# Mailtarget Email
Send emails and manage email infrastructure via the Mailtarget API.
Setup
Set the `MAILTARGET_API_KEY` environment variable with your Mailtarget API key.
Get your API key from the Mailtarget dashboard → Settings → API Keys.
Sending Email
Use `curl` or any HTTP client. All requests go to `https://transmission.mailtarget.co/v1` with `Authorization: Bearer $MAILTARGET_API_KEY`.
Simple send
```bash curl -X POST https://transmission.mailtarget.co/v1/layang/transmissions \ -H "Authorization: Bearer $MAILTARGET_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "to": [{"email": "[email protected]", "name": "Recipient"}], "from": {"email": "[email protected]", "name": "Your App"}, "subject": "Hello from Mailtarget", "bodyHtml": "<h1>Hello!</h1><p>This is a test email.</p>", "bodyText": "Hello! This is a test email." }' ```
A successful response returns `{"message": "Transmission received", "transmissionId": "..."}`.
Template-based send
Use `templateId` with `substitutionData` instead of bodyHtml/bodyText:
```json { "to": [{"email": "[email protected]", "name": "User"}], "from": {"email": "[email protected]", "name": "Your App"}, "subject": "Welcome, {{name}}!", "templateId": "welcome-template", "substitutionData": {"name": "User", "company": "Acme"} } ```
Tracking options
Control click and open tracking per transmission:
```json { "optionsAttributes": { "clickTracking": true, "openTracking": true, "transactional": true } } ```
Set `transactional: true` for transactional emails (password resets, receipts) to bypass unsubscribe preferences.
Attachments
Include base64-encoded attachments:
```json { "attachments": [{ "filename": "report.pdf", "mimeType": "application/pdf", "value": "<base64-encoded-content>" }] } ```
Managing Templates
- List: `GET /template?page=1&size=10&search=keyword`
- Create: `POST /template` with `{"id": "slug", "name": "Display Name", "html": "<html>..."}`
Managing Sending Domains
- List: `GET /domain/sending`
- Create: `POST /domain/sending` with `{"domain": "example.com"}`
- Verify: `PUT /domain/sending/{id}/verify-txt`
- Check SPF: `GET /domain/sending/{id}/spf-suggestion`
Autonomous Domain Setup (with cloudflare-dns skill)
When paired with the `cloudflare-dns` skill, the agent can set up a sending domain end-to-end with zero manual DNS editing:
- Create sending domain: `POST /domain/sending` with `{"domain": "example.com"}`
- Read required DNS records from the response: `spfHostname`, `spfValue`, `dkimHostname`, `dkimValue`, `cnameHostname`, `cnameValue`
- Add SPF TXT record in Cloudflare using `spfHostname` and `spfValue`
- Add DKIM TXT record in Cloudflare using `dkimHostname` and `dkimValue`
- Add CNAME record in Cloudflare using `cnameHostname` and `cnameValue` (set `proxied: false`)
- Verify domain: `PUT /domain/sending/{id}/verify-txt`
- Confirm status via `GET /domain/sending/{id}` — check `spfVerified`, `dkimVerified`, `cnameVerified`
Install the companion skill: `clawhub install cloudflare-dns`
