Messaging Solutions
Every channel your customers in South Korea use
Businesses in South Korea rarely rely on a single channel any more. Cyberscape lets you send SMS, WhatsApp, RCS and email from one account, so each message goes out the way your customer is most likely to read it.
Messages can be written in Korean and English, and every send is tracked with delivery reports, so you can see what reached people and what they did next.
