What is Salesmsg?

Salesmsg is turning a texting inbox into an AI agent that also answers the phone.

Salesmsg ships weekly against three tracks: AI agents that hold conversations and take actions, a voice layer that now includes queues, IVR, and simultaneous inbound calls, and deep write-access into HubSpot and Salesforce. Agent work has moved past prompt-writing — agents are built by chatting, tested live before launch, run off live data sources, and book meetings directly into a CRM over SMS. The July release adds per-workflow credit accounting, which is the first sign the company is treating agent spend as something customers need to audit.

What is mailcow?

Six releases, and every one of them is a security update in some form.

mailcow ships on a monthly tag with lettered revisions, and this window contains no release that isn't security-driven. The May line ran to three revisions in two weeks — an unnamed fix with a CVE identifier withheld until later, SOGo 5.12.8 covering four upstream issues, an unbound CVE, HTML escaping added to the quarantine table, sieve filter editor and queue manager. July brought Rspamd 4.1.0 and later 4.1.4, nginx 1.30.3 and a CVE fix, Postfix moved off bookworm, and a release described only as hardening.

Salesmsg vs mailcow: editorial side-by-side

S6.3

Salesmsg is turning a texting inbox into an AI agent that also answers the phone.

◆ Current state

Salesmsg ships weekly against three tracks: AI agents that hold conversations and take actions, a voice layer that now includes queues, IVR, and simultaneous inbound calls, and deep write-access into HubSpot and Salesforce. Agent work has moved past prompt-writing — agents are built by chatting, tested live before launch, run off live data sources, and book meetings directly into a CRM over SMS. The July release adds per-workflow credit accounting, which is the first sign the company is treating agent spend as something customers need to audit.

◆ Where it's heading

The product is consolidating from a set of channels into a single automated front desk: text, call, route, book, and now collect the review afterward. Each CRM release moves work from the human to the agent — enrollment from Salesforce Flows, reschedules handled over text, call outcomes logged without a manual save. The newest release pushes past conversations entirely into reputation, which is the standard expansion path for SMB messaging platforms and puts Salesmsg on the same ground as the review-and-messaging suites rather than pure SMS tools.

◆ Prediction

Expect the review product to be wired into agents and workflows next — automatic review requests triggered by a closed conversation or a completed booking — and further credit and permission controls as agent usage grows. The Salesforce and HubSpot tracks look set to continue on a quarterly bundle cadence.

5.0

Six releases, and every one of them is a security update in some form.

◆ Current state

mailcow ships on a monthly tag with lettered revisions, and this window contains no release that isn't security-driven. The May line ran to three revisions in two weeks — an unnamed fix with a CVE identifier withheld until later, SOGo 5.12.8 covering four upstream issues, an unbound CVE, HTML escaping added to the quarantine table, sieve filter editor and queue manager. July brought Rspamd 4.1.0 and later 4.1.4, nginx 1.30.3 and a CVE fix, Postfix moved off bookworm, and a release described only as hardening.

◆ Where it's heading

Two distinct pressures are visible. One is upstream: mailcow bundles Postfix, Rspamd, SOGo, nginx, unbound and Dovecot, so every one of their advisories becomes a mailcow release, and the base image migration from bookworm to trixie is that same maintenance surfacing at the OS layer. The other is the project's own web UI, where output escaping is being retrofitted view by view — quarantine table, sieve editor, queue manager, quarantine overview — which reads as a systematic pass rather than isolated reports. Earlier releases in the feed show where feature work went when it happened: forced 2FA, ACME DNS-01 challenges, and admin controls over EAS and DAV access.

◆ Prediction

Expect the monthly-plus-revisions rhythm to continue with upstream component bumps driving most of it, and the web UI escaping pass to reach the remaining admin views.
