In beta, looks very interesting. They already have 100+ paying clients. I can think of a lot of companies that could use this for their campaigns on Indiegogo and Kickstarter.
Shira - Thank you for this!
Green Inbox started as a side project helping a friend boost his campaign on Kickstarter (raised more than $50,000).
While experimenting various methods to promote the campaign, we discovered the magic that later on became www.greeninbox.com
We've only made our first baby steps and have a lot planned going forward. IMHO - we are not ready for PH. We still have a lot of "cleaning" to do before PH :-)
Have used greeinbox and feel that they deliver what they promise. Initially skeptical cause of the beta-look but I am satisfied. I loved the feature to send your FB friends an email.
