Fellow vs Salesmsg
A side-by-side editorial comparison of Fellow and Salesmsg — release velocity, themes, recent moves, and the top alternatives to consider.
Fellow vs Salesmsg: at a glance
What is Fellow?
Fellow's public changelog has been silent since 2021 — no recent direction is observable here.
The visible signal stops in spring 2021. The last few releases were calendar-extension touch-ups: action items appearing directly in the Google Calendar extension, public view-only meeting links for external attendees, and multi-calendar sync within a single Google or Office account. Nothing in this dataset reflects the past several years of Fellow's actual work.
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.

Fellow
0.0COMMS
Fellow's public changelog has been silent since 2021 — no recent direction is observable here.
◆ Current state
The visible signal stops in spring 2021. The last few releases were calendar-extension touch-ups: action items appearing directly in the Google Calendar extension, public view-only meeting links for external attendees, and multi-calendar sync within a single Google or Office account. Nothing in this dataset reflects the past several years of Fellow's actual work.
◆ Where it's heading
From the entries alone, no current trajectory can be inferred — the data is years stale. Whether Fellow has shifted to AI-meeting-notes or remained focused on the original meeting-management surface is not visible here and would be guesswork to assert.
◆ Prediction
Predictions can't be grounded in this data. The most useful next step is to refresh Fellow's changelog source so that present-day moves are captured.
Salesmsg
6.3COMMS
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.
