Exporting lists of customers or customers groups is very useful when it comes to setup your promotional operations or customer follow-ups.
To export the complete list of your active customers:
Select all groups in the left handside column 'Filter' to display the complete customers list
In the central panel, apply the filter 'Active' by selecting 'yes'
Then click on the 'Quick Export' icon on the toolbar
When the export window opens up, CTRL+C to copy
Open your spreadsheet and CTRL+P to paste the data
This is it, you now have the complete list of your active customers. You can use your mailing system to contact all these customers.
