Your newsletter. Your agent runs it.
Give your agent the Djinnletter skill. It imports your list, sets up your sender domain, schedules the issue and sends it when you say so.
Paste this into your agent
Fetch and follow the instructions at https://app.djinnletter.com/setup.md to set up Djinnletter for me.
Ask in plain words.
You talk to your agent. Your agent talks to Djinnletter. Nobody opens a dashboard unless they feel like it.
-
“Import my customers from this file and tag the ones from Valencia.”
AudienceCSV import of any size, sync from your CRM, your own fields on each person, tags to group them.
-
“Send Thursday's issue to VIPs at nine. Show me a test first.”
IssuesDrafts, previews, a test copy to your inbox, send now or on a schedule, to everyone or to tags.
-
“Greet people by their first name.”
Personal touchMerge tags such as
{{first_name|there}}in the subject and the body, with a fallback when the data is missing. -
“Welcome every new signup with three emails over a week.”
SequencesA signup form with double opt-in for your site, and a series of emails on the days you choose.
-
“When someone buys, start the thank-you series.”
EventsYour own events start a sequence: from your server, or from Stripe, Zapier or your shop through a private URL.
-
“What did people click last month?”
ResultsDelivery, opens, clicks and unsubscribes per issue, and the raw data for your agent to analyze.
-
“Tell my CRM when someone unsubscribes.”
WebhooksSigned messages to your tools when people join, change, click or leave.
Three steps. One of them is pasting.
No setup wizard. No onboarding call. Your agent reads the manual, which is more than we can say for most of us.
-
1
Paste the prompt
Your agent reads the instructions and opens one page for you to approve. No API key to copy around.
-
2
It sets you up
Your list, your sender domain and its DNS records, your signup form. It tells you exactly what is left.
-

You ask, it sends
One issue or the whole routine. Bring your own words or ask your agent for a draft.
Pay for emails. Nothing else.
€1 = 1,000 credits

- Every send must be fully funded.
Cost examples
| Audience | Issues | Emails | Cost |
|---|---|---|---|
| 1,000 | 1 | 1,000 | €1 |
| 5,000 | 4 | 20,000 | €20 |
| 10,000 | 4 | 40,000 | €40 |
| 50,000 | 2 | 100,000 | €100 |
No tiers, no seats, no "contact sales". Taxes not included.
- We have… 500 subscribers.
- This month we send 2 newsletters. Okay, maybe 3.
- So that is 1,500 emails.
- That comes to… €1.50. No subscription, no nonsense.
The chimp's cheapest subscription would charge you €11.74 a month, whether you send or not.
First-year price, checked in November 2026. They do more things. We just get the monkey off your back.
The big decisions stay yours.
Your agent does the work. It does not get the credit card.
- Sending
- The skill tells your agent to ask you before every send, unless you already said go ahead.
- Money
- A key can read your balance. Only you can add credits or save a card.
- Sequences
- Your agent prepares them. Nobody gets one until you press Activate.
- Readers
- Someone who unsubscribed, bounced or complained is never added back, by anyone.
Djinnletter next to a typical platform.
We are not the best at everything, and we are not trying to be. Use Djinnletter to get the newsletter monkey off your back. Your agent carries the monkey.
| Area | Djinnletter | Typical platform |
|---|---|---|
| Setup | Paste one prompt. Your agent does the rest and asks you to approve. | Sign-up forms, wizards and settings pages. |
| Workflow | Your agent runs the newsletter. | You run the newsletter from a dashboard. |
| Interface | Skill, CLI, REST and OpenAPI. Dashboard included. | Dashboard-first. API access varies. |
| Billing | €1 per 1,000 accepted emails. Prepaid. No monthly fee. No contact limit. | Often monthly tiers by contacts, sends or features. |
| Audience | CSV import and export, sync from your CRM, your own fields. Multiple tags per subscriber. Target one or more tags. | Often includes deeper segment builders. |
| Content tools | Write it yourself or use your agent. Four starter templates, your own HTML templates, merge tags, previews and brand assets. | Usually stronger visual editors and larger template libraries. |
| Delivery | Send now or schedule. Idempotent sends and delivery metrics. | Scheduling is common. Retry models vary. |
| Automation | Signup form with double opt-in, sequences started by signups or your own events, and webhooks in and out. | Forms and automations are common. Experiments and visual builders are often included. |

How is it different from other platforms?
Your agent runs it, so you do not live in a dashboard. You pay per email, not per month. Others have fancier editors and more experiments. We are not trying to be the best at everything: we get the newsletter monkey off your back.
Which agents work with it?
Any agent that can read a web page and make web requests: Claude, Codex, OpenClaw, Hermes and others. The prompt points it at the instructions.
Do I need to know how to code?
No. That was the whole point. You paste one prompt and answer your agent's questions. There is a dashboard for when you want to look.
Whose address do the emails come from?
Yours. Your agent adds your domain and tells you which DNS records to publish. Emails go out once the domain is verified.
Can my agent run the whole workflow?
Yes, over REST and OpenAPI: audience, drafts, templates, scheduling, sends, sequences and results. Activating a sequence and anything about money stay with you.
Can subscribers have multiple tags?
Yes. Target one or more tags. Each subscriber is included once. No AND rules or exclusions yet.
How long does a large send take?
A big audience goes out in parts over minutes, at the pace email providers accept. You see the progress and can leave the page.
How do I report a bug or ask for a feature?
Write to founders@djinnfoundry.com, or use Feedback in the dashboard settings. Two humans read every message.
When is a credit consumed?
When one email is accepted for one recipient. Inbox placement is not guaranteed.
How does auto-recharge work?
It adds one amount you set when balance is low. It never chains charges for one send.

Paste the prompt, approve once, and send your first 1,000 emails free.
