Yes. Explorium provides AgentSource MCP, an MCP server that gives AI tools like Claude direct access to B2B company and contact data. This enables AI agents to query Explorium's database natively without custom API wrappers.

Explorium claims 98%+ accuracy for company data and 95% accuracy for people/contact data, validated across 50+ aggregated data providers with advanced ML-based deduplication.

The default rate limit is 200 requests per minute per API key. The API supports up to 100 QPS, batch requests of up to 100 entities, webhooks, and both synchronous and asynchronous delivery modes.

Yes. Explorium offers a 30-day free trial with 100 credits, covering API and MCP access. Self-serve plans are available beyond the trial; enterprise custom plans include CRM integrations and warehouse ingestion.

High-velocity signals (intent, events, hiring) refresh daily. Semi-dynamic attributes refresh weekly. Stable firmographic fields refresh monthly or quarterly.

Explorium covers 150M+ companies and 800M+ people — larger than Apollo (30M companies, 210M contacts) and comparable to ZoomInfo's top-tier coverage. Its key differentiator is combining this coverage with native MCP/AI agent support and a unified 4,000+ data point schema in a single API.

Catch-all domains are configured to accept all inbound email regardless of whether the specific address exists, which makes standard SMTP verification unreliable. Findymail uses a proprietary catch-all recovery algorithm that goes beyond basic SMTP checks — testing email pattern consistency, cross-referencing public sources, and applying confidence signals — to classify catch-all addresses as deliverable or risky. Addresses classified as risky catch-alls are not returned as verified, protecting your sender reputation.

Findymail works without Sales Navigator for individual email lookups via the web app, CSV upload, or API. However, the bulk LinkedIn export feature — which lets you export entire search result pages directly from LinkedIn — requires a Sales Navigator subscription to function at meaningful scale. Free LinkedIn accounts have strict rate limits that make bulk export impractical. Teams serious about volume prospecting from LinkedIn typically use Findymail alongside Sales Navigator.

Findymail's pricing model is designed to align cost with value: you only pay when a deliverable email address is actually returned. If Findymail cannot find or verify an email for a contact, no credit is deducted. This model means there is no penalty for searching against contacts who have no discoverable email, and it incentivizes Findymail to maximize verification accuracy rather than simply maximizing output volume.

In single-provider mode, independent benchmarks place Findymail's email find rate at approximately 75%, which is lower than database-heavy tools like Apollo or Hunter but with substantially better deliverability on the emails it does find. In waterfall setups — where Findymail runs after one or two other providers to catch emails they missed or mis-classified — combined find rates reach 85–92%, while the overall bounce rate of the waterfall stays low because Findymail's verification is the final quality gate.

Unused credits roll over to the following month on all paid plans. However, your total credit balance is capped at 2× your monthly plan size. For example, on the Starter plan (5,000 credits/month), your maximum accumulated balance is 10,000 credits. If you consistently use fewer credits than your plan provides, you will eventually hit the cap and excess rollover will be forfeited, which is worth factoring into plan selection for teams with irregular outreach volume.
