Very usefull tool that allowed us to scale our outbound strategy from lead gen to sending.
Their product evolve very fast and they keep innovating.
Why not 5 stars?: Replying to emails from multiple domains is far from being optimized.
I use Apollo to find contact info for leads that I generate. I like how apollo will work over LinkedIn and any site period!
Verified email and social accounts saves a ton of time having to use an email checker.
I wish the user interface wasn't so small and cluttered. Working with a lot of leads makes the "working area" feel small and difficult.
