Impressionwise Email Verification and Spam Trap Removal


Bulk FTP Transfer

Designed for automated, batched submissions of larger volume data sets. This service is designed for those clients who receive data on a regularly scheduled basis (such as hourly, daily or weekly) which allows 24/7 access to Impressionwise cleaning services without the wait time of traditional processing in a secure manner. This service comes in two submission variations; first is the traditional sending of the data to Impressionwise servers for processing, the second option allows for the data to be housed on the client’s FTP server with Impressionwise automatically downloading and processing.
