Removing Email Addresses

Using the "Remove Addresses" function, you can remove email addresses from the master mailing list (Master List) that are present in suppression lists.

For this to work, both the master list and the lists of addresses to be removed must be sorted by the column containing the email addresses.

To sort email lists in advance, enable the "Sort First" option.

Hashed Suppression Lists

The suppression lists used for removal may contain hashes of email addresses instead of the actual addresses (MD5, SHA-1, SHA-256, or SHA-512). In this case, you should specify the corresponding hashing algorithm.

Resulting List

Email addresses from the master list that are not present in the suppression lists will be written to a file (New Master List Minus Addresses Removed From The Old Master List).

You can also save the email addresses removed from the master list into a separate file (File Containing Addresses Removed From The Old Master List).

Domain Removal

You can enable the option to remove email addresses from specific domains (Also Remove Addresses From These Domains). For example, you may want to remove all emails from the top-level domain mil (the generic top-level domain for U.S. military organizations). In this case, add .mil (without quotes, starting with a dot) to the list of domains to be removed.

Sorting

You can enable sorting by domain (Sort By Domain) and multi-column list support (Multi Column Support).
