What is OneSignal?
OneSignal's feed is all blog: RCS-vs-SMS explainers and buyer-guide SEO, no product news
This is a marketing/SEO blog feed, not a changelog. Every entry is thought-leadership or a buyer's-guide listicle (audits, checklists, 'complete guide' posts) with only a sentence or two of body text. There are no shipped features, version notes, or capability changes to classify. A recurring editorial theme is the SMS-to-RCS shift, but it is discussed as commentary, not announced as a OneSignal release.
What is Customer.io?
Design Studio becomes the one surface where every Customer.io message is built
Customer.io is consolidating message creation around Design Studio, its newer visual editor, and steadily retiring the classic drag-and-drop path. Recent releases add global styling, brand variants, an email review/readiness panel, and a no-code notification inbox — all authored in the same place. The in-app messaging surface is also maturing, now with dark-mode-aware styling across web, iOS, and Android.

OneSignal's feed is all blog: RCS-vs-SMS explainers and buyer-guide SEO, no product news
◆ Current state
This is a marketing/SEO blog feed, not a changelog. Every entry is thought-leadership or a buyer's-guide listicle (audits, checklists, 'complete guide' posts) with only a sentence or two of body text. There are no shipped features, version notes, or capability changes to classify. A recurring editorial theme is the SMS-to-RCS shift, but it is discussed as commentary, not announced as a OneSignal release.
◆ Where it's heading
The content cadence points OneSignal's messaging toward multi-channel positioning (push plus SMS/RCS, reaching app-less users), which signals where marketing wants to steer buyers rather than any change to the product surface itself.
◆ Prediction
Given the entries are uniformly blog content, expect more RCS/SMS and 'how to choose a provider' pieces; nothing here supports a prediction about an actual product release.

Design Studio becomes the one surface where every Customer.io message is built
◆ Current state
Customer.io is consolidating message creation around Design Studio, its newer visual editor, and steadily retiring the classic drag-and-drop path. Recent releases add global styling, brand variants, an email review/readiness panel, and a no-code notification inbox — all authored in the same place. The in-app messaging surface is also maturing, now with dark-mode-aware styling across web, iOS, and Android.
◆ Where it's heading
The clear direction is Design Studio as the single composition layer for email, in-app, and inbox, with migration tooling to pull legacy content forward and quality gates (SpamAssassin scoring, link/image validation) built in. In parallel, Customer.io is threading its AI Agent and Salesforce sync templates into setup flows to cut configuration work. Expect fewer standalone editors and more capability folded into Design Studio.
◆ Prediction
Next moves likely deepen Design Studio: broader global-component reuse and further deprecation of the classic editor, plus more Agent-assisted authoring beyond Salesforce field mapping.
