What is Loops?

Loops is an email marketing and transactional email platform designed from the ground up for software companies. Instead of bending a generic newsletter tool like Mailchimp to fit product data, Loops treats contacts, contact properties, events, and event properties as first-class citizens, so you can send a broadcast newsletter, an onboarding drip, and a password-reset email from the same account. It handles the full customer lifecycle, or as the company puts it, “from waitlist to IPO.”

The product is used by teams like Framer, Linear, Perplexity, and Y Combinator, which tells you the audience: developer-led SaaS companies that want clean deliverability and a simple API without paying enterprise prices for a tool like Customer.io. On July 1, 2026, Loops launched Goals, a feature that gives every campaign a conversion target and measures whether the send actually moved the number, alongside a refreshed three-panel workflow builder that brings automations in line with the rest of the editor.

What Are Loops’s Key Features?

Goals: conversion targets for every campaign

Goals is the headline addition. You attach a goal to a draft campaign, define the audience, pick the conversion state that counts as success (plan changes to paid, onboarding completed, a demo booked), and set an attribution window. Once the campaign sends, Loops tracks impressions, enrollments, and conversions across that window, so instead of celebrating a 40% open rate you can see “124 free-to-paid upgrades at 3.2%.” It measures activation, upgrades, purchases, retention, or any contact state that proves the email worked.

Unified marketing and transactional email

Most tools force you to run marketing email in one product and transactional in another. Loops sends both from the same platform, with transactional email included at no additional cost on paid plans. That means your welcome emails, receipts, and password resets share the same contact data, templates, and analytics as your campaigns.

Developer-friendly API and integrations

The API is built around contacts, properties, and events, so engineers can sync product data and fire event-triggered emails in a few lines of code. Native integrations include Stripe, Clerk, PostHog, Zapier, and Webflow, letting you segment by plan, role, company size, lifecycle stage, and product activity without a data pipeline.

Visual workflows and segmentation

The lifecycle workflow builder offers triggers, timers, branching, and conditional logic on a visual canvas, now redesigned into a consistent three-panel layout. Dynamic segments update automatically as product data changes, and the email editor is purpose-built to render correctly across major clients.

How Much Does Loops Cost?

Loops starts free with up to 1,000 subscribed contacts and 4,000 sends per month, with every feature included and only a Loops branding footer added. Paid plans begin at $49/mo for 5,000 contacts, and crucially, pricing is based on subscribed contacts synced to Loops, not on send volume, so you never get billed per email or per team seat. Higher tiers scale to roughly $99/mo at 10,000 contacts, $199/mo at 25,000, and $399/mo at 100,000.

Compared to Customer.io, whose Essentials plan starts at $100/mo for 5,000 profiles, Loops is roughly half the price at the same contact count while bundling transactional email for free. Against Resend, which is transactional-only and cheaper for pure API sends (Pro from $20/mo), Loops costs more but replaces two tools by covering marketing and lifecycle email as well.

Who Is Loops Best For?

Loops is squarely aimed at early and growth-stage SaaS companies that live inside their product data and want email that reflects it. If your emails are triggered by what users do in the app, and you care whether a campaign drove upgrades rather than just opens, Loops fits.

Use Loops if you run a SaaS product, want marketing plus transactional email in one place, value a clean API and integrations with Stripe, Clerk, and PostHog, and want to measure campaigns against real conversions via Goals.

Skip Loops if you run an ecommerce store, agency, or content business rather than SaaS, need a deep native CRM with historical contact records, or only need cheap transactional API sends, in which case Resend is a better-priced fit.

Best Loops Alternatives

Loops sits between lightweight transactional tools and heavyweight lifecycle platforms. Here are the three worth comparing.

Customer.io

The enterprise-grade lifecycle messaging platform with deep segmentation, multi-channel (email, SMS, push), and powerful workflows. It is far more capable but also far pricier, with Essentials starting at $100/mo for 5,000 profiles and Premium at $1,000/mo. Choose it when you have outgrown Loops’s automation depth and need multichannel.

Resend

A developer-first transactional email API with excellent deliverability and a generous free tier (3,000 emails/mo). Pro plans start at $20/mo. It is cheaper and simpler than Loops for pure API sends but has no built-in marketing campaigns, visual workflows, or conversion goals, so you would pair it with a separate marketing tool.

Mailchimp

The best-known general-purpose email marketing platform, strong on templates, audience management, and ecommerce integrations. It is a better fit for non-SaaS businesses but was never built around product events and API triggers, so SaaS teams often find it clumsy for lifecycle email despite its broad feature set.

Final Verdict: Is Loops Worth It?

Loops has quietly become the default email platform for developer-led SaaS, and it earns that with a clean API, unified marketing plus transactional sending, and contact-based pricing that does not punish you for sending more. The July 2026 Goals launch pushes it further ahead by answering the question every founder actually cares about, which is not “did they open it” but “did it drive an upgrade.” That is a genuinely useful shift that most email tools still ignore.

The trade-offs are real: it is SaaS-only, it lacks a full CRM and historical contact data, its automations are not as deep as Customer.io’s, and costs climb steadily as your list grows. But for the founder or growth team it targets, Loops is one of the easiest email platforms to recommend right now. If you run a SaaS product and want marketing, lifecycle, and transactional email in one tool that measures real conversions, it is well worth starting on the free plan.
