In their words
Their pitch	The Asynchronous Contact Information Enrichment retrieves verified professional emails, phone numbers, and mobile numbers for up to 10,000 prospects per job — and, unlike the synchronous endpoint, it supports waterfall enrichment: prospects that Explorium data cannot enrich are automatically retried against a verified external provider, increasing overall contact coverage.
