Stalwart
Stalwart is shipping email's next-generation auth stack while the specs are still in draft.
A side-by-side editorial comparison of Beeper and Heymarket — release velocity, themes, recent moves, and the top alternatives to consider.
Beeper stopped aggregating apps and started merging the people inside them.
The bridge count keeps climbing, with LINE the most recent addition, but the more consequential work is identity-level. Merge Chats collapses conversations with the same person across multiple networks into a single thread. Around that sits a long run of parity work — group chat creation, delete chat, disappearing messages, message requests — closing the gaps that forced users back into native clients.
Real features ship between the SEO posts: tags, webhooks, escalations, and now RCS via Twilio.
Heymarket's feed is a marketing blog with product announcements mixed in at roughly one post in three. The genuine releases in this window are Escalations, which pushes an unanswered conversation to a named person, and enablement for RCS campaigns through Twilio. The rest — a conversational-AI definition, a healthcare AI buying guide, email-writing advice — is search content with no product change behind it.

Around that sits a long run of parity work — group chat creation, delete chat, disappearing messages, message requests — closing the gaps that forced users back into native clients.
Two tracks run in parallel. Parity work is making Beeper safe to use as the only client, and for the major networks it is close to finished. On top of that, the product is starting to add things no native app can do: cross-network chat merging, in-chat AI models, a unified requests folder. The public call for third-party bridges suggests network coverage is increasingly a community responsibility rather than an in-house roadmap item.
With conversations merged across networks, unified contacts and cross-network search are the natural follow-ons — the organizing primitive shifts from the chat to the person.

The product work visible here is all about absorbing volume: tags to structure conversations, inbound webhooks to pull in the rest of the stack, escalations to catch what nobody answered, and AI agents the team says it trained against its own inbox first. Heymarket is building the operations layer around business messaging rather than extending the messaging surface itself. Channel breadth is arriving through partners, with RCS riding Twilio rather than native carrier work.
The next release is most likely another triage or routing control, since escalations and conversation tags both point that way. Entry bodies in this feed are truncated excerpts, so how far the AI agent work has actually gone is not visible here.
