Chert
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.

Linq
Linq is a developer-focused messaging infrastructure platform that lets businesses and AI applications communicate with users through iMessage, RCS, SMS, and voice. Its APIs support features such as emoji reactions, voice notes, rich media, typing indicators, group chats, and other conversational interactions that feel more like native messaging than traditional business texting. Developers can integrate Linq into their applications to power AI assistants, customer workflows, reservations, alerts, support experiences, and other messaging-based services. The platform is designed for high-volume, low-latency delivery and offers enterprise features such as encrypted data handling and SOC 2 Type II compliance. Linq also provides tools for building conversational AI agents that operate directly inside messaging apps without requiring users to download a separate application.

Sendblue
SendBlue is a messaging platform that lets businesses send iMessage, SMS, and MMS using virtual iMessage lines, with or without writing code. It avoids the need for A2P registration and supports rich media like voice memos, videos, and high-resolution photos. It’s particularly designed for sales and marketing workflows; messages automatically fall back to SMS on non-Apple devices, you can port your existing phone number into the system, and it integrates with your CRM so you can message prospects directly. SendBlue claims users see a ~70% increase in response rate by using iMessage instead of traditional texting channels. The platform also supports sending media types (voice, image, video), maintains “blue bubble” design to mimic native iMessage, and limits brute-force messaging by capping daily messages per phone line. We allow our users to send unlimited texts to their contacts.
