I really like that it's very easy, fast & cheap! It has been so simple to use in my day-to-day work as an Account Manager at a Marketing Agency - sending out marketing emails or even just regular communication between colleagues. The only thing which could be improved would be if there was more flexibility around formatting of numbers etc but this isn't too much hassle once you've used sheet2sms for a while. We have saved money by using sheets2sm rather than paying per number each month through
