Delta Chat
DeltaChat keeps shedding its email-client past to become a full messenger.
A side-by-side editorial comparison of SlickText and Threema — release velocity, themes, recent moves, and the top alternatives to consider.
SlickText adds RCS, pushing past plain SMS into verified, branded business messaging.
SlickText runs a heavy SEO content engine — templates, listicles, vertical guides, awards posts — but the substantive product move is the addition of basic RCS messaging, bringing verified business identity and richer formatting to a platform built on plain SMS. Everything else in the recent feed is marketing and category positioning.
Threema's feed is mostly privacy-positioning essays, with a thin layer of real Threema Work admin features underneath.
Threema's changelog is really a blog: most entries are privacy commentary and positioning — why it will not implement WhatsApp interoperability under the DMA, system-level anonymity as the ultimate protection, World Emoji Day musings. The genuine product news is sparse and concentrated in Threema Work, the business tier: tag management in the Management Cockpit and an availability-status feature. The signal-to-marketing ratio is low.
SlickText runs a heavy SEO content engine — templates, listicles, vertical guides, awards posts — but the substantive product move is the addition of basic RCS messaging, bringing verified business identity and richer formatting to a platform built on plain SMS. Everything else in the recent feed is marketing and category positioning.
The product is broadening from SMS-only toward a multi-format messaging stack where channel trust and branding matter. RCS gives SlickText a credible answer to the deliverability and impersonation problems that plain text marketing can't solve on its own, and slots it against enterprise rivals it keeps writing comparison content about.
Expect RCS to move from 'basic' to feature-complete — branded sender profiles, rich cards, and read receipts — and to become a headline differentiator in the comparison content SlickText already publishes against Attentive and EZ Texting.
Threema's changelog is really a blog: most entries are privacy commentary and positioning — why it will not implement WhatsApp interoperability under the DMA, system-level anonymity as the ultimate protection, World Emoji Day musings. The genuine product news is sparse and concentrated in Threema Work, the business tier: tag management in the Management Cockpit and an availability-status feature. The signal-to-marketing ratio is low.
The editorial line is consistent and deliberate: Threema is doubling down on privacy maximalism as its identity, explicitly rejecting interoperability that would compromise data privacy and framing anonymity as an architectural property rather than a feature. Actual shipping is incremental and centered on Threema Work's admin ergonomics.
Expect continued privacy-first positioning pieces and steady, small Threema Work improvements; the 'What We're Working On' post hints at more of the same rather than a directional shift.
