Expectus works on several fields of checking the marketing quality of a given record.
The basis of any qualitative analysis is lexical, syntactic and structural analysis of each record. About a dozen different algorithms check the correctness of the entered data. Verifying id e.g. a user has not made a mistake or if such data exists at all.
The system allows for eliminating non-existent, false e-mail addresses, indicating the records that may be an attempt to force payment by unscrupulous publishers in partnership programs.
Apart from checking the syntactic correctness of GSM numbers, they are also checked directly by your mobile operator.
During qualitative research we query data warehouses on the available behavioral profiles for the analyzed records. Such information allows you to determine the interests of some records and check their activity across the Internet.
The combination of multi-channel record check described by several traits (e-mail address, city, postcode, mobile phone) allows for a realistic assessment of marketing quality of the entire analyzed record.
