Apollo Sued ZoomInfo Over Antitrust and False Advertising Claims
A federal court ruled in May 2026 that Apollo.io's antitrust and false advertising claims against ZoomInfo could proceed, meaning a judge refused to toss the case. The lawsuit centers on Apollo's allegations that ZoomInfo made misleading comparisons about data accuracy and engaged in anti-competitive conduct to suppress Apollo's growth. This kind of litigation signals genuine bad blood between two of the biggest players in B2B data — and raises questions about how both companies market their products.

Recurring Complaints About Auto-Renewal Charges and Trapped Annual Contracts
Across G2, Trustpilot, and Reddit, a consistent pattern of billing complaints has emerged: users say Apollo auto-renews annual contracts without adequate notice, sometimes charging thousands of dollars before the customer realizes it. Several reviewers reported being locked into $3,000–$6,000/year plans after free trials converted without explicit confirmation. Apollo's cancellation process requires contacting sales, which users say often results in delays that push them past the renewal window.
"We'd been on the free tier for months, then suddenly got hit with a charge for a full annual plan. Nobody had clicked 'upgrade' — at least not knowingly. Getting a refund took six weeks and multiple escalations."

Data Accuracy Problems: Stale Emails and Wrong Phone Numbers Widespread
The most common complaint on G2 and Capterra is that Apollo's contact data — particularly mobile phone numbers and direct dials — has significant staleness issues. Users in industries like tech and finance report bounce rates of 20–35% on email campaigns run through Apollo-sourced leads, well above what Apollo's marketing implies. The platform's 'verified' badge on contacts doesn't mean real-time verification, a distinction buried in the fine print that catches many buyers off guard.
"About a third of the phone numbers we dialed were either disconnected or belonged to someone completely unrelated to the contact we pulled. For what we were paying, that's not acceptable."

LinkedIn Data Restrictions Pushing Users to Abandon Apollo Workflows
A May 2025 MarTech report flagged that lead generation providers, Apollo included, were losing access to LinkedIn-sourced data as LinkedIn tightened its scraping enforcement. Apollo's contact enrichment features rely partly on LinkedIn-derived signals, and users began noticing degraded results in their sequences around this period. Some teams who'd built entire outbound motions around Apollo's LinkedIn integration reported having to rebuild their tech stack mid-year.

Sequence Deliverability Drops Blamed on Apollo Shared Sending Infrastructure
On Reddit's r/sales and r/emailmarketing communities, a recurring thread topic through 2024 and 2025 involves Apollo users seeing sharp drops in email deliverability after running sequences through the platform. Users suspect that shared sending infrastructure — where multiple Apollo customers send from pooled IP pools — means one bad actor tanks deliverability for everyone nearby. Apollo's documentation doesn't clearly explain the sending architecture, leaving users to diagnose deliverability problems themselves.
"Our open rates went from 38% to under 10% in two weeks with no change in our copy or list quality. Only difference was we started using Apollo sequences. Took us a month to figure out the IP reputation issue."

Customer Support Slow to Respond, Often Fails to Resolve Billing Disputes
Across Trustpilot and Capterra, users on lower-tier plans consistently describe support ticket response times of five to ten business days. The problem gets sharper during billing disputes — multiple reviewers say they were bounced between a support agent and a finance team before getting any resolution, a process that sometimes stretched to 45 days. Free and basic-plan users report being effectively ghosted when they try to cancel or dispute a charge.
"I opened a ticket about a duplicate charge in January and didn't get a real answer until mid-February. By then, the charge had already cleared my card twice."

Free Plan Marketed as Generous But Credit Limits Hit Immediately
Apollo aggressively markets a 'free forever' plan, but users on Reddit and Hacker News point out the plan's export and credit limits are so restrictive — typically 50 email credits per month — that it's nearly impossible to do meaningful prospecting without upgrading. The free plan is more of a product demo than a functional tool, but Apollo's landing pages don't make that limitation front and center. Several users say they built workflows on the free plan before discovering they couldn't export data without a paid tier.
"The free plan is basically a demo that lets you see the data but not touch it. You don't find out until you try to actually use it for anything serious."

BBB Profile Shows Pattern of Billing and Cancellation Complaints
Apollo.io holds a BBB profile under its Covina, California listing. While the company carries BBB accreditation, the profile includes complaints focused on billing disputes and difficulty canceling subscriptions — a pattern consistent with what users report on third-party review sites. BBB complaints in this category frequently describe customers who say they weren't informed about auto-renewal terms before being charged for a new annual cycle.

Credit Rollover Policy Quietly Changed, Users Lose Unused Monthly Credits
Apollo's credit system — used to unlock contact info — doesn't roll unused credits to the next month on most plans, a policy that costs users who don't max out their monthly allocation. Several G2 reviewers noted the policy changed or was clarified in 2024 without proactive notification to existing subscribers. For teams paying $99–$149/month and only using 40% of their credits, the effective cost-per-contact is substantially higher than Apollo's advertised pricing implies.
"I realized I'd been burning $1,200 a year on credits I was never actually using. Nowhere during signup did anyone say credits expire at the end of each month."

Apollo's own sales team uses aggressive follow-up
Multiple reviewers note irony in Apollo's own sales process — the team uses high-frequency outreach sequences that many prospects describe as overwhelming.
