I've been looking for a solution that would allow me to control redirects from different domain names without needing to speak to a developer or control the links at the server. Bl.ink does the job well and I've referred a number of portfolio companies to this deal on AppSumo. The app is designed well and easy to set up IMHO, but I know there were some users without DNS experience that probably struggled, but still managed to get things works. I've purchased a lot of apps on AppSumo lately, but this is definitely one I'm going to keep. Here's to hoping their team has electricity and heat since they're based in Austin, TX.
