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 MailPoet?

MailPoet's feed is near-dormant: one 2026 post, and it's about consent-gating open tracking.

This feed has almost stopped. Six of the last ten entries predate 2025, and the only substantive recent activity is a July 2026 post on French and Italian regulators deciding that email open-tracking pixels require consent — which notes MailPoet now ships controls for it. Apart from an April 2026 review-request explainer, there is no visible release cadence to read.

◆ 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.

MailPoet's feed is near-dormant: one 2026 post, and it's about consent-gating open tracking.

◆ Current state

This feed has almost stopped. Six of the last ten entries predate 2025, and the only substantive recent activity is a July 2026 post on French and Italian regulators deciding that email open-tracking pixels require consent — which notes MailPoet now ships controls for it. Apart from an April 2026 review-request explainer, there is no visible release cadence to read.

◆ Where it's heading

What signal exists points at compliance rather than product ambition: sender-requirement explainers in 2024, tracking-pixel consent controls in 2026. The older entries show a product that once announced features here — custom automation triggers, segmentation, automation analytics — but that stream stopped years ago. Whether development continues on another surface is not something this feed can answer.

◆ Prediction

There is not enough recent activity to forecast a next move; one product-relevant post in over a year cannot support a prediction. If consent-gated open tracking spreads past France and Italy, more compliance controls are the likeliest thing to appear.
