I recently sent about 5000 texts to contacts on a database advertising a new app through SMS Broadcast. The process of writing messages, adding numbers and sending was relatively simple. And you are able to use a personalised business name to send from. However - the next part was slightly un-nerving. After I sent the messages, it said 'estimated delivery 2 minutes'. I left it to send the message and went back to it about 15 minutes later, it still said 2 minutes delivery time left. I assumed it had sent them all and went to refresh the page. I had about 1000 more credits left than what I anticipated, so I assumed that some of them hadn't sent. When actually, the 1000 was from numbers that either didn't exist or weren't delivered properly. I was not told this which confused me. Something to think about in the future. The reporting could do with looking at too. I can only see How many were delivered, how many sent, and how many undelivered. No stats in how many opened the text or when. Thanks
