Where does customer data come from?
Normally, if the subscriber base is filled according to all the rules of ethics and honest business, the client provides the data himself. To make clients more willing to share their personal data, you need to come up with a good reason for this - some kind of gift, discount, etc. This is a lead magnet. It is even better to gamify the process.
If you forgot to immediately collect information about your clients (subscribers) and their interests, you can launch a survey, media campaign and other marketing activities, within the framework of which you can again collect everything that is missing: full name (or at least first name), gender, etc. You can automatically determine: place of residence (by means of metrics/statistics - based on IP address), interests (also based on analytics systems in conjunction with landings and targeted advertising).
For more complex tasks, there are general databases and special services where you can search for missing information about clients, as well as standardize it (if possible, correct errors and bring it to a single sample record). Such services are usually paid. In extreme cases, you can manually enter the email in the search (in social networks, in the general search, etc.). But databases with leaked personal data are not the best option from a legal point of view (it is definitely not worth using).
Why segmentation is needed
Each audience segment is a separate category of users that are united by some common criterion (or a combination of important criteria). For example, car owners, women, game lovers, nursing mothers, etc. Knowing the interests of such a category, it is easier to find a common language and press on the necessary interests. Accordingly, you can significantly increase mailing rates and sales rates (after all, any marketing letters are needed to promote the services or goods of a specific company).
When to do it
Segmentation should be done at the audience collection tunisia phone number data stage. Correlation with different categories should definitely be done in the future (segmentation work should not stop) – each user may have different interests, and accordingly, can be correlated with different segments.
How to perform segmentation
Audience segmentation is carried out using subscription forms, as well as landing pages, targeted advertising, split testing (A/B/N tests), analytics/statistics systems, online surveys (quizzes), etc.
By default, large segments are divided in the contact database based on the sources they are obtained from: all or specific pages of the company's official website, partner websites, landing pages, messengers, social networks, etc. The most effective way to select a segment is to combine a landing page with targeted advertising. You create a separate landing page to which you direct only those clients from the advertising network who meet the criteria defined in the targeting system: gender, interests, geographic location, etc. Need more segments? No problem, just create your own landing page and advertising campaign for each.
If you need to divide an old common base into segments
Since the initial data was not established when collecting the audience, it can be established using additional marketing activities: surveys, quizzes, contests with valuable prizes or discounts, etc. Another non-obvious method is A/B testing. You build hypotheses based on interests and distribute all those who responded to the actions into different groups.
