6 Things To Avoid In An Email Signature

Email signatures are a brilliant way to forge links between your business and its clients. Signatures can include everything from social media links to legal disclaimers and, while the possibilities are varied, they certainly aren’t endless. Some additions to the signature can undermine both your business and its marketing message.

#1 Lots of contact details

Contact details are (obviously) an important part of any email signature. They can direct a customer’s future interactions with the company, and having all the contact details in the same place cuts down on any confusion. Including too many details, however, has the opposite effect. Email recipients won’t know which details to use, where to look, and might even reach out to the wrong person. That leads to further unnecessary and time-wasting email communication. 

#2 Custom fonts

The problem with custom fonts is twofold. For a start, most look unprofessional. Customers are used to seeing traditional fonts like Times New Roman, Arial, or one of the other popular styles. Suddenly filling your signature with new fonts gives your company an amateurish look. Worse still, many custom fonts simply won’t be supported by the system at the other end, meaning that they’ll leave a blank space in your signature.

#3 Bullet points

Bullet points can seem like a good idea. They’re an effective way to space information, and they’re easy to follow, but they don’t work quite that way in emails. Formatting issues can skew bullet points, put in random spaces, strange indentations, and make your list appear unwieldy and chaotic. Generally speaking, you should keep signature formatting as simple as possible or use a specialized generator like rocketseed.com to ensure that everything is laid out correctly.

#4 Animated gifs

Animated gifs might seem quirky and fun (and you might buzz across the office email from time to time), but there’s no place for them in a well-put-together email signature. Animated gifs look unprofessional, but they have a more fundamental flaw. Since they can take up quite a large file size, they’ll be slow to send, slow to load, and in some cases simply won’t load at all, leaving a blank space in your signature. They’re often poorly received if they do load, too.

#5 Videos

It can be tempting to put a company video in your signature, but it’s never a good idea. Most email clients don’t support video (or at the very least they won’t make the video autoplay as you hope), and videos boost your email’s size quite considerably. Sending will be slower, and in most cases, the video simply won’t load, leaving an empty space.


Another seemingly good idea, quotes in reality add nothing more than unnecessary clutter. Everybody reacts to quotes differently, so even if you found the words inspiring, there’s no guarantee that somebody else will. Email signatures should be as succinct as possible, and most people will simply skip over a quote since it doesn’t add much value to the email.
