Mass lead import in CRM is a bulk data upload feature that allows businesses to efficiently transfer large volumes of lead information into a CRM system. This function streamlines lead management, data migration, and contact organization, making it easier for sales and marketing teams to work with accurate and structured customer data. Businesses use CSV file uploads, API integrations, and automated data mapping to import lead names, email addresses, phone numbers, and behavioral insights. A well-optimized bulk lead import process ensures data consistency, duplicate detection, and seamless CRM integration, enabling faster lead nurturing and improved sales workflows.
