When you import an address file, promio.connect checks different things. If the address file is uploaded, choose Addresses > Lists, click on the imported target group, and look at the logfile.

In the example, you can see that 2012 addresses should be imported.

• 2011 addresses are left after the syntax check. So in some addresses, for example, the @ was missing.
• 1977 addresses are left after the blacklist check. 34 addresses are therefore in the negative list and will not be imported.
• the matching criterion is mail
• 563 addresses have already been in the database.
• 1414 new addresses were found.
