We have a limit of maximum 5000 emails per domain that can be exported in the Domain Search, while on any premium plan. Free users can get 10 emails per domain.
When using the Bulk Domain Search, at most 100 emails can be extracted per domain. This is to encourage our user to build more qualified lists rather than big and low-quality exports. Each Bulk Domain Search is also limited to 25,000 domain names (or company names ) maximum.
