Mailcoach CLI
Use this skill when the user wants to manage email marketing through their Mailcoach instance. This includes managing email lists, subscribers, campaigns, transactional emails, templates, automations, tags, segments, and suppressions.
Prerequisites
The mailcoach CLI must be installed and authenticated. If a command returns a 401 error, the user needs to authenticate first.
mailcoach login
mailcoach list-email-lists
See rules/authentication.md for the full login flow.
How commands work
Commands are auto-generated from the Mailcoach OpenAPI spec. Always discover commands dynamically rather than guessing names.
mailcoach list
mailcoach <command-name> --help
Command naming
Commands use kebab-case derived from API operation IDs:
list-email-lists, create-email-list, show-email-list, update-email-list, delete-email-list
list-subscribers, create-subscriber, show-subscriber, update-subscriber
list-campaigns, create-campaign, send-campaign, send-campaign-test
list-transactional-mails, send-transactional-mail
list-tags, create-tag, list-segments, create-segment
trigger-automation
Parameter naming
- Path parameters like
{emailList} become required options: --email-list=<uuid>
- Query parameters like
filter[search] become optional options: --filter-search=<value>
- Both
snake_case and camelCase parameter names are converted to --kebab-case (e.g., book_id and bookId both become --book-id)
Sending data
mailcoach create-email-list --input '{"name": "Newsletter", "default_from_email": "hi@example.com"}'
mailcoach create-email-list --field name="Newsletter" --field default_from_email="hi@example.com"
mailcoach create-subscriber-import --email-list=<uuid> --field csv=@/path/to/subscribers.csv
--field values are sent as JSON by default. When any field contains a file (@ prefix), the entire request switches to multipart/form-data.
- You cannot combine
--field and --input in the same command.
Output formats
mailcoach list-email-lists
mailcoach list-email-lists --json
mailcoach list-email-lists --yaml
mailcoach list-email-lists --minify
mailcoach list-email-lists --H
mailcoach list-email-lists --output-html
Always use --json when you need to extract UUIDs or data from responses for use in subsequent commands.
Filtering, sorting, and pagination
mailcoach list-subscribers --email-list=<uuid> --filter-search="john" --sort=email --filter-per-page=50 --filter-page=2
--filter-search: fuzzy text search
--sort: field name, prefix with - for descending (e.g., --sort=-created_at)
--filter-per-page: results per page (max 100, default 15)
--filter-page: page number
Error handling
- 401: Authentication failed. Run
mailcoach login to re-authenticate.
- 422: Validation error. The response body contains details about which fields are invalid.
- 404: Resource not found. Verify the UUID is correct.
- Missing path parameter: The CLI tells you which
--option is required.
- All errors exit with a non-zero code, so you can chain commands with
&&.
- HTML error responses hide the body by default — add
--output-html to see them.
Common workflows
Email lists and subscribers
Campaigns
- rules/campaigns.md — Full campaign lifecycle: create, configure, test, send, and view statistics
Transactional emails
Templates and automations
Important notes
- Mailcoach is self-hosted: each user has a unique instance URL configured during
mailcoach login
- The OpenAPI spec is cached for 24 hours. Run
mailcoach clear-cache to force a refresh if commands seem outdated.
- UUIDs are used as resource identifiers throughout the API.
- When chaining commands (e.g., create a list then add subscribers), use
--json to extract UUIDs from responses.
