Chert
Chert provides iMessage infrastructure for teams that want to build, automate, and send conversations over Apple’s messaging network. It supports REST API and webhooks, with SMS fallback when a recipient is not on iMessage.
What Chert does
Chert is iMessage infrastructure for teams that want to build, send, and automate conversations on Apple’s messaging network. The site describes it as a single API for reaching people at scale while preserving the familiar blue-bubble experience and keeping the interaction personalized.
It is positioned for product teams and GTM teams that need to book meetings, send onboarding or support messages, or run AI-driven conversations in iMessage. The product also exposes webhooks and REST APIs so messaging can connect to CRM systems, sales tools, voice agents, and internal data stores.
Core capabilities
One API for messaging workflows
Use a single API surface to manage messaging flows built for product and GTM teams.
Native interaction signals
Keep track of read receipts, tapbacks, typing indicators, and native reactions inside the thread.
Group chats
Move conversations between threads with named senders when multiple recipients are involved.
SMS fallback and channel visibility
Route messages to SMS when a recipient is off-platform, while showing the channel used in the API.
Attachments and delivery telemetry
Send photos, PDFs, links, and other thread attachments with live delivery state updates.
Common use cases
Lifecycle onboarding
Use Chert to send welcome messages and guided prompts as soon as a person signs up, so onboarding happens inside a familiar messaging thread.
Customer support
Resolve customer questions in iMessage instead of moving users into a portal or ticket queue, using the same thread for back-and-forth support.
Conversational AI assistants
Build conversational AI that can book, reschedule, and answer questions in a natural thread-based format.
Outbound outreach
Run outbound campaigns from GTM teams over iMessage when the goal is to get replies without relying on cold email or visible SMS automation.
Operational notifications
Use the product to move operational notifications, such as delivery coordination, from SMS into iMessage group threads.

FAQ
Is this real iMessage or SMS branded as iMessage?
Chert sends messages over Apple’s iMessage protocol and presents a blue-bubble thread. If the recipient is not on iMessage, the system falls back to SMS and surfaces that in the API.
How is Chert different from sending SMS through Twilio?
Chert is positioned as an iMessage infrastructure layer rather than an A2P SMS provider. The site contrasts it with Twilio by pointing to peer-to-peer iMessage threads, read receipts, tapbacks, and the recipient’s normal inbox.
How do teams connect Chert to their existing tools?
The site says Chert exposes a REST API and webhooks for inbound and outbound events. It also mentions native sync for common events such as lead created, meeting booked, and opt-out received, with onboarding support available if you prefer not to build the integration yourself.
Is pricing published on the site?
The site says there is a 20-minute kickoff on the main site and a book-a-demo contact flow. The pricing page and public pages shown here do not list plan prices or limits.
