Don’t use images in your email signature. Ever.

Maybe you think a logo or other image in your email signature looks cool and professional. Maybe it does. But I assure you, broken images, incorrect file counts, lost attachments and general confusion does not.

Here’s why you should never ever use an image in your email signature.

Images may not be displayed properly, depending on the recipients email application or its settings, especially when an email gets forwarded.  A broken image next to your name just looks plain unprofessional.

The image is a file attachment, so all your emails will be marked as having attachments. It makes it harder to notice when you have manually attached a file. The total count of attached files will be incorrect since it adds the image(s) in your signature. Also it will be impossible to sort or filter your messages on attachments.
Messages in HTML format is a way to make the image not be categorized as an attachment, but there is no guarantee it will work depending on settings, and images in HTML messages are more likely to be blocked by the application.

You don’t want to be the reason for this conversation:

-Did you get my email?
-Which one?
-The one with the files.
-Er, they all have attached files as far as I can see.
-This one has eight files in it.
-I have no email from you with eight files. The closest is nine.
-That’s wrong. I sent you eight.
