Is there a common file format that all email clients understand? I am in the process of assigning email accounts for members of my local community organisation http://northpinecid.co.za/. Because it is volunteer-based, most of them will be accessing their company* email from private devices/computers. This means that there will be a number of different email clients in use. I want to ensure that a uniform company branding style appears in the email signature of each member. How can I do this across various email clients?
