This weird interaction is what I picture in my head every time I see someone include their email address in their email signature. How could that possibly be good email etiquette? In fact, 39% of people do this!
It turns out including an email in an email signature (sounds so wrong everytime I say it) is one of the 15 email signature mistakes we all make. The following presentation uncovers the rest:
1. Including your email address
This is the ultimate insult. You might as well say:
p.s. Just in case you’re totally oblivious to how email works, here is my email address at the bottom of my email from the email address you just received this email from.
Thanks, Captain Redundancy
2. Including a fax number
No, most people aren’t still living in 1994 and sending faxes. Or 1894 and riding horses to work.
3. Leaving "Sent from my iPhone" as the default signature
This also means:
Yes, I'm capable of grammar and spell checking. But I'm on my iPhone, so that means rules don't apply to me. Oh yeah and if I call you jerk instead of Jack, yes, that's my AutoCorrect. Deal with it!
Instead, why don't you just proofread before you send like you would on desktop? Not that hard.
4. Not promoting your website in a unique way
Noah Kagan, CEO at Sumo, uses a unique email signature that has driven thousands of downloads for his free product.
5. Listing every social media profile
Newsflash: No one is going to click every single social media icon. Instead, focus only on the accounts that matter most to growing your business or building your personal brand.
6. Using a large image that takes forever to load
If you use a 15 megabyte picture in your email signature, your recipient will reminisce to their dial-up internet days because your email is loading so dang slow.
7. Copying and pasting an image into your signature
By pasting an image into your signature, it will appear as an attachment, versus embedded in the signature.
8. Not including your phone number
There are two professional ways to get in touch with people:
They obviously have the first. Don’t forget the second.
9. Forgetting an international prefix if you have international clients
If you work with international folks, it’s helpful to include the prefix for your country’s code. For example, the United States code is +1. The code for Brazil is +55.
10. Using a corny quote
Keep the inspirational quotes on Pinterest and Tumblr, not in email signatures.
11. Colored, large, or weird fonts
Keep a clean, black font your signature. Preferably in a font that is NOT Comic Sans or something else that hurts the eyes.
12. Sloppily inserting the full hyperlink into your website or social media accounts
Using the Gmail keyboard shortcut, use "Command + K" to insert a link. That shortcut is pretty universal so it should work for all other email clients as well.
13. Including every service you provide
Just because you offer 57 different marketing services, doesn't mean you need to include all of them in your email signature.
14. Using an entire image as your signature
Including an image, such as your face or a logo, is risky because it may not work. But having your entire signature as an image is just foolish. It just won't work. Use our free email signature generator to create an easy-to-use signature now.
15. Not testing your signature in multiple email clients
Just because it works in Gmail, doesn’t mean it works in Outlook. Test your signature in all of them.
