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 lets publishers store their own member details in custom fields.

Ghost now lets publications define custom fields and store member details directly in Ghost. It follows a run of member email automation releases: tier-specific welcome sequences and automation analytics in October, then lifecycle triggers on 4 November that start flows when a paid member changes tier or leaves.

◆ 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 lets publishers store their own member details in custom fields.

◆ Current state

Ghost now lets publications define custom fields and store member details directly in Ghost. It follows a run of member email automation releases: tier-specific welcome sequences and automation analytics in October, then lifecycle triggers on 4 November that start flows when a paid member changes tier or leaves.

◆ Where it's heading

Ghost is building out its member database so automations have more to act on. Custom fields are the data layer the triggers and sequences have been missing, which points toward segmenting and targeting by publisher-defined attributes.

◆ Prediction

Expect automations or email segments to filter on custom fields next; the entry does not say whether fields can be set through signup forms or the API.
