What to Include in an Email Signature

Before we get into the how, the what needs to be addressed. You might be so inclined to add a ton of information into your email signature. Back in the early 2000s it became popular to place animated graphics in email signatures. This trend was met with much resistance for the same reason people have advocated for short signatures all along:

It takes up precious bandwidth.It adds considerable size to the emails.

Consider this: You send an email with a signature that includes text, HTML, and a large animated image. The person you sent that to replies with a similar signature. You then reply on the same thread, and that keeps going back and forth for some time. Imagine how large that email will have become, with those signatures repeated over and over. Because it’s more efficient you want to keep your signature to a minimum. In fact, the old standard was that an email signature should not go beyond three lines. That same idea holds true today, so keep that in mind when designing and composing your email signature.

How to Add a Text Signature in Thunderbird

Adding a well-designed signature to Thunderbird is simple. Just follow these steps:

How to Add an HTML Email Signature in Thunderbird

A text-based signature is great, unless you want to make it easy for recipients of your email to easily clink on a link that will take them to your (or your company’s) website. In that case, you need to use an HTML signature. Let’s say you want to create a signature that includes a link to Lifewire. Here’s how you add such a signature: Now, when you send an email from that account, it will include a signature that contains a clickable link to the Lifewire site or whatever site you wanted to add to your signature.

How to Add an Image as your Signature

If you want to add an image as your signature, the process is also quite simple: Going forward, whenever you send an email it will include the image you selected as your signature. Do make sure to keep the images on the small size. A good rule of thumb is to keep the file size below 50kb so it doesn’t require a large amount of time to load.

Add Both an Image and HTML to Your Thunderbird Signature

This is where it gets tricky (and helps to know a bit about HTML). Instead of teaching you how to use HTML, we’ll illustrate a signature file that contains some text, an image, and a link to Lifewire.com. That’s really all there is to adding an email signature to Thunderbird. A few clicks and some basic HTML code can help you carefully craft a signature will serve you well for whatever purpose you choose.
