About
Chert is iMessage infrastructure for reaching people at scale, providing the API and workflow layer for sending, receiving, routing, and observing real iMessage conversations. It lets teams build and deploy AI on iMessage while maintaining quality, trust, and personalized interaction, with blue-bubble threads from verified numbers delivered like native iMessage. Typing indicators, reactions, reply context, read receipts, and attachments stay intact for AI or human follow-up, while multi-recipient threads support named senders and clean handoffs. If a recipient is not on iMessage, conversations can fall back to SMS or RCS, with delivery status surfaced per message. Workflow primitives include phone number pools, reply routing, webhooks, and audit trails, and the same API can start a thread, interpret a reply, and move the workflow forward.

About
Sendmux gives AI agents their own inbox and a controlled way to send email. Each agent can receive messages, read threads, handle attachments, send replies, and react to new mail through signed webhooks or Server-Sent Events.
Teams can send through Gmail OAuth, Outlook OAuth, SMTP providers, or managed Amazon SES. Sendmux can spread sending across providers with weighted routing, sender-domain routing, health checks, failover, and quotas by second, minute, hour, or day.
Developers get Mailbox, Sending, and Management APIs, OpenAPI docs, SDKs, the sendmux CLI, MCP tools, and Sendmux Skills. The platform also covers tenant isolation, mailbox-scoped API keys, custom domains, logs, metrics, and usage-based pricing with no per-seat or per-mailbox fees.
