Thanks for your question. While I’m not intimate with each of those applications I can assure you they are nothing like calc{list}. In fact, we have applied for a patent on our calculating lists.

Calculating lists are the key here. We need to stop thinking of contact lists as a stagnant list of names with a title. With calc{list} you can easily combine lists and add logic that calculates to create new lists. Additionally, a calc{list} can be dynamic. This means that if you change one list many other lists may automatically be updated, hence dynamic.

Once you begin to reflect on dynamic calculating lists you’ll be astounded by the work they can save and the possibilities that extend even outside of email lists management.

All the applications you mention are great products and calc{list} would be a great addition to anyone using them and Swiftpage. Calc{list}’s calculating lists lets you leverage contacts and lists like never before.
