Opt-In List Filter

In case you are in search of a software solution to help you manage your lists, Opt-In List Filter might be a tool to take into consideration.

The application is capable of cleaning and filtering your CSV lists by applying customizable rules so that you can extract strictly the data you are interested in.

Once you install the software utility, you are welcomed by an approachable user interface that first asks you to indicate the source file you want to process, with the supported format being CSV. You then need to come up with a name for your output file, and you are ready to filter your lists.

Regardless of the content the CSV file bundles, there are two different kinds of filtering rules, namely keep and exclude, with the possibility of applying them to a line either as a whole or strictly to a part.

That means you have the following fields to choose from: email, domain, username, line, column 1, 2, 3, 4, 5, etc.. Aside from that, a multitude of match operations can be associated with your rule. “Equals,” “does not equal,” “starts with,” “does not start with,” “contains,” “does not contain,” and many others can be explored, with the option to make the entire task case-sensitive.

It is also important to point out that your rules’ expressions can be specified, but there is also the possibility of coming up with a file entailing a series of expressions.

In any case, once your filters are created, moving them up or down the list, editing or even deleting them should raise no difficulty whatsoever.

Opt-In List Filter is a lightweight piece of software whose purpose is to help you manage your lists of emails, contacts, URLs, and whatnot by applying all sorts of filters. The program ran seamlessly during our tests and was overall responsive, so giving it a go could be a good idea if you are looking for a solution of its kind.
