Apollo.io

It has I guess one of the biggest e-mail bases, but might be a bit better in sales experience, but great tool in general

Usually good emails but not consistently

Have come across Apollo as a promising tool and seeing value-add in our existing process.

Very easy to use, highly recommended

Apollo provides access to a vast database of business contacts and leads, making it a valuable resource for sales. Thanks a lot.

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.

Apollo's affordability makes it a perfect fit for my personal use. It provides the features I need without breaking the bank.

Reliable in terms of providing contact info.

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.
