Postmark adds its own SOC 2 Type 2 report to a run of security work.
A side-by-side editorial comparison of Gromox and Salesmsg — release velocity, themes, recent moves, and the top alternatives to consider.
Gromox 3.13 adds scripts to move Exchange-for-All systems onto it.
Gromox ships a numbered release roughly monthly. 3.13 adds scripts to convert E4A systems to Gromox, full two-way sync of IMAP keywords with MAPI categories, multi-message vCard export and audit logging in emsmdb and zcore, and fixes an EWS gap where any user could answer, alter or move meeting requests in other mailboxes. 3.12 moved MAPI-to-internet conversion onto VMIME with RFC 2231 filenames; 3.11 added IMAP FETCH BINARY and Sent Items copies for send-as and send-on-behalf on shared mailboxes.
Salesmsg's Sherpa AI now sends replies and builds broadcasts on request, with approval first.
Salesmsg's autumn releases have added survey automation, Click Tracking, upgraded Reviews and an official MCP server listed with Claude and ChatGPT. Sherpa AI, the in-app assistant, now acts inside the product: it guides onboarding, replies to conversations and sends messages after user approval, fills in broadcast forms from a description, navigates to any screen and explains 10DLC compliance status.

The project keeps completing Exchange behaviour for clients that expect it, now including shared-mailbox Sent Items and meeting handling that matches Exchange. 3.13's conversion scripts and audit logging point at migration and compliance as the adoption path, alongside the IMAP work that has run since 3.8. Permission checks on EWS calendar operations show the protocol surface now gets security review, not only coverage.
Expect more EWS permission and behaviour corrections and continued IMAP4rev2 coverage; the E4A scripts suggest further migration tooling from other groupware.

Salesmsg is moving from a texting tool with AI features to one operated through an assistant, inside the app via Sherpa and outside it via MCP. Each release ties messaging, automation and CRM data closer to that agent layer.
Expect Sherpa to gain more actions that already exist in the MCP server, such as contact management and campaign reporting, and possibly scheduled or autonomous runs.
