Loops Review 2026: The Modern Email Platform for SaaS?

Loops focuses on doing a few things exceptionally well rather than trying to do everything:

• Event-Based Automation — Trigger emails based on events from your product. User signs up? Send a welcome sequence. User activates a feature? Send a congratulations email. Simple, powerful, and developer-friendly.
• Transactional Emails — Send password resets, order confirmations, and other transactional emails from the same platform as your marketing emails. No need for a separate service like SendGrid. If you only need an SMTP relay, see our best free SMTP servers.
• Marketing Campaigns — Create and send one-time campaigns to segmented audiences. The editor is clean and fast, though less feature-rich than Mailchimp's.
• API-First Design — Everything in Loops is accessible via API. Integrate with your product in minutes, not days. The API documentation is excellent.
• Contact Management — Simple contact management with custom properties and event tracking. Not a full CRM, but enough for SaaS email needs.
• Team Collaboration — Multiple team members can access campaigns and automations with role-based permissions.

Ease of use is Loops' superpower. The interface is beautifully designed — fast, clean, and intuitive. If you've used modern tools like Linear, Notion, or Vercel, Loops will feel instantly familiar.

Setting up your first campaign takes minutes. The email editor is minimal but effective — you won't find dozens of template options, but the ones available are well-designed and mobile-responsive. The focus is on getting your email sent quickly rather than spending hours on design.

For developers, the API integration is remarkably simple. Most teams can start sending event-triggered emails within an hour of signing up. The documentation is clear, well-organized, and includes code examples for popular frameworks.

Loops takes a different approach to automation than traditional ESPs. Instead of complex visual workflow builders, Loops uses a simpler event-based model: when X happens, send Y.

This covers the most common SaaS automation needs: welcome sequences triggered by signup, onboarding emails triggered by product events, re-engagement emails triggered by inactivity, and upgrade nudges triggered by usage milestones.

The trade-off is that Loops can't handle the deeply complex, multi-branch automation workflows that Customer.io or ActiveCampaign excel at. If you need conditional logic with 10 branches based on different user behaviors, Loops isn't there yet. But for 90% of SaaS email automation needs, its simpler approach is faster to set up and easier to maintain.

Loops supports SPF, DKIM and DMARC on your own sending domain, and every plan, including Free, includes all features. Marketing and transactional email run on the same platform, so authentication covers both.

BestSends hasn’t published an inbox-placement test of Loops. As a younger platform it has less public track record than long-established ESPs; for any sender, authentication, list quality and engagement decide placement more than the tool. See our deliverability explainer.
