The Merger is used to compare two lists in files, find and report matches and differences and merge the lists to obtain one complete list.

The Merger is really useful if you have a basic list of e-mail addresses which you constantly use (let’s call it the Master file) and need to merge it with a newly received list containing some more e-mails. At that some of the e-mail addresses in the newly received list may be already present in your Master-list, so you need to exclude duplicates, if any.

The Merger will compare the two lists and extract from the new list the e-mail addresses which already exist in the Master file and those which are actually new (placing both existing and new e-mails into a separate list file). Then, if necessary, it will update the Master file with the new e-mails, optionally making a backup of the Master.

Thus, to solve the problem of merging two lists, do the following:

-          Open the Merger’s tab in the List Processing application;

-          Specify your newly received file as the Input file;

-          Specify your Master file;

-          Specify the file to place there the e-mail addresses from the new file which are not present in the Master file (new e-mails);

-          Specify the file to place there the e-mail addresses from the new file which are already present in the Master file (existing e-mails);

-          Set the option “Update Master file with the new e-mails”, if you need the Master file to be completed;

-          Set the option “Backup Master file”, if you need the backup of the Master file. The backup file will be stored in the same folder, with the same name and the extension .bak.

-          Click the “Go” button and wait for the processing to complete;

-          Check the log and enjoy the results.

Processing results

After the Merger has processed your lists the results will be placed into the specified files in the form of sorted lists, one item per line, no duplicates.

Indicating the output file names please note that if there is no file with the specified name in the specified path, it will be created. If the file with such name already exists in the specified folder, it will be overwritten. At that the backup copy of the file may be created according to the application options (the same refers to any other output file).

The original input file will remain unchanged.
