Poli covers multiple customer service channels such as WhatsApp, Facebook and Live chat. However, this represents a small downside, since it doesn't have a service for Instagram, Telegram, or other major channels. Moreover, the service is also slightly expensive, as it charges a fairly hefty percentage for each account. The differences between this tool and Callbell are many.
Among these we have the price which, as far as Callbell is concerned, is much cheaper. Furthermore, Poli's customer service is not excellent and the focus of this tool is projected towards customers who own large companies, unlike Callbell, which is dedicated mostly to SMEs. Plus, Callbell offers a multi-agent omnichannel platform to manage all your chats.
