What is Customer.io?

Customer.io spent the summer pushing messaging off the screen and into location, time, and the lock screen

The summer release cycle put more than ten features into the product, and the coherent ones are about context rather than content: geofences trigger workflows when someone enters or leaves a physical location, live notifications render as iOS Live Activities and Android Live Updates, date triggers now read attributes on custom objects, and a notification inbox retains pushes. Around that sits infrastructure work — SMS via Sinch, Infobip and Vonage, multiple mobile apps per platform in one workspace, send-rate controls on automations — and an LLM actions surface where knowledge sources can be attached once and reused across prompts. The most recent entry is editor ergonomics in Design Studio.

What is Ghost?

Ghost is quietly turning its newsletter into a lifecycle marketing engine.

Ghost's last quarter of releases is almost entirely membership and money: gift subscriptions, publisher gift links, comment threading, saved member views, and now automated email sequences with their own analytics. The publishing and theming side still gets attention, with in-browser theme editing and a staff admin toolbar, but it is no longer where the work concentrates. The product a Ghost operator touches daily is increasingly a subscriber CRM with a CMS attached.

◆ Current state

The summer release cycle put more than ten features into the product, and the coherent ones are about context rather than content: geofences trigger workflows when someone enters or leaves a physical location, live notifications render as iOS Live Activities and Android Live Updates, date triggers now read attributes on custom objects, and a notification inbox retains pushes. Around that sits infrastructure work — SMS via Sinch, Infobip and Vonage, multiple mobile apps per platform in one workspace, send-rate controls on automations — and an LLM actions surface where knowledge sources can be attached once and reused across prompts. The most recent entry is editor ergonomics in Design Studio.

◆ Where it's heading

The platform is expanding the set of things that can start a message and the set of places one can land, which is a different axis from the segmentation-and-copy tooling most of this category competes on. Geofences and live notifications both take work that previously required a specialist vendor or custom device code and make it a workflow primitive. The LLM actions work is following the same instinct — reusable knowledge sources are the beginning of prompt infrastructure rather than a prompt box — but it is the least developed of the threads. Meanwhile send-rate control and multi-app support read as enterprise deployment blockers being cleared.

◆ Prediction

Expect the location and live notification surfaces to gain the operational controls that continuous device features require, and the LLM actions path to keep accreting reusable pieces. Design Studio is receiving steady editor polish, so a broader component authoring release is plausible.

Ghost is quietly turning its newsletter into a lifecycle marketing engine.

◆ Current state

Ghost's last quarter of releases is almost entirely membership and money: gift subscriptions, publisher gift links, comment threading, saved member views, and now automated email sequences with their own analytics. The publishing and theming side still gets attention, with in-browser theme editing and a staff admin toolbar, but it is no longer where the work concentrates. The product a Ghost operator touches daily is increasingly a subscriber CRM with a CMS attached.

◆ Where it's heading

Each release adds another piece of the paid-newsletter stack that operators currently leave Ghost to get: drip onboarding, referral loops through gifting, self-updating audience segments, and per-sequence performance data. The pattern is closing the gap with dedicated newsletter platforms rather than deepening the CMS. Distribution work runs as a second thread, with social profile connections and AI-search metadata aimed at making sure the audience arrives at all.

◆ Prediction

Expect sequences to leave beta with segment-triggered or branching sends, since Ghost has now shipped both self-updating member filters and sequence analytics, the two inputs a targeted automation needs.
