Seamless Prospecting and Integrations

|Apollo.io
I like that with Apollo.io, I don't have to go to other systems to find emails, phone numbers, and company info. I have it all in one source, which helps me track my prospecting and accounts better. The integration between Apollo.io and Salesforce is also a big ease. The initial setup was pretty easy, even though we had a couple of trainings and some questions. It's pretty strong, probably an eight or a nine out of ten.

Streamlines Prospecting with AI, Needs Data Accuracy Improvement

|Apollo.io
I use Apollo.io daily for prospecting, especially for writing up sequences, sending out emails, and making calls. The new feature with the AI assistant definitely helps because I can give a proper command to build a sequence and do what's best for my day-to-day activity. It helps me automate tasks, allowing me to focus more on finding quality leads and starting the outreach. The initial setup was pretty easy and straightforward, and I've seen the evolution of the solution over time.

Accurate Data, Easy Setup, But Navigation Challenges

|Apollo.io
I appreciate Apollo.io for its accuracy of data, which is essential when retrieving contact information for prospects. It's the most reliable data aggregate source I have used over the years. Setting up Apollo.io was easy, which was a big plus for me. On top of this, I give Apollo.io a 10 out of 10 for how likely I am to recommend it to a friend or colleague.
