I like that it's easy to use once you get started with your first campaign! It has helped us grow our pipeline of leads by leaps & bounds in just 3 months since we got onboarded into their program (and they've been great about helping out as well).
The support team can sometimes be slow at responding but overall this product makes sense from both an ROI perspective AND user experience standpoint so there isn't much room here if things aren’t working right or need some improvement/adjustment made along those lines either :) We did not have any issues using them during trial period nor after launch when getting new users up-to speed was one goal within my organization which had never really existed before now via SFLOW!!
