Respond.io
Respond.io is tuning its AI agents for how messaging actually behaves, not how APIs do.
A side-by-side editorial comparison of mailcow and Drift — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Drift now ships inside Salesloft's monthly train, and that train is being pointed at ChatGPT.
Product news for Drift arrives through Salesloft's monthly release notes following the merger, and increasingly through Clari's too. The August notes put the Salesloft MCP server inside ChatGPT as a custom connector while trimming transcript retrieval out of the Claude connector. July was governance work — tiered call-recording visibility and a separate download permission. June added AI adoption metrics to Analytics and Cadence Collections for managing cadence settings in bulk.

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.
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.

Two threads run through the last six months: agentic access to live Salesloft data, gated behind the Agentic add-on, and the permission scaffolding needed to sell that access to security teams. The MCP server launched in April, gained a second client surface in August, and simultaneously lost a tool — the surface is expanding while its scope is being pruned.
Expect the Agentic add-on to keep absorbing the AI feature line, and the transcript-access removal to be followed by explicit per-tool permissions rather than a blanket restore.
