Another tool built by AppSumo, List Builder is an email marketing tool that helps you build up your mailing lists. It captures (engaged) visitors right before they are about to leave with pops that are triggered by clicks and timers. It is a very easy tool to use as it has a drag-and-drop functionality and features that can be customised to your brand.
Thanks Kelly, Mailchimp have definitely come a long way with their UI over the years, it’s just their service that hasn’t caught up ;) I haven’t had the chance to play around with Pure360 as much as I’d like, but I’ve heard the same things echoed by several friends who use their service. Looking at their client list, I think they’re more aimed at large companies though.
