OneSignal's feed is all blog: RCS-vs-SMS explainers and buyer-guide SEO, no product news
A side-by-side editorial comparison of Flodesk and Litmus — release velocity, themes, recent moves, and the top alternatives to consider.
Flodesk fills in the feature gaps, maturing from a design-first tool into a fuller email-and-commerce platform
Flodesk is shipping a steady stream of capability and UX additions that close gaps against more established email marketing tools: subject-line A/B testing, a calendar planning view, reversible subscriber archiving, workflow email expiration, and an inline list view with metrics. Alongside, commerce features (Stripe Tax/VAT, checkout) and integrations (Google Analytics, Canva) round out the platform.
Litmus keeps publishing deliverability and email-craft guidance, not product releases.
The crawled feed is entirely Litmus's marketing blog: deliverability explainers (Microsoft SNDS, spam placement), email-craft pieces, and event coverage. None of it describes a change to the Litmus product itself.

The arc is feature maturation. Flodesk built its brand on simplicity and design, and is now adding the optimization, planning, and list-management tooling that power users expect — without abandoning its low-friction, built-into-the-flow design ethos. The parallel commerce investment suggests it wants to be a creator's send-and-sell platform, not just an email builder.
Expect continued parity features (deeper analytics on the A/B and calendar tooling) and more commerce depth around checkout and Stripe. Each release is incremental, so the likely next moves are extensions of existing surfaces rather than a new direction.

Content is leaning hard into deliverability and the AI-era inbox — how mailbox providers filter, how GenAI cuts both ways for senders. That signals where Litmus wants to be seen as an authority, but it is editorial output, not shipped capability.
We can't forecast product moves from a blog feed; expect continued deliverability and AI-in-email content unless the crawl source is pointed at an actual changelog.
