Toolkit is not so much a toolkit as it is just a tool. Its good for getting reports and reviewing your contacts for your email campaigns. You can even work on a campaign but dont expect all of the features/services that you get from Constant Contact online. Its definitely a great tool and for mobile use I think it serves its purpose for email reports. To be honest I could do without the mobile campaign editing because it feels more comfortable on a computer than on mobile but I would have liked to see other services integrated like survey results. Its great that this tool exists but it still has much room for improvement before it can be called a toolkit.
