Is it possible to upload my own list of clients (CSV, Excel, spreadsheets, text, or any other format) with company name or URL, and have Leadrocks enrich it with phone numbers, emails, or other data? And then be able to download the enriched list with the additional data provided by Leadrocks? Basically, a bulk data enrichment feature — being able to upload a list and have Leadrocks enrich it at scale.
