Set up email for sellers and buyers in one prompt.
Draft six flows for sellers, buyers and sponsors in Claude or ChatGPT, then review them before they go live.
Use Nitrosend to set up the email basics for my platform:
Read https://nitrosend.com/skills/marketplaces.md and follow it step by step.
1. Connect Nitrosend.
2. Check what I already send, then build what is missing as drafts: seller onboarding, a no-sale nudge, buyer activation, order notices, review requests and a sponsor reply.
3. Send me a test of every email. Put backend changes in one pull request.
4. Ask me before anything goes live, before you change DNS and before you import contacts.Paste it into Claude, ChatGPT, Cursor or Codex.On your phone? Email it to yourself

How to run it.
- 1
Copy the prompt
Paste it into Claude or ChatGPT. Your agent reads your platform first and asks only what it cannot find.
- 2
See your flows built
It confirms the plan in one message, then builds all six flows as drafts, labeled by side.
- 3
Review, test, go live
Your agent tests every email, puts backend changes in one pull request, or a spec for your developer, and switches on only what you approve.
Set up with Nitrosend
Your agent connects Nitrosend, makes a list for each side, and wires up the events your payments provider and backend already emit, so each one starts the right flow.
Start free Free to start: 5,000 emails up front, then 500 free every month. No card needed.
- Seller, buyer and sponsor flows run in one account, each started by its own events
- Members can get their own client-owned Nitrosend account, created from the Clients page or the Partner API
- Unlimited contacts. You pay for what you send
What your agent reads.
The skill is a plain text file you can read before you run it.
Read the skill file- One message to confirm the plan and the events to connect
- Six flows, labeled by side, with timings and the job of every email
- A test of every email, event call and link
- A go-live checklist: your sending domains, consent and your yes
The numbers to measure against.
The plan on this page comes from the Email Marketing Bible, the open-source email skill we maintain: 908 sources, 49 practitioners and 19 industry playbooks. Nobody publishes a large benchmark for two-sided platforms, so these are the general numbers to beat. Read the Email Marketing Bible.

Trigger onboarding on what a person has done, never on the date they signed up.

From the co-founders of Bluethumb.
We’ve run a two-sided marketplace. George and Ed co-founded Bluethumb, an Australian online art marketplace where artists sell directly to collectors. A daily email recommending art from what each buyer had liked and added to cart came to drive about 10% of its revenue, as described in a Built to Sell interview.
Customers & Platforms
The Best AI Email Marketing Tool.
“What we love about Nitrosend is obviously it’s AI native, and it’s very, very easy for a non-technical person to just talk to AI and ask it to do a thing for them.”
Your Salon SupportBrayden Lee, PartnershipsAgency partner (revenue share)“I just want to tell Claude do it and go, baby. Let me review it at the end.”
Global Flourishing StudyMatthew Wilson, Developer“This is really sick. [...] But this is great. And I can do all of it on Claude itself.”
Harsh Sanghavi, Growth“One of the beautiful things that you guys have from an onboarding perspective is you have an MCP server, and that was basically how I validated whether or not your product was going to be good for my business.”
Blake Waldron“It’s not just using AI as a chatbot. [...] When I saw Nitrosend, that’s how I felt. We are reinventing email marketing finally.”

“I have all these agents that are built that are running this stuff, and you guys are great because you’re in that first wave [...] with companies built to be run by agents, not humans.”

Real marketplace emails
Platforms and switching
Questions people ask.
What emails should a two-sided marketplace set up first?
Seller onboarding emails that lead to a first listing, then a nudge for live listings with no sale, buyer activation, the marketplace transactional emails both sides rely on, a review request email and a sponsor inquiry reply. Supply comes first because a marketplace with no listings has nothing to sell. Add one weekly digest per side once those are live.
Can Claude or ChatGPT set up my marketplace email marketing?
Yes. Paste the prompt on this page into Claude or ChatGPT. It reads a short skill file, connects Nitrosend, lists the events your payments provider and backend emit, builds the six flows as drafts and sends you a test of each. Backend changes arrive as one pull request. You approve what goes live.
Do I have to switch from Customer.io, Resend or Mailchimp?
Not all at once. Your agent builds the six flows in Nitrosend as drafts, so nothing changes for your members until you switch one on. An email your platform already sends is not built twice, and when a Nitrosend flow replaces one, the old one is turned off first, so nobody gets two.
Will my agent send anything without asking me?
The prompt tells it to build drafts, send tests only to you, and ask before anything goes live, before DNS changes and before importing contacts. For a hard stop on top of that, turn on Safe Mode in Nitrosend and every send waits for your approval.
Can my platform give each member their own email account?
Yes. From the Clients page or the Partner API you create a client-owned Nitrosend account for a member, and your agent builds the brand kit, welcome flow and first drafts. You invite the owner when it is ready. They claim the account and pick a paid plan before it sends. You keep a revocable seat.
What does it cost?
Free to start: 5,000 emails up front, then 500 free every month. No card needed. Contacts are unlimited on every plan, so a large base of buyers and sellers costs nothing to store. Starter is $20 a month for 20,000 emails.
Six flows. One prompt.
