- A webhook service for replies and delivery status
To hold a conversation
The agent and its memory
- Model choice, prompts, guardrails and hosting
- Conversation state and customer memory
- Order and booking actions in Shopify, Toast, OpenTable and the rest
To run marketing
Campaigns and measurement
- Audiences, segments and scheduling
- Templates and approvals
- Reporting that ties messages to orders and bookings
With Kubbly
Kubbly runs these for each brand
Sender setup, consent and quiet hours, BrandRep, the commerce and booking connections, and campaigns planned by the AI CRM assistant.
Which one fits
Choose a messaging API if you have engineers, need many countries or WhatsApp today, or want full control of the model and the data. Choose Kubbly if you want verified RCS, campaigns and AI conversations that complete orders without building or running them yourself.
This is not a choice between networks. Kubbly itself sends SMS through Twilio and RCS through Vibes. The choice is between building the product layer and using one that is already built.
Case study: at Melting Pot, a guest asks for a table in a branded conversation and Kubbly BrandRep completes the reservation in OpenTable.
Coming next to Kubbly: WhatsApp, a developer API, and Apple Messages for Business. Today Kubbly sends through RCS for Business, SMS and email.
Questions buyers ask
Does Kubbly have an API?
Not yet. A developer API is coming next. Today Kubbly connects to Shopify, WooCommerce, Toast, Square and OpenTable, and the Kubbly team sets up each brand. See the supported integrations.
Which countries does Kubbly cover?
Kubbly sends RCS and SMS in the US today. If you need many countries now, a global messaging API is the better fit.
Can a consumer app use Kubbly?
Yes. A consumer app can reach its users in Apple Messages and Google Messages from a verified sender, run campaigns, and answer replies with BrandRep without building messaging infrastructure. Order and booking actions depend on the systems you connect.
