Efficiency improves with automation, but data accuracy needs enhancement

What I appreciate about Apollo.io most is its Chrome extension which is very user-friendly, and it has excellent sequencing capabilities that make it easier to stay consistent with outreach. The fact that it combines both database and outreach tools in one place is valuable. I utilize Apollo.io's lead scoring feature extensively. The experience with Apollo.io's CRM integration capabilities for managing pipelines is excellent. The ability to integrate with HubSpot, which I frequently use as my CRM, is outstanding. It also works seamlessly with Gmail and automation tools such as make.com or Zapier. As an SDR using Apollo.io, there is no need to copy-paste leads as everything can be automated and integrated. When leads are extracted, they automatically transfer to the CRM. This saves considerable time, and activities such as emails, calls, meetings can be automated in the CRM.

Their customer support is virtually non-existent

There are tons. First and foremost, Clearslide's billing practices border on predatory. They have a stealthy, indefinite term, auto-renew policy that attempts to charge the online credit card you originally signed with for a full year in advance every year unless you cancel 90 days prior to your original signing date. They also have sales reps who make verbal term commitments that fail to show up on the actual contract which they send over. They refuse to refund any monies which have been paid, even if you cannot use their service for any reason. Their core features are found on other tools out there for a cheaper cost and for less restrictive billing practices. Their customer support is virtually non-existent. If you have an important issue that needs attention, good luck. Stay far away from this company.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Their Waterfall Enrichment has evolved significantly—previously, they only used their own database, but nowadays, they use Waterfall Enrichment where multiple tools can be selected to provide email data, and I can select as many tools as I want, add APIs, link external tools, and add AI, which are all very useful features, especially when it comes to finding mobile numbers."

"Apollo.io has increased the accuracy in our targeting, be it using the LinkedIn URLs, the work email addresses, or the mobile and direct dial numbers that are available."

"The most valuable feature of the solution is the intent data it provides our company. I find it really interesting how Apollo.io can detect the intent of companies looking for your company's solution."

"I like the tool's UI. Its user experience is clear."

"What I appreciate about Apollo.io most is its Chrome extension which is very user-friendly, and it has excellent sequencing capabilities that make it easier to stay consistent with outreach."

"The fact that it combines both database and outreach tools in one place is valuable."

"Apollo.io has positively impacted my organization by improving sales efficiency, and we are thankful for Apollo.io because we have more leads or prospects."

"Compared to other tools, they are a bit accurate when it comes to CSV uploads."

More Apollo.io pros

"ClearSlide used to be pretty good for online remote presentations, online open alerts through email, and presentation prospect engagement reports."

Cons

"The data accuracy needs improvement, especially compared to tools such as ZoomInfo, though Apollo.io is more cost-effective."

"We want to find distributors, but in Apollo.io, from the LinkedIn data, I think it does not have a distribution option."

"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."

"The solution's initial setup process could be better."

"Apollo.io still needs to work on the CRM part because it has started building some CRM infrastructure for companies to use and track their sales activities."

"There was an issue with Apollo.io earlier this year or sometime last year when there was a breach regarding its use on LinkedIn, and many people were unhappy about it."

Pricing and Cost Advice

"Paid versions are likely to provide more accurate information and offer more convenience to users."
