Loops
6.8/10Loops is an email platform for SaaS companies that combines marketing campaigns, event-triggered lifecycle automations and transactional email in one tool.
Data last updated November 2026 · Our methodology
Overview
Loops is an email tool built for software companies. It puts marketing broadcasts, automated lifecycle sequences (which Loops calls loops) and transactional email such as receipts and password resets on a single contact record, so product events and email data do not need syncing between separate tools. Developers can send events and contact properties through a REST API, official SDKs and webhooks. Marketers and founders build emails in a block-based visual editor and target them with audience filters based on contact properties and events. A Goals feature tracks conversions such as upgrades or activations instead of only opens and clicks, and split testing comes at no extra charge. Pricing depends on the number of subscribed contacts, not seats or sends. The Free plan covers up to 1,000 contacts and 4,000 sends per rolling 30 days, and adds a Loops footer. Growth starts at $49 per month for 5,000 contacts with unlimited sends. Third-party reviews put the larger tiers at roughly $99 for 10,000 contacts and $399 for 100,000. Enterprise pricing is custom and adds priority support and migration help. Native integrations include Stripe, Clerk, Supabase, PostHog, Segment, Webflow, Zapier and Make. The main limitation is focus. Reviewers say Loops suits SaaS products but is a poor fit for ecommerce, agencies or newsletter-first businesses. Its automation and behavioural segmentation are also shallower than Customer.io's, and it has no SMS or push channels.
Our Rating
Who Loops is best for
Good fit
Loops is a Y Combinator company built for SaaS startups, with a free tier and contact-based pricing.
Non-technical marketers can send broadcasts and build sequences in the visual editor without engineering help.
Less suited
The pricing is affordable, but reviewers say Loops fits software companies far better than general small businesses.
An Enterprise tier covers 1.5 million or more contacts with priority support, but the automation depth trails larger platforms.
MakerStack advises agencies to skip Loops because of its SaaS focus.
