even if it's not your actual signature? - Zee.

The cutesiness is offset by having yet another graphic embedded in email, which IMO is better off the more it's just text. - Andrew C

but what would tend to happen is people using plain text email clients would just see the text replacement in this case no? - Zee.

Not a big fan, myself. Not especially secure (if it's your actual signature), adds an extra attachment, and we all know how unreliably e-mail clients tend to show images. - Curtiss Grymala

I'm not a huge fan of graphics or images in email signatures as it means getting an attachment from them on every email. I stick with plain text. - Mike Bracco

I guess it depends on what type of emails it is used in and to whom it is sent. I'm sure a good percentage of hardcore internet users would find it annoying and/or tacky and/or inefficient. Grandma would probably love it, but in business/transactional type of stuff, it may have an adverse effect. - 1001 noisy cameras

Naff. Same for company logos. At some point in the thread the mail goes to a plain text-only client and then all the graphics become attachments that are out-of-context. If your company strapline doesn't work as text without graphics or a specific font, it doesn't work. - sjjh
