The setup process involves minimal costs and is more affordable compared to other tools such as ZoomInfo.

The price is very affordable and the setup was easy.
Digital Marketing Manager at Unilever
I find the pricing, setup cost, and licensing of Outreach to be fair, as we can afford it considering the benefits versus the cost.
Account Executive SR. at ALUS
I cannot speak in detail about the pricing setup, as I was not involved in the purchasing decision, but I believe each user had individual seats rather than a shared license, allowing us to track individual activity.

Assistant Manager Process Improvement and Data at We Are Team Rocket Employees, Location, Careers
Reliability decreases as UI improves with useful features but needs better support
Apollo.io used to provide much better service before and their UI used to be less clunky. The user experience nowadays is not as good as it used to be. They used to provide more verified emails and numbers, but nowadays, it's not as reliable. We sometimes have to go through other tools to get more information as they have been lackluster in that area. Their information gathering is not as updated as it used to be. They don't have enough information. When it comes to performance, it's a very heavy app now. It takes time to load, stutters, and gets stuck frequently. Previously, it used to be much less laggy and easier to use. The UI live update was good before, but nowadays, I have to refresh the page to see if they had sourced the email or if old information is still being displayed. LinkedIn keeps updating their tools, rules, and regulations. Due to these reasons, Apollo.io experiences bugs, crashes, detail updates, and jumbled columns during updates. These issues are understandable from a developer perspective, but they create minor inconveniences for customers. I would appreciate if Apollo.io could restore the reliability of their email service to its previous level.

Targeted outreach has boosted engagement and improves collaboration across the sales cycle
According to my experience, the best features Outreach offers are its helpfulness and effectiveness. It also offers a set of free trial and an intuitive, user-friendly interface. It offers sales engagement, revenue intelligence, and revenue operation functionality in a unified platform. Outreach leverages automation and artificial intelligence to help revenue leaders decrease the inefficiency and ineffectiveness of go-to-market activities and personnel across the revenue cycle. Outreach helps automate sequences and ensures consistent and timely customer engagement. I also appreciate that it provides clear analytics on opens, clicks, and replies to refine the outreach strategy. Additionally, the use of AI captures real-time meeting notes and action items, saving time and preventing missed details.
