I help run an allotment association with 83 members. We regularly need to contact the membership, sometimes on an emergency basis when there have been break-ins onsite for instance. We also need to contact them on other more mundane matters such as notifying them of meetings or availability of stock which we sell. Prior to discovering and using Voodoo the only method we had to do this was by notice boards on site, which is a bit hit and miss, or by post. Postal charges are prohibitive as well as the cost of stationary and printing it was a method we only ever used rarely because of the limited funds we have. Even at around 3p per message the costs of Voodoo messaging is negligible in comparison. Additionally, it's easy to keep the database of contacts up to date using their easy to use online dashboard. Voodoo has been a brilliant addition to our ability to communicate with our membership and has been a huge plus to the management team and membership alike. We are only a small organisation and bearing in mind the mass ability of Voodoo to send SMS we feel perfectly at home in the limited way in which we use it. A brilliant system I would recommend to any size of organisation.
