AiSensy

AiSensy runs WhatsApp marketing on the official Business API. It is a WhatsApp marketing and engagement platform for broadcasting campaigns, automating replies and handling customer support from a shared inbox.

The free plan covers the API, a Blue Tick application, $1 in conversation credit and unlimited service conversations, meaning live chat replies to user messages.

Contact upload, template messages, a live chat dashboard and a Click to WhatsApp Ads manager are included, though tags are capped at 10 and custom attributes at 5.

Basic costs $20 a month and adds unlimited agent logins, audience segmentation, retargeting, multi-agent chat, chatbot flows, Shopify and WooCommerce integrations and a Dialogflow chatbot connection.

Pro is $45 a month and brings a campaign scheduler, click tracking, smart agent routing, budget analytics, project APIs, birthday message automation and automatic retry of failed messages.

Enterprise is custom priced, with webhooks, downloadable reports, a dedicated account manager and unlimited tags, and is geared toward brands with 5 lakh or more users.

One catch: marketing, utility and authentication conversations are charged separately on every plan.
