LinkedIn removed Apollo.io's official company pages in March 2025 for data scraping violations. The same browser extension that built Apollo's database now sits at the center of active GDPR complaints. For buyers already frustrated by phone numbers costing 8 credits versus 1 for email and credits that expire monthly, the data sourcing controversy is accelerating evaluation cycles.

Before you sign
Five questions to ask any vendor, including Apollo.io, before committing to a contract.
Does the platform publish its pricing, including what each credit type costs and when credits expire?
Apollo's biggest buyer complaint is that the advertised per-seat price ($49-119/month) does not reflect what teams actually spend once phone credit consumption, overage rates, and non-rollover policies are factored in. Any platform using a credit model should answer this in its pricing page before you ever talk to sales. If the vendor avoids specifics on credit expiration and overage pricing, the billing surprise typically arrives in month two.
How was this contact data collected, and is the collection method explicitly GDPR-compliant?
Apollo's March 2025 LinkedIn removal highlighted a fundamental tension in the sales intelligence category. Many platforms build databases through automated scraping of LinkedIn and other public sources, which is efficient but raises consent issues under GDPR. Ask the vendor to describe their data sourcing method specifically, not just to claim compliance. Platforms like Cognism explicitly phone-verify contacts and obtain consent; others rely on third-party co-op networks. The sourcing method determines both data freshness and your regulatory exposure.
What is the actual deliverability infrastructure, and does your sending reputation affect other customers?
Apollo routes outbound email through shared infrastructure, which means one customer's bad list practices can degrade deliverability for everyone on that server pool. Ask the vendor whether sending happens through shared IPs or dedicated infrastructure, whether email warmup is included, and what controls exist to isolate your reputation from other users. Platforms like Instantly.ai let teams spin up unlimited sending accounts with dedicated warmup, directly addressing this risk.
What phone number accuracy does the vendor guarantee, and how is accuracy measured?
Phone accuracy rates in the industry are frequently self-reported and almost never audited independently. Apollo's G2 reviews report connect rates of 65-70% on phone data. ZoomInfo and Cognism claim higher rates through real-time validation. Ask the vendor to show you a blind test on a sample of your target accounts, not just published statistics. Also ask whether the accuracy guarantee applies to mobile direct dials or includes headquarters switchboard numbers, which are far less useful.
Does this platform handle outreach, data, or both, and what does a complete workflow cost?
Apollo's appeal is combining a contact database with outreach sequencing in one platform. Most alternatives do one or the other. Hunter.io gives you emails but not sequencing. Lemlist gives you outreach but not a database. Clay gives you enrichment but not sequencing. Before evaluating any single tool's price, map out the complete workflow: prospecting, enrichment, outreach, and CRM sync. A tool that appears cheaper than Apollo may require two or three additional tools to replicate Apollo's full functionality.
