About

DB-Cross-Ref is a Python script that checks if the emails found in file A also exist in file B.

File Usage
A File containing emails to check
B File to check the emails against

Note that this relies on both files to have a maximum of one email per new line.
References to Spotify-Account1.txt and 000webhost.com.txt already in the script are legitimate and left in as an example.

The sort of counts that is returned:

  • Matched emails
  • Matched duplicate emails
  • Mismatched emails
  • Mismatched duplicate emails
