Loops

Loops is an email platform built for SaaS and software companies. It handles marketing emails, product and lifecycle emails triggered by user behaviour, and transactional emails such as password resets and receipts, in one tool designed to feel modern and simple. Its premise is that most email tools serve either marketers or developers but not the way startups actually work. Traditional marketing platforms are built for e-commerce campaigns, while transactional services such as SendGrid require engineering effort for everything. Loops brings both together: product teams send event data from their app via an API or integrations, and then marketers and founders design emails and automated sequences in a clean editor without needing code for every change. The workflow suits product-led growth. Loops can trigger onboarding sequences when someone signs up, nudge users who have not activated a key feature, send upgrade prompts and handle churn win-back, while also sending newsletters and product announcements to the whole audience. Contact properties and segments come from product data, and an integration ecosystem connects tools such as Stripe, Segment, Supabase and Clerk. Emails are designed to look clean and be readable on any device, and templates help teams start quickly. Pricing is based on the number of contacts, with a free tier for small audiences, and the product is deliberately focused rather than sprawling. The trade-off is that companies needing complex multi-channel journeys, SMS and push notifications, or very large enterprise features may need broader customer engagement platforms. Alternatives include Customer.io for powerful behaviour-based messaging across channels; Resend and Postmark for developer-focused transactional email; Intercom for in-app and email messaging; Kit and MailerLite for creator and small-business newsletters; and Braze for enterprise customer engagement. Choose Loops when you are a SaaS team that wants marketing, product and transactional email in one modern tool without heavy setup.
