We use Concep List Cleaner to service our contact databases across the UK, US, Germany, Brazil and China operations. The service does what it says on the tin and has particularly useful in validating email addresses that have moved or are non-existent. The reporting on our campaigns has vastly improved since using this service and this has meant significant cost savings as now we only send to valid contacts."
