What information does the validation report contain?

After our hosted email validation service finishes processing a list of email addresses, it allows the owner of the list to view and download a detailed validation report with complete information about each email address under test.

The report is available in either Microsoft Excel (2000 or higher) or CSV (Comma-Separated Values) file format, and contains one row of data for each email address of the list; every row includes the fields described hereafter.

Heading fields

Field Description
InputData The input email address, as supplied to the hosted email validation service.
For example: alice@example.com
CreatedOn Creation date and time of the item.
CompletedOn Completion date and time of the item.

Validation result status fields

Field Description
ResultStatus The status code for the validation result (please see this knowledge base article for additional details).
For example: SmtpConnectionTimeout

Grouping fields

The following fields act as short-hands for the direct test of the ResultStatus field (shown above), ease the processing of the report and make it more readable at the human eyes too.
