I first stumbled across this tool as wanting to have a centralized email / funnel tool. Hexosparks allowed us to bulk import all the contacts via .csv and also via the LinkedIn Extenstion. In addition, the visualization dashboard allow you to have overview how many emails sent, and which are the leads required attention (not to mention the built in template for quick TAT). Best of all, the team is very committed and patiently guiding non-savvy users like myself (shout out to Lusine for her patient and being very knowledgeable walking dictionary for Hexosparks). I definitely would highly recommend this if you havent get it yet !
