The best which is like in apollo is the Time saving part. Instead of using multiple tools, we can use this alone to gather information and we can do outreach as well at the same time

Intuitive Prospecting with Easy Setup

|Apollo.io
Apollo.io is super easy and intuitive to use. It helps me by providing up-to-date contact details of prospects, which I use primarily to get my ICP's phone numbers and email IDs. The initial setup was very easy.

Boosts Efficiency with Reliable Lead Generation

|Apollo.io
I appreciate Apollo.io for its ability to build highly targeted lead lists quickly. The verified email data saves a lot of manual verification time. Its advanced filtering allows us to bypass irrelevant profiles and instantly find decision-makers in specific industries. The platform's high delivery success rate ensures that verified email data keeps bounce rates low, hitting the right inbox without wasting time on dead leads. By replacing multiple single-purpose tools, Apollo.io offers discovery, verification, and sequencing all together, which makes it significantly more cost-effective for growing teams. The Chrome Extension, which installs in seconds, allows for easy scraping and enriching of profiles directly from LinkedIn. I find the massive B2B database and easy lead-list generation extremely valuable, as they save a massive amount of manual work.
