I'm a co-founder at Streak.com, and I think the problem you're describing is especially well suited for Streak (if you're using gmail). Obviously I'm biased but here's why: 1) We show you the context of your lead right next to the email you're reading in your inbox 2) Our primary interface to your leads is very spreadsheet like. You can search, sort, filter, group, etc to slide and dice your deals in different ways. 3) We extract useful information about your leads automatically (like the date you last emailed them). Combine this with (2) and you can filter and sort your leads so that you know exactly who you need to get back to next. 4) Our saved views feature might be especially useful to you - effectively you can put the leads that need attention right now at the top of your inbox, see here: http://blog.streak.com/2013/07/using-saved-views-to-organize-yourself.html http://blog.streak.com/2013/07/using-saved-views-to-organize...
