Stalwart vs Trumpia
A side-by-side editorial comparison of Stalwart and Trumpia — release velocity, themes, recent moves, and the top alternatives to consider.
Stalwart vs Trumpia: at a glance
What is Stalwart?
Stalwart is chasing mail RFCs and its own storage layer at the same time
Stalwart ships roughly weekly, and the releases divide cleanly between standards implementation and correctness work. v0.16.18 turns toward resource control — bounds on decompressed inbound DMARC and TLS report size, a cap on RocksDB block-cache memory, column families tuned per access pattern, and a queue scheduler that stops rescanning from the earliest pending event. The preceding releases added IMAP UIDONLY, UIDBATCHES and MESSAGELIMIT, plus JMAP email push and VAPID.
What is Trumpia?
Trumpia publishes SMS explainers weekly and product notes never — including the same post twice.
Ten entries, zero releases. The feed is SMS marketing education: KPIs to track, emoji meanings, what a drip campaign is, why customers opt in, how to switch RCS back to SMS, and an award mention. The KPI post appears twice within a week under the same title with near-identical copy, so the feed is duplicating its own content as well as carrying none from the product. Nothing here reveals what Trumpia has shipped.

◆ Current state
Stalwart ships roughly weekly, and the releases divide cleanly between standards implementation and correctness work. v0.16.18 turns toward resource control — bounds on decompressed inbound DMARC and TLS report size, a cap on RocksDB block-cache memory, column families tuned per access pattern, and a queue scheduler that stops rescanning from the earliest pending event. The preceding releases added IMAP UIDONLY, UIDBATCHES and MESSAGELIMIT, plus JMAP email push and VAPID.
◆ Where it's heading
Two threads run through every release. One is RFC coverage across IMAP, JMAP, CalDAV and WebDAV, implemented close to the specification including drafts. The other is a long tail of protocol-conformance fixes, many of them cases where JMAP and IMAP disagreed about the same state. The newest release adds a third: memory and scheduling limits, which is what a server codebase starts doing when deployments get large enough for defaults to hurt.
◆ Prediction
Expect continued RFC additions across the JMAP and IMAP surfaces, with more of the storage-tuning work that v0.16.18 started as RocksDB deployments scale.
Trumpia
5.0COMMS
Trumpia publishes SMS explainers weekly and product notes never — including the same post twice.
◆ Current state
Ten entries, zero releases. The feed is SMS marketing education: KPIs to track, emoji meanings, what a drip campaign is, why customers opt in, how to switch RCS back to SMS, and an award mention. The KPI post appears twice within a week under the same title with near-identical copy, so the feed is duplicating its own content as well as carrying none from the product. Nothing here reveals what Trumpia has shipped.
◆ Where it's heading
The consistent thread is defending SMS against RCS: the guide explaining how to turn RCS off frames plain SMS as the reliable, universally supported channel, and the rest of the content keeps attention on fundamentals a Trumpia customer already buys into. That is a retention posture rather than a product one. With no release notes in the window, there is no evidence of the product itself moving in any direction.
◆ Prediction
These entries support no prediction about the product — the feed carries marketing content only, so a real release would have to appear on a different channel before anything could be said about direction.
