What is Mailist App?
Mailist adds a clever--and really important--piece that's missing in all the other bookmarking tools: a follow-up mechanism that closes the loop. In this case, it generates a weekly email that takes random unread articles from your list and reminds you to get to them. Once you do, you cross off the link from your list.
Simple, yet powerful. Already used by over 900 active users and over 20 000 links saved.
