Loops – Email Platform for SaaS Marketing and Transactional Mail

Description

Loops is an email platform for SaaS teams. Official pages describe one product for marketing, product or lifecycle, and transactional email, all from the same contact record. The official site also presents a visual editor, event-driven workflows, a REST API, a CLI, an MCP server and agent skills, plus integrations such as Stripe, Clerk, Supabase, Segment, Zapier, Framer, Make, Webflow, PostHog and Auth0. The service is operated by Astrodon Corporation. Official Terms of Use, last updated 15 December 2025, are governed by the laws of the State of Delaware. Official About copy says Loops started in 2022 as a Y Combinator company, launched publicly in September 2023, and announced a $3.2 million seed round led by Craft Ventures. Do not confuse this product with Viral Loops, a separate referral-marketing tool already listed on Digital Marketing Supermarket.

Public prices were checked on 15 November 2026 (Europe/London). There is a free plan at $0 that official FAQs say does not expire: you can store unlimited contacts, and you get up to 4,000 marketing and transactional sends combined, in any rolling 30-day window, to your first 1,000 contacts, with a “Powered by Loops” footer. Paid Growth starts at $49 a month for up to 5,000 subscribed contacts, with unlimited sends and no Loops branding. Unsubscribed contacts do not count toward the price. Official pages say there are no seat fees and no separate per-send charges on paid plans. For a fuller look, read our Loops review 2026.

Who It’s For

• SaaS product and growth teams that want marketing campaigns, onboarding or trial workflows, and transactional mail such as password resets and receipts in one platform, rather than splitting those sends across two vendors.
• Engineering teams that want an API, SDKs, a CLI and an MCP server so coding agents or backend jobs can create contacts, fire events and send transactional email, while marketers still edit in a visual editor.
• Teams that want pricing based on subscribed contacts, with no seat fees, and a free plan they can try without a time-limited trial ending.
• Teams that already use tools such as Stripe, Clerk, Supabase or Segment and want those events to update a single contact record.
• It is not a referral or contest platform, and it is not the same product as Viral Loops. It is also a poor fit if you need a guaranteed refund on prepaid fees, or if you only need a simple newsletter tool with no product events.

Core Capabilities

• One contact record for every email type. Official pages say marketing, product and transactional email all use the same contact, with segments, properties and mailing lists. Transactional mail can still reach contacts who have unsubscribed from marketing, subject to delivery suppressions.
• Campaigns and workflows. Official docs describe one-off campaigns to a segment, and workflows triggered by signups, property changes or app events, with timers, branches, audience filters and experiments.
• Visual editor and reusable styles. Official pages describe a visual email editor with themes and components, plus a way to edit the same emails from code (officially called LMX).
• API, CLI, MCP and agent skills. Official developer pages describe a REST API, typed SDKs, a CLI, an MCP server and published skills so coding agents can set up Loops, migrate mail and draft campaigns.
• Deliverability safeguards. Official copy says the team reviews sending, signs mail with DKIM, and automatically suppresses hard bounces and spam complaints. The footer links a SOC 2 trust centre, a DPA and the EU-US Data Privacy Framework list.

Key Features

• Free plan with no expiry, as stated in official FAQs, including 4,000 combined sends per rolling 30 days to your first 1,000 contacts.
• Growth and Enterprise plans with unlimited marketing and transactional sends, no Loops branding, and published rate limits (10 emails per second on Free; 1,000 per second on paid plans). Emails over the rate limit are enqueued.
• No seat fees, and no separate per-send charge on paid plans. Price is based on subscribed contacts only.
• Integrations listed on the official site include Stripe, Clerk, Supabase, Segment, Zapier, Framer, Make, Webflow, PostHog and Auth0, plus CSV upload and webhooks.
• Campaign goals and split tests, as described on official feature pages, to count contacts who reach a state such as upgrading to a paid plan.

Plans & Pricing

Prices below are from the official pricing page on 15 November 2026 (Europe/London), shown in US dollars. Official FAQs say paid plans are priced by subscribed contacts, and that unsubscribed contacts never count. Official Terms mention monthly or annual billing cycles at checkout, but the public pricing page did not show a yearly toggle when checked. Official Terms also say amounts paid are not refunded, and that cancelling renewal does not return a prepaid or unused portion, except where the law requires it or the Terms specifically provide otherwise.

Pros & Cons

Where It Fits

Loops sits in email marketing and marketing automation, with a narrower brief than a general all-in-one marketing suite: it is a SaaS email platform for marketing, lifecycle and transactional mail on one contact record. For a broader all-in-one marketing platform, see Mailchimp. For ecommerce-led email and SMS, see Klaviyo. For a creator-focused newsletter and audience tool, see ConvertKit. For automated messaging across email, push and SMS, see Customer.io. For a more general email-marketing suite with landing pages and automation, see MailerLite. Transactional specialists such as SendGrid, Mailgun and Postmark cover sending APIs without the same all-in-one marketing editor. Browse the directory of AI tools for digital marketers.
