Overview

Brevo (formerly Sendinblue) and Loops serve different markets. Brevo is a budget-friendly all-in-one marketing platform for SMBs. Loops is a modern email platform built specifically for SaaS. The choice depends on what kind of business you're running. See our Brevo comparison and Loops comparison pages for more detail.

The Pricing Difference

Brevo charges by email sends. You can have unlimited contacts on some plans but pay for each email. Loops charges by contacts with unlimited sends included. For SaaS companies sending many lifecycle emails per user, Loops is often better value. For low email volume, Brevo's model can be cheaper.

All-in-One vs Focused

Brevo includes SMS, CRM, landing pages, and WhatsApp. It's a full marketing suite in one platform. Loops focuses on email only and does it well. For marketing teams wanting everything integrated, Brevo wins. For SaaS founders wanting simplicity and focus, Loops wins.

SaaS-Specific Features

Loops is purpose-built for SaaS. The events API is a core feature, not an afterthought. Lifecycle email patterns are built-in. Brevo can do SaaS email, but it's general-purpose. For behavioral automation based on product events, Loops understands the use case better.

Automation Limits

Brevo limits marketing automation to 2,000 contacts on the Starter plan. For full automation, you need the Business tier at $18/month for 5k emails. Loops includes unlimited automation on all paid plans starting at $49/month. For automated sequences without limits, Loops is clearer.

The Stripe Question

Neither has native Stripe integration. Both require Zapier or custom API work for payment-triggered emails. If Stripe billing integration is critical for your SaaS, Sequenzy offers native OAuth connection with revenue attribution.

Making the Choice

Choose Brevo for: all-in-one marketing, SMS and WhatsApp, built-in CRM, budget flexibility. Choose Loops for: SaaS-specific email, unlimited sends, simplicity and modern UI. For SaaS with Stripe integration needs, consider Sequenzy as a focused alternative.

Modern Design vs Feature Breadth

Loops represents a newer generation of email tools that prioritize developer experience, clean design, and focused functionality. Its interface feels contemporary - fast, uncluttered, and purpose-built for SaaS teams. Brevo's interface, while functional, shows its age and the complexity that comes from being an all-in-one platform.

This design difference matters more than it might seem. Marketing teams spend hours in their email platform every week. A clean, intuitive interface reduces friction, speeds up campaign creation, and makes it easier to train new team members. Brevo's feature richness comes at the cost of interface complexity.

For SaaS founders who value developer-friendly tools with modern UX, Loops provides a more enjoyable daily experience. For marketing teams that need every channel accessible from one dashboard regardless of interface polish, Brevo's breadth compensates for its design trade-offs.

The Events API as Core Architecture

The most significant technical difference between these platforms is how they handle product events. Loops treats its events API as a foundational architectural concept - product usage events flow in, and the entire automation system is built around responding to those events. This event-driven approach maps naturally to how SaaS products generate user data.

Brevo has event tracking available but it feels like an addition rather than a foundation. The platform was designed around contact lists and campaign broadcasts, with behavioral triggers added later. For SaaS companies that want their email automation deeply connected to product usage patterns, this architectural difference affects how naturally you can build lifecycle workflows.

The practical impact: building an onboarding sequence that responds to feature adoption milestones is straightforward in Loops because the events API makes product data a first-class concept. In Brevo, the same workflow requires more configuration and often feels like you are working against the platform's natural grain.

Pricing Model Economics for SaaS

The per-email versus per-contact pricing debate is particularly relevant for SaaS companies. SaaS lifecycle email programs tend to be high-frequency - onboarding sequences, feature announcements, usage reports, re-engagement campaigns, and transactional notifications can easily generate 10-20 emails per user per month.

At 10,000 contacts sending 15 emails per month (150,000 emails), Brevo's email-volume pricing could cost $45-65/month. Loops charges approximately $99/month for 10,000 contacts with unlimited sends. The gap narrows significantly at higher sending frequencies, and Loops becomes cheaper for very active lifecycle programs.

The key insight is that SaaS email programs almost always grow in sending frequency over time as you add more lifecycle touches. What starts as a 5-email onboarding sequence evolves into a comprehensive program with dozens of automated touchpoints. Loops' unlimited sending model provides cost predictability as your email program matures, while Brevo's per-email model creates cost uncertainty as volume grows.
