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 Omnisend?

Omnisend is quietly rebuilding itself around the agencies that run its stores.

Omnisend remains an ecommerce email and SMS automation platform, but the visible work has shifted to the Partner Portal: templated accounts, access management, and workflow copying across accounts. Alongside that, segmentation gained Total Spent and AOV filters, and a Blotout EdgeTag integration adds server-side event capture for automations that browser pixels miss. The core campaign builder is stable; the surrounding operator layer is where the changes are landing.

◆ 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.

Omnisend is quietly rebuilding itself around the agencies that run its stores.

◆ Current state

Omnisend remains an ecommerce email and SMS automation platform, but the visible work has shifted to the Partner Portal: templated accounts, access management, and workflow copying across accounts. Alongside that, segmentation gained Total Spent and AOV filters, and a Blotout EdgeTag integration adds server-side event capture for automations that browser pixels miss. The core campaign builder is stable; the surrounding operator layer is where the changes are landing.

◆ Where it's heading

The Partner Portal releases stack into a coherent argument: build once, replicate across client stores. Templated accounts, cross-account workflow copying, and per-member access control are the three pieces an agency needs to run dozens of merchants without rebuilding each one. Read together, Omnisend is moving from a single-store SMB tool toward a platform operated on behalf of merchants rather than by them.

◆ Prediction

Expect the agency layer to keep filling in — cross-client reporting or billing roll-ups are the obvious gaps once templating and access control exist. The segmentation and tracking work suggests a parallel push on data fidelity, but the entries don't yet show which of the two gets priority.
