You can upload a number of contacts or manually create contacts on SMS.to and organize them in lists and later use them as recipients of your messages/campaigns.

One contact can be on one or more lists and you can send messages/campaigns to one or several lists at the same time.

The system will always make sure that on phone number will only receive one message per campaign - even if you are sending to several lists and some of the phone numbers are on more than one of those lists. Duplicates will be eliminated on-the-fly in this case.

A good practice is for example to segment your customer database by country into a dedicated contact list for each country. But you can of course use these features for whatever segmentation is best for your specific use case.
