I can't speak highly enough of SMS Broadcast UK! I help run a kids' football club and as a Manager of one of the teams I need to quickly contact parents in the event of a match cancellation, change of venue, etc. It was driving me crazy doing this all manually on my phone. With this service, I load my contacts once and then can send personalised text messages to the relevant people from my last in literally a matter of seconds. Delivery is instant and faultless. Can't recommend this highly enough - and as a company director I can also see the huge potential this would have for businesses wanting to do more with SMS for customer contact, outreach, etc.
