Loops: The Comprehensive Platform for Every Product, Marketing, and Transactional Email

In the modern software landscape, communication is the bridge between a product and its users. Loops emerges as the simplest and most effective way to send product email, marketing email, and transactional email through a single, unified platform. Designed to scale with your company from the initial waitlist phase all the way to an IPO, Loops provides the tools necessary to build meaningful connections through the inbox.

Trusted by industry leaders such as Framer, Linear, Perplexity, Sketch, and Reuters, Loops has established itself as the go-to solution for teams that value speed, simplicity, and a high-quality developer experience.

What is Loops?

Loops is an all-in-one email platform that eliminates the complexity of managing multiple services for different types of communication. By combining marketing automation with transactional capabilities and product-led emails, Loops allows growth and engineering teams to work in sync. Whether you are sending a welcome series to new signups or a critical billing update via Stripe, Loops ensures that every message is delivered reliably and looks professional.

One Platform, Every Email

Many companies struggle with fragmented data and inconsistent designs because they use different tools for marketing and transactional messages. Loops solves this by providing a single environment where your entire email strategy lives. This consolidation ensures that your branding remains consistent and your user data stays accurate across every touchpoint.

Built for Every Stage of Growth

From early-stage startups in the Y Combinator W22 cohort to established brands like Framer (a customer since Dec 2022) and Linear (a customer since Jan 2023), Loops is built to scale. It supports high-growth environments where speed is critical and bloat is a liability.

Features of Loops

Email Design from First Principles

Historically, designing emails that function correctly across every email client was a major technical hurdle. Loops has reimagined this process from the ground up.

• Universal Compatibility: Designs crafted within Loops are guaranteed to work in all supported email clients.
• Visual Customization: Users can easily adjust themes, including background colors (e.g., #1C1917), padding (24px), borders (1px solid), and border radius (6px) to match their brand identity.
• Human and Agent Interaction: Loops supports both human-led design and agent-integrated workflows, ensuring flexibility in how your emails are generated and sent.

A Delightful Developer Experience

Loops is built by developers, for developers. It simplifies the technical aspects of email management by focusing on core concepts: contacts, contact properties, events, and event properties.

• Simple API: If you understand the basics of REST APIs, you already know how to use Loops.
• Extensive Language Support: Loops offers libraries and documentation for Node, NextJS, Ruby, PHP, NuxtJS, and Laravel.
• High Adoption: With over 239.3K downloads per week on npm, the Loops integration is a proven choice for modern web applications.

Build Powerful Lifecycle Workflows

Once a user closes their browser tab, the inbox becomes your best opportunity for re-engagement. Loops provides a robust workflow builder to automate these interactions.

• Triggers: Start workflows based on specific events, such as userCreated.
• Logic and Branching: Use timers (e.g., wait 5 minutes or 3 days) and filters (e.g., check if a user is !activated) to create complex, responsive journeys.
• Action-Oriented Flows: Automatically send welcome emails, setup guides, or removal triggers if a user remains inactive after a set period (e.g., 14 days).

Growth Team Optimization

Loops moves beyond simple "open" rates to focus on what actually matters: revenue and conversions. By connecting Loops to your app, growth teams can track:

• Goal Conversions: Monitor transitions from Free to Pro plans (e.g., 3.2% conversion rates).
• Onboarding Completion: Track how many users finish your setup process (e.g., 68% success rate).
• Referral Engagement: Measure the effectiveness of referral link clicks (e.g., 12% click rate).

Marketing in Sync with Product

Loops ensures that your marketing efforts are never disconnected from your actual product data.

• Saved Segments: Create dynamic segments based on properties like "Plan is Pro" or "Signed up < 7 days ago."
• Automated Syncing: As users change their behavior in your app, their status in Loops updates automatically. This keeps segments like "Paying Customers" or "Didn't open last campaign" always accurate.

Seamless Stack Integrations

Loops is designed to sit on top of your existing data stack. It integrates seamlessly with the tools you already use:

• Authentication & Database: Supabase, Clerk, Auth0.
• Payments & Analytics: Stripe, PostHog.
• No-Code & Automation: Zapier, Make, Framer, Webflow, Bubble.
• Data Orchestration: Segment and Webhooks.

How to Use Loops

Setting up Loops is straightforward, whether you are a developer or a marketer. Below are the steps to get started with the platform.

1. Setting Up the Environment

For developers using Node.js, the integration begins with a simple command:

npm i loops

2. Creating Contacts via API

You can programmatically add users to your Loops account using the Contacts API. Send a POST request to https://app.loops.so/api/v1/contacts/create with a JSON payload:

{
  "email": "[email protected]",
  "firstName": "Alice",
  "lastName": "Smith",
  "source": "signup_form",
  "subscribed": true,
  "userGroup": "paying"
}

3. Constructing an Acquisition Workflow

To build a high-converting onboarding flow, follow this logic within the Loops workflow editor:

1. Start: Set a trigger for userCreated.
2. Timer: Add a delay (e.g., 5 minutes) before the first contact.
3. Send: Deliver a Welcome Email.
4. Branch: After 3 days, check a Filter to see if the user has !activated.
5. Action: If not activated, send a Setup Guide.
6. Exit: If the user remains !activated after 14 days, use a filter to remove them from the flow.

Use Cases

For Startups (Waitlist to Launch)

Loops is ideal for managing early-stage waitlists and transitioning those users into active product testers once the app launches.

For SaaS Growth Teams

Growth teams use Loops to move beyond basic email marketing. By tracking Goal Conversions like "Free to Pro" upgrades, they can refine their messaging to drive actual revenue.

For Developers (Transactional Reliability)

Developers rely on Loops for critical transactional emails, such as billing alerts via Stripe or authentication syncs via Clerk and Supabase.
