Is this real iMessage, or just SMS branded as iMessage?

It is real iMessage. Outbound and inbound messages flow directly over Apple's iMessage protocol with the native blue-bubble UX. The platform only falls back to SMS if a recipient is not on an active iMessage device.

How is Chert different from sending SMS through Twilio?

Twilio provides an A2P SMS pipeline which is heavily carrier-filtered, requires 10DLC registration, and is visually automated. Chert provides a peer-to-peer iMessage thread inside the same inbox as friends and family, complete with blue bubbles, read receipts, and tapbacks.

What about deliverability and spam flags?

Because iMessage uses end-to-end encryption tied to Apple IDs, it bypasses traditional carrier filtering. Chert monitors diagnostics, rotates sending identities, warms them up gradually, and caps volume per identity to stay safely below automated abuse-throttling thresholds.

How can I integrate Chert with my current CRM?

Chert provides a REST API and webhooks to connect to any data store. It also ships with native sync for platforms like Salesforce and HubSpot, and offers custom integration assistance during onboarding if you prefer not to build it yourself.

Chert Product Information

What is Chert?

Chert is a stable iMessage infrastructure and API platform designed for product, growth, and go-to-market teams to reach people at scale. It allows businesses to build and deploy conversational iMessage AI agents for use cases like customer service, inbound lead capture, onboarding, and cold outbound messaging. The platform operates directly over Apple's iMessage protocol, delivering authentic blue-bubble message threads that support read receipts, live delivery states, group chats, typing indicators, tapbacks, and media attachments. Additionally, it offers automated SMS and RCS fallbacks when recipients are off-platform, and integrates with major CRMs like Salesforce, HubSpot, and Close to natively sync conversation histories.

How to use Chert?

To use Chert, developers can integrate its single REST API and webhooks into their applications to handle inbound and outbound messaging. Teams configure the system prompt, behavior, and tone to create conversational agents, provision real verified phone numbers through Chert, and wire the communication history back into their preferred CRM systems like HubSpot or Salesforce.
