Pros & Cons from Real Users Pros Apollo.io is very reliable and simple to use tool to identify the target POC in target company list. The details are very correct and help in connecting with the POCs faster. Integration with hubspot, email and linkedin helps in saving time and make the overall process very fast and efficient. Apollo is great at what its primary use case is, creating, scheduling and sending outbound emails. We can get new campaigns set up quickly and utilize the A/B testing capabilities on a regular basis. It also shows good metrics around each of our campaigns The sequence builder and email automation capabilities of Apollo work well and is the primary part of the application that we use. We have also tested the AB testing feature and this has helped improve our open rates by more than 10 percent. Good and vast database. Great features like filters, export, sort, etc. Easy to use along with learning it. UI, UX and Data are the main selling points. Starting with data, Apollo has one of the best enrichment systems out there, it integrates seamlessly with your LinkedIn to enrich the contact or business information of the page you're on. Apollo also works very nicely with your email, I am able to see recently opened emails and can also track recently sent emails as well as emails I can mark for follow-ups directly on my Gmail. Finally, the UI & UX system of Apollo is great, it's sleek and modern. Cons Sometimes the email ids are not correct and some profiles did not have contact numbers and that delays the process. Sometimes the dataset isn't as large as what we can see in Linkedin for given roles/industries. At times it can appear slow to load data. Often we can find contacts in Linkedin but are then unable to find them in Apollo so the quality of the data can sometimes be a bit hit or miss especially if you are targeting smaller companies and not just large publicly listed ones. Slow at times, and Support is not that great, rest is fine. Not a lot not to like about Apollo, I think external integrations that Apollo does not have might be an issue, so if you're deciding on Apollo you might have to do quite some heavy lifting switching.
