Common list makes it possible to load several types of identifiers in one file.
The requirements for the Common List files:
- File format: csv
- List size: from 2 000 to 5 000 000 unique items.
- One item per line.
- Separator columns - comma; lines - line feed.
- Encoding: UTF-8.
- File size: up to 128 MB.
In the first line of the file, you must specify identifiers - column headings: example file
One line should contain id of only one user.
It is not possible to build a Look-alike based on a common list - we recommend using other types of lists.
