Who each tool is really for
AiSensy
AiSensy is generally chosen by teams running WhatsApp as a marketing channel. The work is planned rather than reactive: build a segment, schedule a template broadcast, watch delivery and engagement, follow up. It suits businesses with a sizeable opted-in base and a promotional calendar, where the number of messages sent is closely tied to revenue.
Interakt
Interakt is commonly chosen by online sellers whose WhatsApp traffic is created by transactions. Customers ask about a product, place an order, then ask where it is. The value lies in handling that sequence reliably and with as little manual effort as possible, rather than in crafting individual replies.
