GetProspect is a B2B contact intelligence platform focused on email finding, verification, and cold outreach. According to GetProspect, it provides access to a database of 780 million business contacts with LinkedIn integration and built-in email sequencing. It works well for teams that need straightforward email prospecting at a predictable cost, but as sales teams grow, they often run into limitations: phone data is limited to a small add-on, engagement capabilities are basic, and there is no native dialer or buyer intent layer. Teams looking to scale outbound, enrich CRM data automatically, or run multi-channel sequences tend to outgrow it quickly.
When evaluating alternatives, the key questions are: Do you need data only, or data plus execution? Do you run email-only sequences or multi-channel outreach including calls?
Do you need CRM enrichment on autopilot? The answers will determine which platform fits your workflow, and the six options below cover the full range, from purpose-built email finders to complete go-to-market systems.

Tired of hours lost verifying contacts before a single email goes out? Apollo surfaces accurate, ready-to-work leads so your team sells instead of searches. Nearly 5M users have already made the switch.

If you need phone number access alongside email without a per-user seat cost, ContactOut's Email + Phone plan or SignalHire's combined credits are worth evaluating.

The Living Data Network keeps contact records current across your sequences and CRM, so teams spend less time on manual data hygiene. Apollo's AI featureslayer on top: AI lead scoring, intent signals, AI-generated sequences, and call summaries reduce the manual work at every stage of the funnel.
Enterprise teams evaluating governance, SSO, advanced security, and admin controls should look at Apollo's Organization tier, which is built for multi-team deployments with role-based permissions and international dialing. Apollo is not a SMB-only tool, it serves companies across every segment, including teams at Fortune 500 companies.
Apollo is the most complete option for teams that have outgrown standalone email finders. As covered above, it adds a dialer, multi-channel sequencing, AI automation, buyer intent signals, and automated CRM enrichment to a database of 240M+ people, all in one connected system. Teams looking specifically to expand their sales prospecting process beyond email will find the most coverage with Apollo.
Yes. Apollo, Hunter.io, ContactOut, SignalHire, VoilaNorbert, and Snov.io all offer free tiers.
Apollo's free plan includes 900 credits/year and access to core prospecting and sequencing features. Hunter.io's free plan provides 50 credits/month.
Snov.io's trial plan includes 50 credits/month. Free tiers are useful for evaluation, but volume limits mean most active sales teams will need a paid plan.
GetProspect offers CSV and API-based enrichment, which requires manual uploads or developer setup to keep CRM records current. Apollo's data enrichment runs on a scheduled or real-time basis with bi-directional sync to Salesforce and HubSpot, applying customizable data-writing rules automatically. As one Apollo customer put it: "Apollo enriches everything we have: contacts, leads, accounts...And we don't really have to touch it, it just works.", Mark Turner, VP of Revenue Operations at Built In.
Apollo is the only option in this list with a native Power Dialer and Parallel Dialer built directly into its prospecting and sequencing workflow. Teams can move from finding a contact to calling them within the same platform, with AI-generated call scripts, voicemail drop, and CRM-logged call outcomes.
ContactOut and SignalHire provide phone number data, but neither includes a native dialer for executing calls.

GetProspect serves teams that need a focused email finder with built-in outreach, but sales organizations that need phone data, intent signals, multi-channel execution, or automated CRM enrichment will find it limiting. Hunter.io, VoilaNorbert, and Snov.io are worth considering for email-forward workflows at different price points and feature depths.
ContactOut and SignalHire add phone number coverage. But for teams that want a single platform covering data, intelligence, and execution across the full funnel, Apollo is the clear choice.
Apollo combines a verified contact database, AI-powered outbound and inbound workflows, a built-in dialer, and automated enrichment in one connected system, used by nearly 5 million users and 100K+ paying customers across every company size, including teams at Fortune 500 companies. Get started at no cost and see the difference a complete GTM platform makes.
