Sequenzy vs Resend: Full Platform vs Modern Transactional

Overview

Sequenzy and Resend are both modern email platforms, but they serve different needs. Resend focuses purely on transactional email with exceptional developer experience. Sequenzy provides a unified platform combining transactional email, marketing automation, and native billing integrations.

Key Differences

Developer Experience

Resend has the best developer experience in the transactional email space. Clean API design, excellent documentation, and React Email for JSX-based templates. If you are a React developer, building email templates in JSX feels natural.

Sequenzy also provides a modern API with good SDKs, but the DX focus is broader. You get billing integrations and marketing automation alongside transactional sending.

Platform Scope

Resend intentionally stays focused on transactional email. No marketing features, no sequences, no automation. This focus makes them excellent at what they do, but you will need a second tool for marketing.

Sequenzy provides the full stack: transactional email, marketing automation, sequences, and native billing integrations. One platform handles password resets and onboarding campaigns.

React Email

Resend created React Email and integrates it natively. Build email templates using React components with TypeScript support, IDE previews, and component reuse.

Sequenzy uses more traditional templating. You can still use HTML with variables, but JSX templates require more setup.

Code Comparison

Sequenzy

import { Sequenzy } from '@sequenzy/sdk';

const sequenzy = new Sequenzy({ apiKey: process.env.SEQUENZY_API_KEY });

await sequenzy.send({
  to: 'user@example.com',
  template: 'password-reset',
  variables: { resetLink: 'https://...' }
});

Resend with React Email

import { Resend } from 'resend';
import { PasswordResetEmail } from '@/emails/password-reset';

const resend = new Resend(process.env.RESEND_API_KEY);

await resend.emails.send({
  from: 'noreply@example.com',
  to: 'user@example.com',
  subject: 'Reset your password',
  react: PasswordResetEmail({ resetLink: 'https://...' })
});

When to Choose Sequenzy

• You need both transactional and marketing email
• You use Stripe, Polar, Creem, or Dodo for billing
• You want to avoid managing multiple email services
• Revenue attribution matters for your email campaigns

When to Choose Resend

• You only need transactional email
• React Email and JSX templates are important
• You already have a separate marketing solution
• The free tier is valuable for your use case

The Bottom Line

Choose Sequenzy if you want a unified platform that handles transactional email alongside marketing automation with billing integrations. Fewer moving parts, one sender reputation.

Choose Resend if you want the best possible developer experience for transactional email and will handle marketing separately.
