The situation of Globus Baumärkte was as follows: There are a total of 4 online stores and a central customer service for handling inquiries from online shop customers. For online sales, inquiries appeared as emails and were processed centrally with Outlook. In the process, some e-mails were lost and there was no uniform standard for the quality of processing. It was impossible to track individual orders. In addition, the expansion of business by opportunity also required bulk processing of emails, which needed to be made easy and convenient for customer service staff. The goal was to process 1 000+ emails per day.
