Overview
Loops and Keap serve completely different business types. Loops is a modern email platform for SaaS companies and startups, with a developer API, event-based triggers, and transactional email. Keap is an all-in-one business platform for service businesses, with CRM, invoicing, scheduling, and email marketing bundled together.
The only shared feature is the ability to send email. Everything else about these platforms differs.
SaaS Email vs Business Suite
Loops focuses on email for software products. Custom events trigger lifecycle messages. Transactional and marketing email live in one platform. The API is designed for developers who want programmatic control over messaging.
Keap focuses on running a service business. The CRM tracks client relationships. The visual pipeline manages sales stages. Invoicing handles billing. Appointment scheduling books client time. Email marketing is one piece of a broader business management tool.
The Price Gap
Loops costs $79/month at 10k contacts. Keap costs $299/month. The $220 difference reflects the scope of each platform. Loops provides email only. Keap provides email plus CRM, invoicing, scheduling, landing pages, and pipeline management.
If you need just email, Loops is the better value. If you are currently paying for separate CRM, invoicing, scheduling, and email tools, Keap's bundled price may actually save money compared to buying each tool individually.
Developer Experience
Loops provides a modern API that SaaS developers appreciate. Clean endpoints, good documentation, and event-based architecture integrate naturally with product codebases.
Keap has a basic API that covers essential operations but is not designed for developer-centric workflows. Service businesses typically interact with Keap through the visual interface, not programmatically.
For SaaS Companies
Loops is a solid SaaS email choice but lacks Stripe integration for subscription billing events. Sequenzy at $49/month provides subscription-aware automation that triggers based on trial conversions, plan changes, and churn. Keap is not relevant for SaaS companies.
