If you are not currently using CRM segments in Yandex.Audience, this newly simplified process gives you a great reason to try.

The columns in the CRM segment file are optional, and it is up to you whether to combine data: you can create combined CRM segments, or separate ones for only phone numbers or only email addresses.

In practice, this means that CRM segments will soon replace the separate types – Email addresses and Mobile phone numbers. In about a month's time, we plan to remove the option to create them. Any of your previously created segments will continue to function as usual.

If you  would like more detailed information about CRM-based segments, take a look at the help section.
