I agree with SalesCampaigns below. I'm blown away with some of these bad reviews.
It's clear to me most of them don't know the proper rules of cold email- list cleaning, warming up, proper email providers (check out zapmail btw, real happy with them), etc.
This is a KILLER deal and product. It was a little slower in the beginning, but since then, there have been massive updates to the product and infrastructure and it's cool to see it continue to grow.
The founders and support staff are responsive and helpful. I don't know my exact ROI for this tool, but it's easily 1,000%+.
