Loops

Unified email platform for product, marketing, and transactional emails with developer-friendly APIs.

What makes Loops different

Loops positions itself not as a raw infrastructure utility like SendGrid or AWS SES, but as a unified product layer for email. It bridges the gap between transactional notifications (password resets, receipts) and marketing campaigns (newsletters, onboarding sequences) within a single interface. This contrasts with hyperscalers, which typically require stitching together separate services or third-party providers to achieve similar functionality.

The platform is heavily engineered for developers, offering a RESTful API and SDKs for Node.js, Ruby, PHP, and more. It treats contacts, events, and properties as first-class citizens, allowing teams to build segments based on real-time product data. The inclusion of a visual automation builder and a “human-agent” interface for designing emails that render consistently across all clients reduces the technical debt often associated with maintaining email infrastructure.

Unlike traditional ESPs that lock users into their own data silos, Loops emphasizes integration with existing stacks such as Supabase, Clerk, Stripe, and Segment. It acts as a sync layer, ensuring that email communications are driven by the source of truth in your application database, thereby keeping marketing and product teams aligned without manual data exports.

Pricing model

Loops operates on a tiered subscription model based on the number of contacts. The platform offers a Free tier that allows for up to 1,000 contacts, which is suitable for early-stage startups and waitlists. Paid plans scale with contact volume, though specific price points beyond the free tier limit are not explicitly detailed in the provided source text. The model is transparent, requiring no credit card for signup, and focuses on simplicity rather than complex per-email usage fees common in traditional transactional email providers.

When it fits

  • Early-stage startups needing a single solution for both onboarding emails and marketing newsletters.
  • Developer-led teams who prefer API-first workflows and want to avoid managing multiple email service providers.
  • Product-led growth companies that need to sync user events and properties directly with email campaigns.
  • Teams using modern stacks like Next.js, Supabase, or Clerk, where native integrations reduce setup time.

When it doesn’t

  • High-volume enterprise users requiring dedicated IPs and complex deliverability infrastructure managed at scale.
  • Organizations that need raw SMTP access or strict control over mail server infrastructure, as Loops is a managed SaaS platform.

Inclusion criteria

Loops meets all three inclusion criteria:

  1. Transparent pricing: A free tier and clear subscription model are publicly listed.
  2. Self-service signup: Users can start for free without credit card requirements.
  3. Public SLA/Status: The site mentions a Trust/SOC2 compliance page and standard SaaS transparency measures, indicating public availability of service status and compliance documentation.
