SimpleTexting vs Stalwart: at a glance
What is SimpleTexting?
SimpleTexting's feed is all SMS-marketing blog content — no product releases in this window.
Every recent entry for SimpleTexting is editorial blog content: survey reports on texting behavior, a Gen Z vs. Millennials study, no-show reduction research, unsubscribe data, and how-to guides for clinics and outdated tactics. None describes a change to the texting product itself. This crawl is pulling the company's content marketing, not a changelog.
What is Stalwart?
Stalwart grinds toward standards-complete mail: DKIM2, DMARCbis, and a long JMAP conformance tail.
Stalwart is a self-hosted all-in-one mail and collaboration server (JMAP, IMAP, SMTP/MTA, CalDAV) shipping fortnightly point releases in the 0.16.x line. The work is overwhelmingly protocol conformance and correctness: closing JMAP test-suite gaps, hardening the MTA, and fixing calendar, auth, and cluster edge cases. Recent releases pair one or two standards additions with a dense list of subsystem fixes.

◆ Current state
Every recent entry for SimpleTexting is editorial blog content: survey reports on texting behavior, a Gen Z vs. Millennials study, no-show reduction research, unsubscribe data, and how-to guides for clinics and outdated tactics. None describes a change to the texting product itself. This crawl is pulling the company's content marketing, not a changelog.
◆ Where it's heading
With no product entries in view, the platform's direction can't be assessed from this input. What the content does reveal is a marketing emphasis on data-backed thought leadership — consumer surveys, vertical guides (healthcare, retail) — aimed at demand generation rather than signaling where the product is heading.
◆ Prediction
These entries don't support a product prediction; they indicate where SimpleTexting is pointing its content marketing, not its roadmap.
Stalwart
5.0COMMS
Stalwart grinds toward standards-complete mail: DKIM2, DMARCbis, and a long JMAP conformance tail.
◆ Current state
Stalwart is a self-hosted all-in-one mail and collaboration server (JMAP, IMAP, SMTP/MTA, CalDAV) shipping fortnightly point releases in the 0.16.x line. The work is overwhelmingly protocol conformance and correctness: closing JMAP test-suite gaps, hardening the MTA, and fixing calendar, auth, and cluster edge cases. Recent releases pair one or two standards additions with a dense list of subsystem fixes.
◆ Where it's heading
The direction is depth over breadth — becoming the reference implementation for modern mail standards rather than adding new product surfaces. Over this window it added next-generation email authentication (DKIM2 draft, full DMARCbis suite), Web Push (VAPID/RFC 9749), IDN, FreeBSD support, and OAuth public-client flows, while steadily retiring JMAP conformance bugs. Security and privilege-boundary fixes recur, signaling a maturing codebase being pushed toward production trust.
◆ Prediction
Expect the 0.16.x cadence to continue with more JMAP conformance closeouts and DKIM2/DMARCbis stabilization as those drafts firm up; a 0.17 or 1.0 line would be the signal that the standards backlog has cleared.
