Email for agents

Let Claude Code, Codex, ChatGPT, Cursor, and your own coding agents install Loops, migrate your stack, send events, and test transactional email using the CLI, API, SDKs, and agent skills.

Use agents for setup, migrations, content, events, and testing

MCPReleased

Connect your agent to Loops over MCP. Read and write contacts, events, and content from any client.

SkillsReleased

Small modules that teach your coding agent how to work with Loops. Install each with one command.

Platform APIReleased

REST API with an OpenAPI spec. Endpoints for contacts, events, transactional email, campaigns, and email content.

CLIReleased

Manage contacts, send events, deliver transactional emails, and test your integration from your terminal.

LMXReleased

Loops Markup Extended, an XML format for email content. Create and update emails programmatically with the Content API.

Campaign APIReleased

Create draft campaigns, content and all, straight from the API. Review and send from the dashboard.

Transactional APIReleased

Send transactional emails with dynamic data variables, right from your backend.

SDKsReleased

Official SDKs for JavaScript, Go, Nuxt, PHP, and Ruby. Use the API skill to choose an SDK for your stack.

Workflows APIReleased

Create and manage workflows from the API, and trigger them with events.

/migrateIn Progress

Move from your current email provider using the API skill and a migration guide. The dedicated /migrate skill is on the roadmap.

/setupNext

Install Loops in your app with the API skill. A dedicated /setup skill that detects your stack and wires auth is on the roadmap.

What it looks like in practice

Install Loops

Install Loops in my Next.js app

Detected Next.js. I installed the JavaScript SDK, wired LOOPS_API_KEY from .env, set up a contact sync route with a transactional send example, and wrote you a testing checklist.

Migrate your stack

Audit my email setup and map it to Loops

I scanned your codebase and found every send, template, and webhook. Each one maps to a Loops equivalent, so I swapped the API calls and rebuilt your templates in LMX through the Content API.

API reference

Send events

Send a cancellation event into Loops

Your Stripe webhook handler now calls the Loops events API when a subscription is canceled. I set the event name, mapped plan, reason, and date, and created the contact properties it needs.

Draft campaigns

Draft a product update campaign

I wrote the email in LMX, created a draft campaign, then added the subject, sender, and full content through the Content API. Tell me what to change and I’ll revise the copy.

Test transactional email

Test this transactional email from the terminal

Sent a test through the CLI with your transactional ID and sample data variables. The send came back confirmed, so check your inbox for the rendered email.
