Loops

Overview

Loops is email marketing software built specifically for SaaS teams. It unifies product email, marketing email, and transactional email in a single platform so teams can manage every message from waitlist to IPO without juggling multiple tools.

Framer, Linear, Perplexity, Granola, Clerk, Sketch, and Reuters are among the teams using Loops. It combines an email designer built from first principles, a developer-friendly API and SDK, lifecycle workflow builder, and native integrations with the modern SaaS stack. The company is backed by Y Combinator (W22).

Key Benefits

• Manage product, marketing, and transactional email from one platform instead of separate tools.
• Free plan includes up to 4,000 sends per month to 1,000 subscribed contacts with no credit card required.
• Paid plans include unlimited email sends with no per-seat fees for team members.
• Emails designed in Loops render correctly across all major email clients out of the box.
• Track goal conversions such as upgrades, onboarding completion, and referral clicks to measure email-driven revenue.
• Build segments from contact properties and engagement data that stay synced with the product automatically.

How It Works

You connect Loops to your app via its API or one of its native integrations (Supabase, Clerk, Stripe, etc.) to sync contacts and events. Then you design emails using reusable assets and themes, or send them programmatically via the Loops API from Node.js, Ruby, PHP, Next.js, NuxtJS, or Laravel. You build lifecycle workflows by setting triggers (e.g., a new user signs up), adding timers and branches, and sending automated email sequences — all from a visual builder.

Use Cases

• SaaS founders and engineers — send onboarding sequences, product updates, and transactional emails from a single API and dashboard.
• Growth teams — build lifecycle workflows triggered by user events, then measure upgrades, churn reduction, and referral clicks as goal conversions.
• Marketing operators — create reusable email segments from contact properties and engagement data that stay in sync with the product database.
• Developer teams — integrate with Loops via REST API, webhooks, or SDKs for Node.js, Next.js, Ruby, PHP, NuxtJS, and Laravel without custom email infrastructure.
• Early-stage startups — use the free plan to send weekly product emails to up to 1,000 subscribed contacts and test email workflows before scaling.

Why Choose This Product

Loops is best suited for SaaS teams that want a single platform for all email types — marketing, lifecycle, and transactional — without paying separate per-seat fees or per-send charges on paid plans. The free plan includes Loops branding and is limited to 10 emails per second, while paid plans unlock unlimited sends at up to 1,000 emails per second. Pricing is based on subscribed contacts, not on volume of emails sent.
