With Mailmanagr, you can easily integrate Basecamp into your workflow; it lets you set up e-mail addresses and create messages, milestones and todos simply by sending an e-mail. Why force your clients into using a web-based tool when they’re comfortable just sending you a message? Why should you have to continuously copy and paste information from your e-mail into Basecamp? Mailmanagr bridges the gap.
We tend to announce things first on twitter, but when things leave beta, we'll post about them here.
