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.

Before downloading, you can either choose if you want to export all result Classifications (Deliverable, Risky, Undeliverable and Unknown) or restrict the results to some of them. You can even define the status codes you are interested in, by way of the "Show advanced options" action, which opens an additional panel.

Here is a screenshot showing how that looks like, in our Client Area:


The report contains one row of data for each email address of the list and is available in three file formats:

  • CSV (Comma-Separated Values): an ubiquitous format compatible with most spreadsheets and database softwares;
  • **Excel **(.xlsx): Microsoft Excel spreadsheet, compatible with Microsoft Office version 2007 or newer;
  • Excel 97-2003 (.xls): Microsoft Excel spreadsheet, compatible with legacy Microsoft Office up until version 2007.

For every email verified and downloaded, the export file includes all fields described in the next sections.
