How Tessi achieved a 70% response rate on call campaigns with Diabolocom’s solution

Tessi, a major European business process outsourcing leader, faced the dual challenge of maintaining low costs and consistent service quality while scaling its operations across multiple countries and languages. To meet the demanding requirements of its clients, Tessi selected the omnichannel contact center solution from Diabolocom.

By implementing Diabolocom's cloud-based platform, Tessi gained a robust and scalable solution that enabled rapid deployment, seamless remote work transitions, and efficient management of over 10,000 daily calls. The partnership with Diabolocom resulted in a 70% response rate on call campaigns, provided advanced data analysis for continuous improvement, and allowed Tessi to offer a flexible, omnichannel customer experience that became a key part of its service offerings.
