Heymarket vs Delta Chat: at a glance
What is Heymarket?
Heymarket layers AI agents and structure onto business messaging
Heymarket's feed mixes marketing content with a real product track: it has introduced Escalations for routing urgent conversations, Conversation Tags for structure, inbound webhooks for tech-stack integration, and email-alongside-SMS in Salesforce and HubSpot. A behind-the-scenes post on training its AI agents (and dogfooding them) signals where the roadmap is heading.
What is Delta Chat?
DeltaChat is maturing calls and channels while pushing server logic into Chatmail.
DeltaChat ships frequent versioned desktop releases. Recent work splits across maturing real-time calls, channel/broadcast features, and offloading server-side housekeeping (message deletion, folder fetching) to its Chatmail backend so the email-based app behaves more like a native messenger.

Heymarket

Heymarket layers AI agents and structure onto business messaging
◆ Current state
Heymarket's feed mixes marketing content with a real product track: it has introduced Escalations for routing urgent conversations, Conversation Tags for structure, inbound webhooks for tech-stack integration, and email-alongside-SMS in Salesforce and HubSpot. A behind-the-scenes post on training its AI agents (and dogfooding them) signals where the roadmap is heading.
◆ Where it's heading
The product is evolving from team SMS toward a structured, AI-assisted omnichannel support layer that plugs into CRMs and arbitrary systems via webhooks. Escalations and Tags add operational rigor; the AI-agents work points toward more automated handling of inbound volume. Expect deeper AI-agent capabilities and broader channel/CRM coverage.
◆ Prediction
Next moves likely productize the AI agents Heymarket has been training internally, with more automation around triage, escalation, and response drafting across its messaging channels.
Delta Chat
2.5COMMS
DeltaChat is maturing calls and channels while pushing server logic into Chatmail.
◆ Current state
DeltaChat ships frequent versioned desktop releases. Recent work splits across maturing real-time calls, channel/broadcast features, and offloading server-side housekeeping (message deletion, folder fetching) to its Chatmail backend so the email-based app behaves more like a native messenger.
◆ Where it's heading
Two arcs are converging: turning an email-protocol chat client into a full-featured messenger (calls, channels, voice messages) and reducing user-facing email plumbing by letting Chatmail manage it automatically. The product is hiding its email roots behind a cleaner app experience.
◆ Prediction
Expect continued calls refinement and further removal of legacy email-configuration options as Chatmail-managed defaults become the norm; channels/broadcast are the likely next feature focus.
