The ListID field is required whenever you use the API, or any of the software which integrates with Imnica Mail.
Up to now, it has not been the easiest thing in the world to find. You had to either over over the list name, and read it in the URL display at the bottom of the browser, or, you had to open the list, and get the number from the URL bar.
We just rolled out a small update which displays the number in your normal lists view.
This is the 1st in a series of small, incremental updates, with some bigger ones, with HUGE jumps in functionality planned as well!Share
