Signature Image Space

I have created a signature for the bottom of my email address used for my business.
The signature has my name, address and other details on it and I have put the company logo and name beneath.

When I created and edit the signature there was/is one empty line below the email/web address and the company logo image, but when I send the email the name and logo are much lower with a large space in between. Please see attached screenshot as its a little hard to explain what I mean.

Does anyone have any ideas why this is happening or how to not have a space?

Hello Mark,
Thank you for provided screenshot.
Does the signature appear like this when composed and sent?
Have you by any chance pasted it from some text editor?
Also you can send me a message as .eml file to [email protected] so I can take a look at it.

Edit your signature and use [shift] [return] instead of a return. In html, a return is a new paragraph, shift-return is a line feed. That work?
