Loops Email Review 2026: The Email Platform Built for SaaS

Loops combines transactional email and marketing email in one platform. Built specifically for SaaS companies. After migrating from separate Resend + ConvertKit setups, here's the review.

What Loops Does

• Transactional email — welcome emails, password resets, receipts
• Marketing email — newsletters, drip campaigns, product updates
• Automations — event-triggered email sequences
• Contact management — user properties, segments, events
• API-first — TypeScript SDK, REST API, webhooks

What I Like

One Platform for Everything

Before Loops: Resend for transactional + ConvertKit for marketing = two platforms, two billings, two sets of contacts.

With Loops: one platform, one contact list, one API. Transactional and marketing email unified.

Developer-First API

import { LoopsClient } from 'loops'
const loops = new LoopsClient(process.env.LOOPS_API_KEY)

// Create/update contact
await loops.createContact({
  email: user.email,
  firstName: user.name,
  plan: 'pro',
  signupDate: new Date().toISOString(),
})

// Send transactional email
await loops.sendTransactionalEmail({
  transactionalId: 'clx_welcome',
  email: user.email,
  dataVariables: { name: user.name, loginUrl: '/dashboard' },
})

// Track event (triggers automations)
await loops.sendEvent({
  email: user.email,
  eventName: 'subscription_upgraded',
  eventProperties: { plan: 'pro', mrr: 29 },
})

Clean TypeScript SDK. Well-documented. Intuitive API design.

Event-Based Automations

Define automations triggered by user events in your app:

• user.signed_up → Welcome sequence (5 emails over 14 days)
• trial.ending → Trial conversion sequence
• subscription.cancelled → Win-back sequence
• user.inactive_7d → Re-engagement email

Design flows in the visual editor. Trigger from your app via API.

Beautiful Email Editor

Drag-and-drop email builder that produces clean, responsive HTML. Templates for SaaS (welcome, onboarding, changelog, receipts).

Pricing Is Fair

Cheaper than ConvertKit and Mailchimp at every subscriber count. Transactional email included — no separate Resend/Postmark bill.

What I Don't Like

No Landing Pages

ConvertKit has landing pages and forms. Loops has basic embeddable forms but no landing page builder. You'll need a separate tool for lead capture pages.

Smaller Template Library

Fewer pre-built templates than Mailchimp or ConvertKit. The templates that exist are good but limited in variety.

Newer Platform

Loops is younger than ConvertKit and Mailchimp. Fewer integrations, smaller community, less documentation from third parties.

No A/B Testing (Yet)

Basic A/B testing for subject lines exists but it's not as mature as Mailchimp's testing features.

Limited Segmentation

Segmentation is functional but not as advanced as Mailchimp's. Complex multi-condition segments require workarounds.

Pricing

Contacts	Price
1,000	Free
5,000	$49/mo
10,000	$79/mo
25,000	$159/mo
50,000	$299/mo

Includes transactional AND marketing email. Compare with Resend ($20/mo) + ConvertKit ($79/mo) = $99/mo for the same 5K contacts.

Best Use Cases

• SaaS companies — transactional + marketing in one tool
• Developer-led teams — API-first approach
• Product-led growth — event-based automation for user onboarding
• Startups — affordable, clean, focused

Worst Use Cases

• E-commerce — Mailchimp or Klaviyo have better e-commerce integrations
• Creators/bloggers — ConvertKit or beehiiv have better creator tools
• Enterprise — need advanced segmentation, compliance features
• Non-technical teams — API-first might be intimidating

FAQ

Can Loops replace Resend?

Yes. Loops handles transactional email with the same quality. One less service to manage.

Is Loops reliable for transactional email?

Yes. High deliverability, fast sending. Suitable for password resets and time-sensitive notifications.

Can non-developers use Loops?

Yes, for campaign creation and automation design. The visual editor is intuitive. But integration with your app requires a developer.

Bottom Line

Loops is the best email platform for SaaS companies in 2026. Transactional + marketing in one tool, developer-first API, fair pricing. The tradeoff is fewer features than Mailchimp and fewer creator tools than ConvertKit. If you're building a SaaS, Loops should be your first choice for email.
