I like using Apollo.io for email campaigning, and I find the cadence is built perfectly to reach out to prospects. It’s easy to perform multiple outreaches and keep all records captured under each prospect. I appreciate the easy-to-use and user-friendly interface as it allows me to navigate quickly through different tasks and learn the product easily. The navigation is good, and it helps me efficiently move between tabs to perform various tasks. The initial setup was easy, which made it simple to get started.

Latency in navigation is an issue. When I try to move to different tabs, it takes some time for the page to load, which makes me wait for a few seconds. Review collected by and hosted on G2.com.

I use Apollo.io for finding new leads, lead enrichment, and running campaigns for new clients. I appreciate how it helps me identify my target market through my ideal customer profiles and keeps contacts up to date. What I like most is the amount of leads it can fetch and the way it categorizes them by location, companies, designations, keywords, and more. It also allows me to manage my data by groups and campaigns. For example, when I want to run a campaign targeting a specific region, I can easily fetch leads based on their designation in New York State and move on to Florida, separating my campaigns by regions, companies, and other criteria effectively. The initial setup was simple, requiring just a sign-up and selecting a plan, making it easy to get started. Review collected by and hosted on G2.com.

Sometimes when I want to run longer campaigns, Apollo.io just fetches redundant leads. It means it repeats the leads over and over again. Review collected by and hosted on G2.com.

For smaller-scale businesses that can't afford to have the best-in-class ecosystem (e.g. Hubspot, Salesloft, ZoomInfo, etc...), Apollo has all the fundamentals: enrichment, outbound prospecting, rudimentary deal and pipeline management. Review collected by and hosted on G2.com.

The platform seems like it was built by teenagers that have never used enterprise software or who have never done volume prospecting. It does a lot, but it does a lot in a half-baked almost-there way. They've clearly prioritized volume of features over refining things to a high quality level. I use Apollo because of this - it does a lot of stuff OK, and there aren't too many other vendors that have the same breadth. But every day there are things that drive me crazy. It's a junkyard of almost-finished products.

I have mixed reviews on support - when the live reps engage, I've had good experiences - one exchange actually turned into a minor feature request that they implemented in less than a week - that was pretty awesome. But I hate the AI support agent - it's not trained very well on the Apollo capabilities. I'm assuming that the teenagers haven't really built good documentation as a foundation.

I find Apollo.io's ease of use really impressive and I think it's fairly priced. The data has been pretty solid overall, being right about 85% of the time. This accuracy helps protect my domain reputation for sending emails and ensures when I cold call, I get to the right person, making prospecting more reliable. The initial setup was really easy as it does most of the context for my business automatically. Review collected by and hosted on G2.com.

I'd love to see a data provider invest in local business data somehow. I know it's harder but it would be really helpful. Review collected by and hosted on G2.com.

Apollo.io stands out for simplifying the entire B2B lead generation and outreach process within a single platform. I started using Apollo.io for the first time in 2025, and it quickly became a reliable tool for managing sales outreach and client acquisition. The contact database is broad and generally accurate, especially for targeting professionals in the US, UK, and EU markets. The advanced filtering capabilities are a major strength. Searching leads by industry, job title, company size, location, and technology stack makes it easier to reach relevant decision-makers instead of spending time on unqualified prospects. The built in email sequencing and tracking features add further value by allowing outreach campaigns to run smoothly without depending on multiple third-party tools. The interface is clean, well structured, and easy to navigate, even for first-time users. Setting up workflows, finding leads, and launching campaigns feels straightforward and efficient. This makes Apollo.io suitable for both small teams and growing businesses aiming to scale their outbound efforts. Overall, Apollo.io has helped improve lead quality, streamline outreach processes, and maintain a more organized and professional sales workflow. Review collected by and hosted on G2.com.

After using Apollo.io for about one month, I stopped mainly due to pricing limitations and credit restrictions. Many useful features require higher plans, which can feel expensive for smaller teams. Additionally, some contact data was outdated, leading to lower response rates in certain campaigns. Review collected by and hosted on G2.com.

I really like the cloud integrations and API integrations that Apollo.io offers. It allows us to have our cloud assistant working side by side, which makes it easier to extract the information needed. I can simply ask it to get information from Apollo.io, build a new list, or find a specific phone number or email without having to log in and search manually. This integration with my AI interface, which understands my business, greatly improves usability and makes things just way better. Review collected by and hosted on G2.com.

Apollo.io doesn't have any features around LinkedIn like sending connection requests, sending messages, following, or liking posts. Adding those kinds of cold outreach solutions side by side with email features would be a game changer. Review collected by and hosted on G2.com.

I like using Apollo.io for its comprehensive B2B contacts database, enrichment, and campaign purposes. It gives me all the detailed information I need about prospects, including demographic, firmographic, and email and personal data access, so I don't have to rely on multiple tools.

I really appreciate finding useful features like companies, prospect research, and campaigns right on the home screen. Setting up Apollo.io was super easy and smooth.

When I'm trying to download bulk contacts, I need to go in settings then import & export section which is headache for me I don't know why for large files specifically I need to visit import & export section for download my file. Review collected by and hosted on G2.com.

I like Apollo.io because it brings together many features in a single solution. The database is impressive, and the lead contact details are up to date and verified.
