I like the breadth of the contact database, as it allows us to find verified emails and direct dials for very specific personas, such as job title, company size, and tech stack. The sequences feature is solid, with multi-step email, call, and LinkedIn task workflows that are easy to set up, and the analytics provide clear visibility into what's performing well. I find the Chrome extension makes prospecting on LinkedIn effortless. The API is well-documented, and integrating it with our internal tools was straightforward. Overall, these features save money and reduce admin overhead by replacing multiple separate tools and streamline our sales process by allowing SDRs to spend less time researching and more time talking to prospects.

Data quality is hit-or-miss. Most contacts are accurate but every batch has bounces, outdated titles, or wrong direct dials, so SDRs still have to validate. The dialer quality is okay but not at the level of dedicated tools like Aircall or Outreach. The UI can feel cluttered for new users, takes a couple of weeks to feel comfortable. Pricing for the higher tiers is steep when you scale users. And email deliverability with native sequences sometimes drops if you push volume, would be great if Apollo gave more visibility and tooling around inbox reputation.

I initially started using Apollo.io as a replacement for platforms like ZoomInfo and LeadIQ, and I really like it. It's very easy to use and has a good UX. The database is pretty huge, with great leads that are usable and relevant. I also appreciate that my past leads are auto-saved, and the contact pages are nice. It has a lot of really good use cases, with my favorite being the prospecting tool. The initial setup was pretty simple, especially since I started with the free version, and that ease of use convinced me to buy the subscription. Review collected by and hosted on G2.com.

I believe the general problem with Apollo.io and similar prospecting platforms is the relevance of the information. Sometimes, people leave companies and phone numbers or emails go silent, and those are not updated. Also often the leads are wrong. The numbers are wrong, and you can use credits but they don't lead you anywhere. But there really isnt a fix to this problem. Review collected by and hosted on G2.com.

The best part is that I can reach out to 50 different leads across 50 different organisations, with 50 different intent-based outreach messages.

It’s basically a sales universe: I can build lists and set up different outreach sequences. It also works as a repository, and I really like the waterfall enrichment for finding contact information. On top of that, it feels like a digital room where you can see the conversations teams are having across the organisation.

It integrates seamlessly with Sales Navigator (LinkedIn), Salesforce, and Slack, and it gives real-time notifications in Slack and via email based on any engagement.

Support is great too.

Without Apollo.io, overall performance and business output would have been significantly lower Review collected by and hosted on G2.com.

Apollo's AI Assistant still needs a lot of work. Overall, it feels premature compared to what others are already doing in this space.

The power-dialler also isn’t great. Specifically, it doesn’t consistently add the right information after every call, which makes follow-up and record-keeping harder than it should be.

Navigation and the UI could also be improved. Some parts feel less intuitive than expected, and the overall flow could be smoother. Review collected by and hosted on G2.com.

Apollo.io has completely transformed our outbound sales process. The database is massive and the contact data is incredibly accurate — I rarely hit a bounce. The email sequencing features let me automate personalized follow-ups at scale, which freed up hours of manual work each week. The integration with our CRM is seamless, and the Chrome extension makes prospecting on LinkedIn a breeze. Review collected by and hosted on G2.com.

The onboarding process could be more intuitive — it took me a couple of days to get the hang of all the filters and search options. Also, the pricing can feel steep for smaller teams, and the email deliverability sometimes drops if you're sending high volumes without warming up your domain properly.

I've been using Apollo.io to search for leads, contacts, updated emails, and contact details of employees, which has helped me a lot. I love using the Apollo extension on LinkedIn and Google; it's amazing because it helps me get the relevant email IDs and contact details and put them in sequences. The extension also helps update records on HubSpot and enrich data from Apollo. I can see the new companies people have joined on LinkedIn and identify key decision-makers with enriched data in real-time. The initial setup was super easy, just a one-click sign-up and extension download. Apollo.io is probably the best software for list building and everything we do, and it's definitely much better than any other tool we've used. I'm highly recommending it as it makes finding relevant contacts, enriching data, and keeping everything up to date much easier. Review collected by and hosted on G2.com.

Yeah. Sometimes it hangs a bit. So if I'm using Apollo AI on the website, on LinkedIn, on Google, and putting them on sequence, the speed is not up to the task. And, yeah, on the verification, it asks a lot of time. Every day, I have to verify myself that I'm not a robot, which is crazy. There are a lot of credits that get wasted if I need to get an updated contact number. So that can be a bit budget-friendly, that would be amazing. Review collected by and hosted on G2.com.

Apollo.io is most useful because it helps you find the right decision makers and reach out to them faster all from one place it gives you verified B2B contact details lets you filter leads very precisely by role, company size, industry, location etc and allows you to send and automate outreach without switching tools it saves time, improves targeting and makes B2B sales much more efficient Review collected by and hosted on G2.com.

Free tier is very limited, most advanced filters and features are locked Review collected by and hosted on G2.com.

Nothing whatsoever is good about Apollo. Their onboarding and support are inexcusably bad. Review collected by and hosted on G2.com.

Nonexistent onboarding, nonexistent human support, quirky user interface. To make matters worse, instead of deleting my phone number post-trial, they appended it to customer records. I get calls asking for specific people. One caller was nice enough to tell me they got their data from Apollo.io. Review collected by and hosted on G2.com.

Apollo.io is one of the easiest tools to use when it comes to searching for data. I also use other platforms like ZoomInfo, but Apollo’s data feels much more accurate and doesn’t give me false information, which is a really nice change and genuinely useful.

Now that Kaspr is gone, Apollo is number 1! Review collected by and hosted on G2.com.

Gathering more data would always be a good area to improve, since it could reduce the need to rely on three or four different tools. Review collected by and hosted on G2.com.

I use Apollo.io to fetch or verify my clients' email IDs, and it's legit most of the time and very helpful. I like its user-friendly interface and the accuracy of the information it provides. The initial setup is pretty easy; just sign up, and it gives you a tutorial, and you're ready to go. Review collected by and hosted on G2.com.

There aren't many phone numbers available in it and it also exhausts more credits for phone number info and also the monthly credits could have been more per user. Review collected by and hosted on G2.com.

I like that Apollo.io brings high-quality B2B data and multichannel outreach into one platform, so you don’t have to juggle separate tools for prospecting, enrichment, and sequences.

It also stands out for its strong filtering on a large contact database, plus AI helpers (research, scoring, and writing) that speed up lead research and follow‑up without much setup. Review collected by and hosted on G2.com.

Apollo.io’s data can be hit-or-miss, so you still get bounced emails and bad numbers.

The credit-based pricing feels restrictive and confusing, especially for smaller teams.

The UI is quite crowded, so there’s a noticeable learning curve and occasional glitches. Review collected by and hosted on G2.com.
