Overview

Mailjet and Loops represent different generations of email platforms. Mailjet is a proven platform since 2010 with transactional and marketing combined at budget prices. Loops is a modern platform built specifically for SaaS with cleaner UX and event-based automation. See our Loops comparison for more alternatives.

Different Philosophies

Mailjet: Affordable email for everyone. Marketing teams, developers, SMBs. General-purpose with broad capabilities.

Loops: Modern email for SaaS. Event-based automation, user properties, product-focused workflows. Purpose-built for software companies.

This isn't about which is "better." It's about which philosophy matches your needs.

The SaaS Question

If you're building SaaS, Loops understands your world:

• Event-based automation triggers
• User lifecycle focus
• Modern API design
• Clean, uncluttered UX

Mailjet can do these things, but you configure them yourself. Loops is designed around SaaS patterns.

Pricing Difference

At 10,000 contacts:

• Mailjet: $35-50/month
• Loops: ~$99/month

Mailjet is roughly half the price. That's significant for bootstrapped startups. Loops includes unlimited sends and all features, which matters at scale.

Real-Time Collaboration

Mailjet's Passport editor is unique. Multiple people editing the same email simultaneously, like Google Docs. Loops doesn't have this. For teams with marketing/design collaboration, Passport is genuinely useful.

Platform Maturity

Mailjet: 15 years of operation, owned by Sinch (communications company), established infrastructure.

Loops: Newer company, rapidly growing, modern technology stack.

Both are reliable, but Mailjet has a longer track record.

Transactional Email

Both include transactional email. Mailjet has it built-in with mature API and SMTP. Loops includes transactional free with paid plans. Neither requires a separate product like Mailchimp/Mandrill.

For SaaS with Stripe

Neither platform has native Stripe integration. Mailjet requires third-party connections. Loops doesn't offer Stripe integration.

If you're SaaS with Stripe billing, consider Sequenzy. We combine SaaS focus (like Loops) with native Stripe integration at a better price point ($49 vs $99).

Making the Choice

Choose Mailjet for budget email with transactional support and real-time collaboration. Choose Loops for modern SaaS-focused platform with cleaner UX. For SaaS with Stripe, consider Sequenzy.

Generational Platform Differences

Mailjet represents the reliable incumbent. Built in 2010, battle-tested over 15 years, owned by a major communications company. You know what you are getting: solid email delivery with marketing features that work.

Loops represents the modern challenger. Built specifically for SaaS with contemporary design patterns and developer workflows. The interface is cleaner, the automation is more intuitive for software companies, and the pricing is simpler. But it lacks the track record and feature maturity that comes with time.

Event-Based vs Campaign-Based Automation

Loops treats product events as first-class citizens. User signs up, user activates feature, user upgrades plan. These events drive automated workflows naturally. Mailjet can handle events through its API but the automation builder is not designed around product events as a core concept.

For SaaS companies where user behavior drives communication strategy, Loops' event-first approach reduces the configuration needed to build meaningful automated sequences. For businesses with campaign-driven marketing, Mailjet's approach is more natural.

The Stripe Integration Gap

Neither Mailjet nor Loops integrates natively with Stripe. For SaaS companies, this is a significant gap since subscription billing events are among the most important triggers for automated communication. Trial ending, payment failed, plan upgraded - these events demand immediate, automated responses.

Sequenzy fills this gap with native Stripe OAuth integration, enabling payment-triggered automation at $49/month. If Stripe events are central to your email strategy, this capability matters more than either platform's other features.

User Behavior Tracking

SaaS email marketing depends on understanding how users interact with your product. Mailjet and Loops track user events differently. The depth of behavioral data determines how targeted your email automation can be.

Event tracking, feature usage monitoring, and activity scoring help you identify which users need onboarding help, which are ready to upgrade, and which are at risk of churning. Compare how each platform ingests and acts on this behavioral data.

Trial and Onboarding Optimization

Converting trial users to paid customers is critical for SaaS growth. Mailjet and Loops handle onboarding email sequences differently. The ability to trigger emails based on specific product milestones creates more relevant communication.

Effective onboarding emails guide users to their activation moment. Compare how each platform lets you define milestones, segment by trial progress, and personalize onboarding content based on user behavior and plan type. For deeper billing integration, see Sequenzy's Stripe features.

Company-Level vs User-Level Communication

SaaS products often have multiple users within a single account. Mailjet and Loops handle company-level targeting differently. Being able to group users by organization and trigger emails based on account-level events is essential for B2B SaaS.

Consider how each platform manages company attributes, aggregate usage data, and role-based communication. The ability to send different onboarding emails to admins vs team members, or trigger expansion revenue emails based on company-level metrics, matters for B2B growth.
