Hi all. I have created a business signature for the emails and when sending looks good. However when opening a test email it shows with 2 images (2 logos)  instead of 1 as it shows when sending. Also it looks fine when opening said email in an internet browser like hotmail but if opening on phone/mac etc it shows with 2 images. Has anyone encountered this before and able to help? Thank you
