Delta Chat vs Salesmsg
A side-by-side editorial comparison of Delta Chat and Salesmsg — release velocity, themes, recent moves, and the top alternatives to consider.
Delta Chat vs Salesmsg: at a glance
What is Delta Chat?
DeltaChat keeps shedding its email-client past to become a full messenger.
DeltaChat's desktop client is steadily converting from an email-based chat tool into a full-featured messenger. Recent releases layer on calls, channels, mini-apps, multi-transport, and proxies while stripping out legacy email affordances like OAuth and manual folder handling. The result is a client that increasingly hides its email plumbing behind mainstream-messenger conventions.
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.
Delta Chat vs Salesmsg: editorial side-by-side
Delta Chat
2.5COMMS
DeltaChat keeps shedding its email-client past to become a full messenger.
◆ Current state
DeltaChat's desktop client is steadily converting from an email-based chat tool into a full-featured messenger. Recent releases layer on calls, channels, mini-apps, multi-transport, and proxies while stripping out legacy email affordances like OAuth and manual folder handling. The result is a client that increasingly hides its email plumbing behind mainstream-messenger conventions.
◆ Where it's heading
The direction is consistent: lean on the chatmail relay model, remove classic-email options release by release, and match the UX users expect from Signal or Telegram. Recent versions add a command palette, message multiselect, keyboard navigation, and proxy status while deleting server-fetch and Show-Email settings. Each release trades another email-era affordance for a messenger-parity feature.
◆ Prediction
Expect continued removal of email-era settings and more messenger-parity work — likely deeper call and channel tooling plus command-palette expansion — rather than any return to email-client framing.
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.
