Migma vs Resend

Overview

Migma and Resend are both developer-focused email platforms, but they solve fundamentally different problems. Resend is a transactional email delivery API — you write the HTML, they send it. Migma is an AI-powered email platform that generates, validates, previews, and sends emails — all from a single API.

Migma

AI email generation + delivery + validation + previews in one API. Import your brand, describe what you want, get production-ready email HTML — then send it.

Resend

Email delivery API. You provide the HTML (or React Email components), they handle DKIM/SPF and deliver it to inboxes.

What You Get for the Price

The pricing models reflect the different value propositions: Resend at $20/mo gives you:

Email delivery API (you provide the HTML)
50,000 sends
React Email support
Basic contact management

Migma at $34.99/mo gives you everything Resend offers, plus:

AI-powered email generation (20 emails/day)
Automatic brand import from any website
Email validation (compatibility, links, spelling, deliverability)
Device previews on 20+ real devices
Export to Klaviyo, Mailchimp, HubSpot, MJML, PDF
Full audience management (tags, segments, topics, preference center)
AI image generation
CLI and MCP server for AI-assisted workflows

At Migma’s Basic tier, you’re paying $15/mo more than Resend Pro — but you get AI email generation, validation, previews, and multi-platform export included. With Resend, you’d need separate tools (and budgets) for each of those capabilities.

API Design & Code Examples

Both platforms use REST APIs with Bearer token auth and return JSON. Here’s how common workflows compare.

Authentication

Migma
Resend

import Migma from 'migma';

const migma = new Migma('sk_live_...');

API keys support granular permissions: audience:read, email:send, domain:write, etc.

import { Resend } from 'resend';

const resend = new Resend('re_...');

API keys are scoped to Full Access or Sending Access only.

Sending an Email

Migma
Resend

import Migma from 'migma';

const migma = new Migma('sk_live_...');

// Option 1: Send with your own HTML
await migma.sending.send({
  recipientType: 'email',
  recipientEmail: 'sarah@example.com',
  from: 'hello@yourbrand.com',
  fromName: 'Your Brand',
  subject: 'Welcome aboard!',
  template: '<html>Your HTML here</html>',
});

// Option 2: Generate with AI, then send
const email = await migma.emails.generateAndWait({
  projectId: 'proj_123',
  prompt: 'Create a welcome email for new subscribers',
});

await migma.sending.send({
  recipientType: 'email',
  recipientEmail: 'sarah@example.com',
  from: 'hello@yourbrand.com',
  fromName: 'Your Brand',
  subject: email.data.result.subject,
  conversationId: email.data.conversationId,
});

import { Resend } from 'resend';

const resend = new Resend('re_...');

// You must provide the HTML yourself
const { data, error } = await resend.emails.send({
  from: 'Your Brand <hello@yourbrand.com>',
  to: ['sarah@example.com'],
  subject: 'Welcome aboard!',
  html: '<html>Your HTML here</html>',
});

★ Insight ─────────────────────────────────────

Key difference: With Resend, you always bring your own HTML. With Migma, you can bring your own HTML or describe what you want and let AI generate it — on-brand, dark-mode optimized, and cross-client compatible.

─────────────────────────────────────────────────

Sending to a Segment

Migma
Resend

// Send to an entire audience segment
const { data } = await migma.sending.send({
  recipientType: 'segment',
  recipientId: 'seg_456',
  from: 'hello@yourbrand.com',
  fromName: 'Your Brand',
  subject: 'Summer Sale - 30% Off',
  conversationId: 'conv_789',
  topicId: 'topic_promotions', // preference center
});

// Track batch delivery
const status = await migma.sending.getBatchStatus(data.batchId);
console.log(`Sent: ${status.data.successCount}/${status.data.totalRecipients}`);

// Create a broadcast for the segment
const { data, error } = await resend.broadcasts.create({
  segmentId: 'seg_456',
  from: 'Your Brand <hello@yourbrand.com>',
  subject: 'Summer Sale - 30% Off',
  html: '<html>Your HTML here</html>',
  send: true, // send immediately
});

Contact Management

Migma
Resend

// Create a contact with tags
const { data } = await migma.contacts.create({
  email: 'steve@example.com',
  firstName: 'Steve',
  lastName: 'Smith',
  country: 'US',
  language: 'en',
  tags: ['premium', 'early-adopter'],
  customFields: { plan: 'enterprise', company: 'Acme' },
  projectId: 'proj_123',
});

// Bulk import (auto-async for >5000 contacts)
const { data: bulk } = await migma.contacts.bulkImport({
  projectId: 'proj_123',
  subscribers: contacts, // up to 100,000+
});

// List with cursor-based pagination
const { data: page } = await migma.contacts.list({
  projectId: 'proj_123',
  limit: 50,
  status: 'subscribed',
  tags: ['premium'],
});

// Create a contact
const { data, error } = await resend.contacts.create({
  email: 'steve@example.com',
  firstName: 'Steve',
  lastName: 'Smith',
  unsubscribed: false,
});

// List contacts (no filtering by tags or custom fields)
const { data: contacts } = await resend.contacts.list({
  audienceId: 'aud_123',
});

Error Handling

Both SDKs use the same { data, error } pattern — no try/catch needed:

Migma
Resend

const { data, error } = await migma.contacts.create({
  email: 'sarah@example.com',
  projectId: 'proj_123',
});

if (error) {
  console.error(error.code);       // 'validation_error'
  console.error(error.statusCode); // 400
  console.error(error.message);    // 'Email is required'
  return;
}

console.log(data.id); // TypeScript narrows — data is guaranteed non-null

const { data, error } = await resend.emails.send({
  from: 'hello@example.com',
  to: ['sarah@example.com'],
  subject: 'Hello',
  html: '<p>Hi</p>',
});

if (error) {
  console.error(error.name);    // 'validation_error'
  console.error(error.message); // 'Missing required field'
  return;
}

console.log(data.id);

What Migma Does That Resend Doesn’t

AI Email Generation

Describe what you want, get production-ready HTML:

const email = await migma.emails.generateAndWait({
  projectId: 'proj_123',
  prompt: 'Create a product launch email for our new wireless headphones. ' +
          'Highlight noise cancellation, 40-hour battery, and the $99 intro price.',
  languages: ['en', 'es'], // generate in multiple languages
});

// Returns complete, on-brand HTML — ready to send
console.log(email.data.result.subject); // "Introducing QuietMax Pro — $99 Launch Offer"
console.log(email.data.result.html);    // full responsive HTML with dark mode support

With Resend, you’d need to design and code the email yourself (or use a separate design tool), then pass the finished HTML to the API.

Brand Import

Import your brand identity from any website in one API call:

const brand = await migma.projects.importAndWait({
  urls: ['https://yourbrand.com']
});

// Automatically extracts: colors, typography, logos, tone of voice
// Every email generated after this matches your brand

Resend has no equivalent — you manually configure each email’s styling.

Email Validation

Test emails before sending — no third-party tools needed:

// Run all validation checks at once
const { data } = await migma.validation.all({
  conversationId: 'conv_789',
});

// Or run individually:
await migma.validation.compatibility({ conversationId: 'conv_789' }); // 20+ email clients
await migma.validation.links({ conversationId: 'conv_789' });         // broken link detection
await migma.validation.spelling({ conversationId: 'conv_789' });      // grammar & spelling
await migma.validation.deliverability({ conversationId: 'conv_789' }); // spam score analysis

Resend doesn’t offer validation. You’d need separate tools like Litmus or Email on Acid.

Device Previews

See how your email renders on 20+ real devices:

const preview = await migma.previews.createAndWait({
  conversationId: 'conv_789',
});

// Get screenshots for specific devices
const iphone = await migma.previews.getDevice(preview.data.previewId, 'iphone-15-pro');
const gmail = await migma.previews.getDevice(preview.data.previewId, 'gmail-dark');

Multi-Platform Export

Export to any email platform — not just HTML:

// Export to multiple formats from a single generation
await migma.export.html('conv_789');       // raw HTML
await migma.export.mjml('conv_789');       // MJML source
await migma.export.pdf('conv_789');        // PDF attachment
await migma.export.klaviyo('conv_789');    // Klaviyo-ready format
await migma.export.mailchimp('conv_789');  // Mailchimp template
await migma.export.hubspot({ conversationId: 'conv_789' }); // HubSpot

CLI & AI Tool Integration

# Generate from your terminal
migma generate --project proj_123 --prompt "Welcome email for new users"

# Send a test
migma send --to test@example.com --conversation conv_789

# Validate before sending
migma validate --conversation conv_789

Migma also ships an MCP server so you can use it directly from Claude Desktop, Cursor, Windsurf, and other AI tools.

What Resend Does That Migma Doesn’t

Wider SDK Support

Resend offers official SDKs in 9 languages:

Node.js

Python

Go

Ruby

PHP

Java

Rust

.NET

Elixir

Migma currently offers a Node.js/TypeScript SDK. If you work in Python, Go, or another language, you can use Migma’s REST API directly — or use Resend for the sending layer and Migma for generation.

SMTP Relay

Resend supports SMTP as an alternative to their REST API:

Host: smtp.resend.com
Port: 465 (TLS) or 587 (STARTTLS)
Username: resend
Password: re_your_api_key

Migma is REST API only — there’s no SMTP interface.

Inbound Email

Resend can receive emails on your domain, not just send them. This is useful for building support inboxes or email-based workflows.

Multi-Region Sending

Resend supports 4 sending regions (us-east-1, eu-west-1, sa-east-1, ap-northeast-1). Migma currently operates from a single region.

Using Them Together

Migma and Resend aren’t mutually exclusive. Migma supports Resend as a sending provider — use Migma for generation and validation, send through Resend:

import Migma from 'migma';

const migma = new Migma('sk_live_...');

// Generate the email with Migma's AI
const email = await migma.emails.generateAndWait({
  projectId: 'proj_123',
  prompt: 'Create a welcome email for new subscribers',
});

// Send through Resend (or SES, SendGrid, Mailgun)
await migma.sending.send({
  recipientType: 'email',
  recipientEmail: 'sarah@example.com',
  from: 'hello@yourbrand.com',
  fromName: 'Your Brand',
  subject: email.data.result.subject,
  conversationId: email.data.conversationId,
  providerType: 'resend', // use your connected Resend account
});

Connect your Resend account in Settings > Integrations > Email Service Providers to enable this workflow. See the ESP integration guide for details.
