What is SimpleTexting?

SimpleTexting publishes original SMS survey data on a schedule, and no release notes at all.

The feed carries comparison listicles, buyer-intent roundups, and original survey research — 1,200+ patients on appointment reminders, generational messaging preferences, unsubscribe drivers, and a 2026 texting statistics report. The newest entry positions the product against Twilio for buyers who do not want to build an SMS platform themselves. No entry in the window describes a product change.

What is Stalwart?

Stalwart adds full SCIM v2 provisioning and 24-language calendar support as its standards coverage extends further than most commercial mail servers.

Stalwart is maintaining a weekly-or-faster release cadence, with alternating feature releases and dense bug-fix releases. The v0.16.20 release landed full SCIM v2 (Enterprise) including cursor-based pagination and the IPSIE lifecycle profile, conference links in calendar invites, and 24 new calendar interface translations. Below the feature line, the project is steadily closing correctness gaps across JMAP, CalDAV, IMAP, and MTA — many of them edge-case RFC compliance issues.

SimpleTexting vs Stalwart: editorial side-by-side

S5.0

SimpleTexting publishes original SMS survey data on a schedule, and no release notes at all.

◆ Current state

The feed carries comparison listicles, buyer-intent roundups, and original survey research — 1,200+ patients on appointment reminders, generational messaging preferences, unsubscribe drivers, and a 2026 texting statistics report. The newest entry positions the product against Twilio for buyers who do not want to build an SMS platform themselves. No entry in the window describes a product change.

◆ Where it's heading

This is a content and SEO channel, not a changelog, and it has been consistent about it across the full window. The recurring investment is in first-party survey data rather than competitor-comparison filler, which is the more durable of the two plays, and the Twilio-alternative framing shows where the company thinks its buyers come from: teams choosing a finished product over an API they would have to assemble.

◆ Prediction

Expect the survey-and-report cadence to continue and more head-to-head comparison pages against API-first competitors. Nothing in this feed indicates what is happening in the product itself.

S6.3

Stalwart adds full SCIM v2 provisioning and 24-language calendar support as its standards coverage extends further than most commercial mail servers.

◆ Current state

Stalwart is maintaining a weekly-or-faster release cadence, with alternating feature releases and dense bug-fix releases. The v0.16.20 release landed full SCIM v2 (Enterprise) including cursor-based pagination and the IPSIE lifecycle profile, conference links in calendar invites, and 24 new calendar interface translations. Below the feature line, the project is steadily closing correctness gaps across JMAP, CalDAV, IMAP, and MTA — many of them edge-case RFC compliance issues.

◆ Where it's heading

Stalwart is building toward parity with commercial enterprise mail servers on identity federation and provisioning (SCIM v2, VAPID for web push, DMARCbis/DKIM2 already landed). The pace of RFC implementation is unusually aggressive for an open-source project; the combination of JMAP, CalDAV, IMAP UIDONLY/UIDBATCHES, and SCIM v2 positions it as a viable self-hosted alternative for organizations that need standards compliance without vendor lock-in.

◆ Prediction

WebAuthn/passkey-based authentication and improved multi-tenant administration tooling are the most likely next capability additions, given the current trajectory toward enterprise identity management.
