The Filterer is designed to withdraw from your lists any unwanted types of addresses or domains according to the options you indicate.

For example, you have a large list of different e-mail addresses but need to extract from it into a separate file only those which belong strictly to France (the .fr domain) and Germany (the .de domain).

Use the Filterer to solve this problem and many similar ones:

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

-          Specify your large mixed list as the Input file;

-          Specify the file to place the e-mails that suit you as the Output file;

-          Specify the file to place the e-mails which are filtered out as the Rejected file;

-          Set the necessary options to indicate the criteria for the e-mails to filter out;

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

-          Check the log and enjoy the results.


Please note that the Filterer works with whole types of e-mail addresses. If you need to remove from your list some certain single e-mail addresses, use the Remover.


Processing options

Setting the Filterer’s processing options you indicate the criteria for the e-mail addresses to filter out.

There are the lists of major top-level domains and mail services available as the options. Checking the options in these lists you give the Filterer the order not to place into the output file e-mail addresses which belong to the corresponding top-level domains and mail services domains.

The three options under the “ISP” label (“California ISP”, “Virginia ISP” and “Washington ISP”) allow you to filter out the e-mail addresses residing in California , Virginia , and Washington states. The lists of the domains located in these states are named “california-isp.txt”, “virginia-isp.txt” and “washington-isp.txt” and are situated in the subfolder “Config” of the application’s main folder. You can edit these lists as necessary, but if you add new domain names, please make sure that they are placed into the file according to the alphabetical order.


The following options are also available:

Starts with digit: Check this option to filter out the e-mail addresses which begin with any digit (0 to 9). This is useful if you want to avoid having in your lists useless services e-mail addresses which are usually present in message headers. It’s true that at the same time you may lose some valid e-mails, but these are negligible in comparison with lots of addresses like “” which may overfill your mailing lists.

All foreign domains except these: Check this option if you need to filter out all e-mail addresses which belong to national domains; specify the exceptions if necessary (either with a dot or without it; separated by commas or/and spaces). For example, specifying “.fr, .de” in this field you will solve the problem mentioned above and get rid of all domains which do not belong to France and Germany .

If you check this option but do not specify any exceptions, all e-mail addresses belonging to all national domains will be filtered out.

Custom criteria: Check this option to specify the word (or several words separated by commas or/and spaces) which make an e-mail address unsuitable for you. The Filterer will filter out all addresses which include any of these words in any position.

For example, if you set this option and write the line “company, info” in the adjacent field, the following addresses will be filtered out:

Processing results

The Output file will contain the e-mails that satisfy the options you had set (e. g. only the ones in the domains .fr and .de).

The Rejected file will contain all the other e-mails from the input file (e. g. only those not in the domains .fr and .de).

The original input file will remain unchanged.
