I don't find the interface easy to use. there are far too many steps to get to the end result. I'm in the process of handing over my current position and am writing notes for my colleague to show them how to use Message Media. I have counted 10 steps to get to the final screen which I think is ridiculous. And having to print out every screen as I cant remember myself which button to click on next. I also feel preparing the Excel spreadsheet is another time consuming exercise, ie, deleting all unnecessary fields , then changing the word "Mb Phone" to "Mobile", then copying and pasting those fields into another document (otherwise it wont upload). All too complicated. I prefer SMS through my regular email with two simple steps, but unfortunately am unable to use it due to spam . I had to call customer service which were helpful a couple of times to guide me through all the steps as at first I found it overwhelming, now its just very time consuming and frustrating to remember each time I use it. Sorry, not a fan.
