I like the overall approach of Kanbox to better organise your Linkedin outreach in an easy to manage and oversee CRM, and keep track of your sequences. Thing is, with the Tier 1 approach, you immediately run into limitations. Like not being able to upload saved leads from Sales Navigator.

The tools calls itself the "#1 The Smartest Scraper for Linkedin and Sales Navigator - Import leads from LinkedIn searches, posts, events and groups" - but the nyou realize its not even included in Tier 1.

TL;DR: Tier 1 is pretty much useless; Tier 2 helps to get structure into your network; but still no autmated outbound which comes at extra money.
