Overview

Selzy and Loops serve different audiences entirely. For our take on each, see our Selzy comparison and Loops comparison.

Loops for SaaS

Loops is built specifically for SaaS. Event-driven architecture, transactional + marketing email combined, clean developer API, and a modern UI. If you're building a SaaS product and want email that understands your users' behavior, Loops is purpose-built for that.

Selzy for General Marketing

Selzy is a traditional email marketing tool with AI superpowers. For general businesses that need marketing campaigns, Selzy's AI tools help create content faster at a lower price. It's not built for SaaS, but it handles marketing email well.

The Sequenzy Alternative

For SaaS founders who want native Stripe integration with their email, Sequenzy combines transactional email and marketing campaigns with Stripe integration at $49/month.

Two Different Worlds of Email

Selzy and Loops barely compete with each other because they solve fundamentally different problems. Selzy helps marketing teams send campaigns to subscriber lists. Loops helps product teams send behavior-triggered messages to users. The overlap is minimal.

A Selzy workflow looks like: create email with AI, select a segment, schedule send, review metrics. A Loops workflow looks like: define event triggers, map user properties, build conditional logic, send transactional and marketing messages based on user behavior.

If you are debating between these two platforms, the first question to answer is whether your email needs are marketing-driven or product-driven. If marketing, choose Selzy. If product, choose Loops. If both, consider a platform like Sequenzy that bridges the gap.

The Transactional Email Divide

Loops combines transactional email and marketing email in one platform. Password resets, onboarding sequences, notification emails, and marketing campaigns all sent from the same system with unified analytics. This eliminates the need for separate transactional services like SendGrid or Postmark.

Selzy is marketing-only. If your business sends transactional emails, you need a second platform alongside Selzy. Running two email platforms means two sets of analytics, two sender reputations to manage, and two systems to maintain. The combined cost often exceeds what Loops charges for everything in one.

For SaaS companies, transactional email is not optional. Users expect password resets, account notifications, and billing confirmations to arrive instantly and reliably. Having these messages in the same system as your marketing email simplifies infrastructure and ensures consistent deliverability across all email types.

Developer Experience Comparison

Loops appeals to developer-founders with a clean, modern API, good documentation, and a product-first approach. Setting up event tracking, configuring automation triggers, and managing user properties feels natural for anyone comfortable with code.

Selzy is built for non-technical marketers. Point-and-click interface, AI-generated content, drag-and-drop email builder. No code required. This accessibility is valuable for teams without developer resources but means the platform cannot access the behavioral data that powers sophisticated automation.

The developer experience question reflects a broader organizational question. Companies with engineering resources can leverage Loops' event-driven architecture. Companies without developers can use Selzy's AI tools to create and send marketing campaigns. Match the platform to your team's capabilities, not just your aspirations.
