Salesmsg vs Signal: at a glance
What is Salesmsg?
Salesmsg adds call-back requests and a one-click Emergency Stop for all outbound texts.
Salesmsg's autumn releases added survey automation, Click Tracking, upgraded Reviews and an official MCP server, then turned Sherpa AI into an assistant that sends replies and builds broadcasts after approval. The November 12 update moves to calling and safety controls: callers can request a callback instead of holding, Emergency Stop pauses every outbound message at once, inboxes can require call recording, tags can be applied during calls with HubSpot sync, and a weekly recap reports AI agent performance.
What is Signal?
Signal brings Secure Backups to every platform and starts automating key verification.
Signal Secure Backups improvements are now available on all platforms with iOS 8.30, a year after the feature's introduction. Android 8.20 and iOS 8.22 extended linked devices to Android phones, Android tablets and iPhones. Automatic key verification now complements safety numbers as a simpler way to confirm no unexpected party sits in a session.

Salesmsg adds call-back requests and a one-click Emergency Stop for all outbound texts.
◆ Current state
Salesmsg's autumn releases added survey automation, Click Tracking, upgraded Reviews and an official MCP server, then turned Sherpa AI into an assistant that sends replies and builds broadcasts after approval. The November 12 update moves to calling and safety controls: callers can request a callback instead of holding, Emergency Stop pauses every outbound message at once, inboxes can require call recording, tags can be applied during calls with HubSpot sync, and a weekly recap reports AI agent performance.
◆ Where it's heading
With AI now able to send messages, Salesmsg is adding the brakes: an organization-wide stop switch and weekly reports on what its AI agents did. Calling features keep catching up with texting, with queue callbacks and recording rules.
◆ Prediction
Expect more controls over what Sherpa and AI agents may send, such as per-agent limits or approval rules, alongside further HubSpot call-data sync.
Signal
0.0COMMS
Signal brings Secure Backups to every platform and starts automating key verification.
◆ Current state
Signal Secure Backups improvements are now available on all platforms with iOS 8.30, a year after the feature's introduction. Android 8.20 and iOS 8.22 extended linked devices to Android phones, Android tablets and iPhones. Automatic key verification now complements safety numbers as a simpler way to confirm no unexpected party sits in a session.
◆ Where it's heading
The earlier alternation between protocol work and feature catch-up has narrowed into one theme: making multi-device life safe without asking users to do anything difficult. Backups, linked devices and automatic verification each remove a manual step or a reason to leave.
◆ Prediction
The entries are teasers and do not point to a specific next feature. Further multi-device polish looks most likely, since that is where the last three posts landed.
