I have a friend who runs a business who distributes emails to a few thousand customers at a time. They want to be able to send out emails that looks more professional than just plain text. I think they need to be using HTML to make the email but is there an easier way to do this because they are not very tech savvy. They are not using "Mail" to send out the emails since it is a mass email, they have an email server and a program that they use to send out the emails but just don't know how to make them look better. Additional information : They don't want to use a service, they do not want their email list exposed to third parties so using one of the email services is out of the question. Any suggestions?
