Day 0, 10:00 — your agent sends a demo follow-up. Day 2, 14:37 — the prospect replies with a question. Day 2, 14:39 — they send a second thought. Day 5 — silence, then a reply to something the agent said a week ago. Somewhere between day 0 and day 5, your process restarted twice and deployed once. A single send-and-forget email is easy. The timeline above is the actual job: a conversation spanning five exchanges over days, where the agent has to remember what it said, what it's waiting for, and where in the workflow it stands — across restarts, deploys, and hours of dead air. The multi-turn conversation recipe builds this loop on a Nylas Agent Account (the feature's in beta), running entirely on webhooks and the Threads API — no polling, no missed messages. State lives outside the model The core design decision: every active conversation gets a durable record keyed by the thread ID. const conversationRecord = { threadId : " nylas-thread-id " , grantId : AGENT_GRANT_ID , contactEmail : " prospect@example.com " , purpose : " demo_followup " , // What started this conversation step : " awaiting_reply " , // Where in the workflow we are turnCount : 1 , maxTurns : 10 , // Safety cap before escalation lastActivityAt : " 2026-04-14T10:00:00Z " , metadata : {}, }; The step field is the heart of it — a tiny state machine tracking what the agent is waiting for, which determines how the next inbound message gets handled. The store has to be durable (Postgres, Redis with AOF, DynamoDB); the gap between messages can be days, so in-memory state is a non-starter. Starting a conversation means sending the first message and persisting the record under the threadId the send returns: async function startConversation ({ to , subject , body , purpose , metadata }) { const sent = await nylas . messages . send ({ identifier : AGENT_GRANT_ID , requestBody : { to : [{ email : to . email , name : to . name }], subject , body , }, }); await db . conversations . create ({ threadId : sent . dat

Gaming handhelds are amazing. They make it so much easier to fit all kinds of games into my day. Sadly, they’re less affordable than they’ve ever been — due to an unprecedented, AI-fueled shortage of memory chips, an unforced oil crisis, rampant inflation, fallout from tariffs, and more. But that’s not going to stop you. […]

Even with the looming specter of rising prices, there's never been a better time for portable gaming. The Steam Deck has ushered in a new era of handheld PCs, the Analogue Pocket and other Game Boy-style remakes are making retro games more approachable than ever, the Playdate has led to an alternate universe of weirdo […]

The sun is out, the sky is clear. It’s time to get outside and disconnect — from work, at least. This summer, we’re looking at all the ways to upgrade our free time indoors and out, from smart lights for the backyard to great gadgets to bring camping to ways to wind down at the local library.

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. Why “reprogramming” is the buzziest approach to reversing aging right now Earlier this week, Life Biosciences, a biotech company focused on reversing age-related diseases, announced that it had dosed its first…

Let no one accuse Bernie Sanders of ducking the big questions. Writing in the New York Times last week, the senator asked : “Will the future of humanity be determined by a handful of billionaires who have promoted and developed AI, with virtually no democratic input, who stand to become even richer and more powerful than they are today?” We agree entirely that this is one of the most potent questions facing global democracy today. Our book, Rewiring Democracy , surveys the emerging uses for and impacts of AI in democracy around the world and reaches the same conclusion: that the most urgent risk posed by AI is the ...
