A gradual approach to establish a growing engagement with a new client will generate better results than a cold approach. Voice should always be in the mix of course, because people like speaking to people and we would recommend using VOIspeed as it is feature rich and cost effective. In addition, a Conversational AI tool that will allow your agents to be effective on multiple media is needed.
The approach suggested here was found to be better even for people who had to pay taxes or an outstanding debt. People engage with a technology they can trust, that they have used before, and they are comfortable with. A technology that it is easy to activate and run. As an example, a WhatsApp business message or an SMS campaign will have better results than traditional cold calling or an email campaign asking people to visit a website. One issue is that an SMS you are limited in the text you can write and having a gradual approach can help with that too.
