We have had an overwhelming response since launching Sendible a month ago. Almost 5000 users have registered and we've had around 30 000 messages sent.
Unfortunately, due to this overwhelming response, we have had to make the SMS service a paid-for-only service until we can get more advertisers on board. We are however offering AMAZING rates on SMS messages.
You can get 10 credits for $1 and obviously the more you buy, the cheaper it becomes.
Of course, We do still provide 5 free SMS reminders per month!
