How can the amount of data transfer used by reduced?
Firstly try to avoid sending large attachments out on your email list. It is much more efficient to upload the attachment to a webpage and then send a link out. An upper limit can be set for the size of emails under ‘List Settings’ in the members’ area. If you want to reduce your use even further, then we can strip all the HTML formatting from your list messages, which will reduce the size by several fold.
