You cross someone's life's work on your way to work.
A bridge, a railway. Someone refused to give up to make it real. You probably don't know their name.
We made a film about that. It gets from two bike mechanics to the moon, then a newsletter about solar panels.
Sound on.
The next impossible things are being written in code. A lot of that is happening in Cursor.
Today we're launching the official Nitrosend plugin on the Cursor Marketplace.
And we do the email.

“Soon there will be 100 Billion agents.”
I think it undershot this by a factor of 10.
There are 8 billion people on earth. Soon there'll be 100 billion AI agents. Every one of them needs email.
Six weeks ago I said the next wave of teams would run email through an agent instead of a dashboard. Today it ships.
@nitrosendx is launching Agentic Email Marketing: the email layer for the agent economy.
What agents can do on Nitrosend right now:
Sign themselves up. Point any agent at nitrosend.com/SKILL.md and it creates the account, connects your domain, sorts billing and sends its first email. No API key. No dashboard. No human required. Shipped, and users agents signing up with it daily.
Get their own inboxes (beta, by request). Real addresses on the domain you own. Your agents receive, and send 1-1 email conversations with customers. A reply lands at 3am, your agent answers it. Anything that needs a human gets escalated to you. Ask us and we'll flick yours on.
Next: Agentic Outreach (coming soon). Your agent studies your best customers, finds more like them, writes like a person, sends in sequence and works the replies.
Then: set a goal and walk away. Goal-based agentic marketing is in development. "20% more activations this quarter" and Nitrosend plans, sends, measures and improves every week.
Why we built this: Gmail is agent hostile and expensive per seat. Legacy email platforms assume a human sitting in a dashboard. agents needed an email layer of their own.
They're already better at it than we are. They read everything, never miss a follow-up, and write personally at any scale. *94%* of actions on Nitrosend already happen inside an agent (Claude, Codex, ChatGPT, Cursor), not in our UI.
Humans approve. Agents operate.
This is our third email company. Six billion emails across the first two. We've been burned by every ugly part of email already, which is why the approval gates are built in exactly where you want them.
Watch the launch, then send your agent to work:
nitrosend.com/email-for-agen…
send it.

Love it when our users volunteer new ways to run Nitrosend that I haven't even used yet.
"It’s been an amazing experience via Grok Bot and how the MCP has made email so much easier."
Building an agent first tool is wild.

Two weeks since Nitrosend for agencies went live, and feedback has been amazing.
One salon marketing platform joined and added five client salons through the partner flow already. Their agent ran the setup, the salons own their accounts. nitrosend.com/agencies
Nitrosend for agencies and platforms is live.
Run every client's email from one AI conversation. Build the flows, copy what works to the next client, then hand over the keys.
Your agent does the setup. You approve what ships.

Try it with one client.
We've put the film and five client prompts on the agencies page: scan the brand, build the welcome flow, copy the setup, switch clients, migrate from your old ESP.
Use the prompts. Tell us what needs work.

One brief.
Two models.
24 emails about the agent economy that Stripe is literally building.
The full film and full prompt below.
We were at Stripe Day last week. Then yesterday they shipped a CLI for agents to spend money.
Our @nitrosendx Stripe 2031 experiment: one brief, two models, 12 emails.
Left: Claude Fable 5.
Right: Codex 5.6 Sol.
Codex went darker. Fable went bigger.
