I've been searching for a tool that will allow me to send mass tweets to multiple @accounts?
For example, I use Topsy to see who's shared my content and want to send a follow up tweet to everyone who has, but find it time-consuming to do this manually.
What I have in mind is something where I can upload a spreadsheet of Twitter names, write one tweet and for this to be tweeted at everyone on the list.
I haven't found what I'm looking for so far. Does anyone know of such a tool?
