What is Salesmsg?
Salesmsg is turning a texting inbox into an agent platform that also answers the phone.
Salesmsg ships weekly and nearly every release now touches AI agents rather than the messaging inbox itself. In the last two months it consolidated agent creation into a single conversational builder, opened the account to external AI agents over MCP, and gave the AI calling agent escalation, live data connections, and session controls. Calling has moved from a side feature to a configured surface with routing actions, queues, and a custom IVR.
What is Respond.io?
WhatsApp-first inbox teaching its AI agents conversational patience — and losing the phone number as identity.
respond.io ships steadily against two tracks. The AI Agent track has been fixing the ways an agent behaves unlike a person: it can now wait up to five minutes for a Contact to finish typing before replying, send files and images as rendered attachments instead of bare links, recognize when it has been assigned a conversation or when a closed one reopens, and the Voice AI Agent got lower latency and more reliable reasoning. The channel track follows Meta's platform: WhatsApp carousel templates carrying 2–10 product cards, and support for WhatsApp usernames and Business-Scoped User IDs.

Salesmsg
6.3COMMS
Salesmsg is turning a texting inbox into an agent platform that also answers the phone.
◆ Current state
Salesmsg ships weekly and nearly every release now touches AI agents rather than the messaging inbox itself. In the last two months it consolidated agent creation into a single conversational builder, opened the account to external AI agents over MCP, and gave the AI calling agent escalation, live data connections, and session controls. Calling has moved from a side feature to a configured surface with routing actions, queues, and a custom IVR.
◆ Where it's heading
Two lines are converging. One is agent depth — agents that book HubSpot meetings over SMS, escalate calls to humans, pull from live documents, and now get built by describing them in a sentence. The other is CRM gravity: Salesforce custom objects, HubSpot workflows, and call-outcome logging keep pulling the product deeper inside systems customers already run, which makes it harder to swap out. Credit tracking per workflow and agent signals that AI usage is becoming a metered cost customers need to see.
◆ Prediction
Expect the Unified Agent surface to absorb the calling agent next, so voice and text agents are built and managed in the same place, and expect the credit-tracking work to grow into budget limits or alerts once customers can see what agents cost.
Respond.io
6.3COMMSSUPPORT
WhatsApp-first inbox teaching its AI agents conversational patience — and losing the phone number as identity.
◆ Current state
respond.io ships steadily against two tracks. The AI Agent track has been fixing the ways an agent behaves unlike a person: it can now wait up to five minutes for a Contact to finish typing before replying, send files and images as rendered attachments instead of bare links, recognize when it has been assigned a conversation or when a closed one reopens, and the Voice AI Agent got lower latency and more reliable reasoning. The channel track follows Meta's platform: WhatsApp carousel templates carrying 2–10 product cards, and support for WhatsApp usernames and Business-Scoped User IDs.
◆ Where it's heading
The AI work has moved past capability and into etiquette — the recent releases are all about an agent knowing when to speak, what to attach, and where it sits in a handoff, which is the difference between a bot customers tolerate and one they do not notice. Underneath it, the identity model is being rebuilt: WhatsApp usernames mean the phone number stops being the primary key, and respond.io has already threaded BSUIDs through Contact matching, templates, webhooks, and the Developer API.
◆ Prediction
With wait time, attachments, and assignment awareness in place, the next agent work likely targets the handoff itself — how an AI Agent escalates to or resumes from a human — while channel work keeps tracking WhatsApp's identity and commerce surfaces.
