Twitter for Customer Support
I use Rackspace to host all our web servers for ourselves and our customers. I was playing with their iPad app one afternoon and found a problem. It is not a mission critical error, so I wrote a tweet to them, something like "Hey @rackspace your iPad app is crashing". Within minutes they tweeted me back, asking me to email them with specifics. Soon they both emailed and tweeted me back with a solution. I was happy. Then to top it off they offer to send me a t-shirt! Honestly I would have been very happy just with the speedy response via twitter.
Twitter for Pre Sale Support
I was looking to buy a small messenger bag from Rickshaw Bags as a gift. I wanted to know if a Kindle Touch would fit in their mini zero bag. The dimensions given on their websites are too close. So I tweeted a question to @rickshawbags. Within minutes they answered, via twitter. I placed the order. During the check out process they asked me for my twitter handle.
Twitter for Post Sales Support
This evening, Rickshaw Bags tweeted out to me, with a little custom poem, a pictures of the bags that I ordered, before they are handed off to FedEx. I know they do the picture thing with their customers, but the emotional impact was far greater, positively, than I expected. Remember the Rickshaw Bags are custom made with hand pick color combinations. So seeing the pictures before they ship is a wonderful way to build the customer relationship. These are the first bags I bought from them. If the bags themselves are as good as they are suppose to be, they have hooked me for good.
This level of customer interaction does require someone monitoring the company twitter stream. But I believe it is sure worth it. What a differentiator and relationship builder.
