able to just copy the raw HTML code and paste it into Gmail—you'll actually have to copy and paste the signature itself, which will automatically embed any images you added in the editor.
2
Download icons or images for your signature. If you aren't using a signature generator's built-in icons, you'll want to find royalty-free icons to use. For example, if you want to include social media links in your signature, you'll want to use icons instead of long ugly links.
- Check out Uxwing and Flaticon for thousands of free icons.
- When downloading an icon, save it in the PNG format for the best quality-to-size ratio and compatibility.

Reduce the size of your icons and other images. You can skip this if you're not adding your own icons. The standard email signature width is 650 pixels, but you can make it even thinner than that to ensure it will look right in all email clients.^{[1]

- You may have to play around with the sizing a bit until you find one that works with your design, but start with 50 to 100 pixels per icon.
- Some popular online image resizers are OnlinePNG Tools and Adobe's free resizer.

Design your signature. If you're using a signature builder, edit the template as described by the editor. If you're using an HTML editor, just write the HTML by hand, or use the style tools built into the WYSIWYG portion of the editor to lay out your signature. Some important things to keep in mind if you're using an HTML editor:
- Stick to 650 px width or less.
- Avoid using bullet points, as they may render strangely on different email clients.
- Using too many (or too large) images can obscure the text.
5
Generate your signature. If you're using HubSpot's signature generator, click Create signature. If you're coding in HTML by hand, switch to the WYSIWYG version of your editor to view the signature, or open it in a web browser.
6
Copy the signature. Be sure not to copy the HTML—you need to copy the signature visually. Click the Copy signature button in most signature builders, or use the mouse to highlight the signature and press Control + C (PC) or Command + C (Mac) to copy it. Once it's copied, you can paste it into your Gmail signature.

Adding the Signature

Go to https://www.gmail.com in a new browser tab. If you're not already signed in, sign in now.

Edit the signature. Now that you've designed the HTML version of the signature, you can do edits in Gmail's regular signature editor. Double-check all of the information for typos so it doesn't look unprofessional.

Set your signature. Now that you've added your signature, you'll want to choose when it should be appended to your emails. To append it to all emails, select the name of the signature from the "FOR NEW EMAILS USE" menu.
