AI email generation + delivery + validation + previews in one API. Import your brand, describe what you want, get production-ready email HTML — then send it. Email delivery API. You provide the HTML, they handle DKIM/SPF and deliver it to inboxes. *** ## Quick Comparison | Feature | Migma | Resend | | ----------------------- | --------------------------------------------------- | -------------------------------------------------------- | | **AI email generation** | Prompt-to-email with brand awareness | No | | **Email sending** | Built-in + SES, SendGrid, Mailgun, Resend | Built-in only | | **Contact management** | Full CRM (tags, segments, topics, bulk import) | Basic (contacts + segments) | | **Email validation** | Compatibility, links, spelling, deliverability | No | | **Device previews** | 20+ real devices | No | | **Export formats** | HTML, MJML, PDF, PNG, Klaviyo, Mailchimp, HubSpot | HTML only | | **Brand import** | Auto-import from any website (colors, fonts, logos) | No | | **Webhooks** | HMAC-signed with delivery history | HMAC-signed with retry | | **Broadcast/campaigns** | Send to segments, tags, topics | Send to segments (Broadcasts) | | **Node.js SDK** | Yes (`migma`) | Yes (`resend`) | | **SDK languages** | Node.js/TypeScript | Node.js, Python, Go, Ruby, PHP, Java, Rust, .NET, Elixir | | **CLI** | Yes (`@migma/cli`) | No | | **MCP server** | Yes (Claude, Cursor, etc.) | No | | **Managed domains** | Instant (no DNS setup) | No | | **Inbound email** | No | Yes | | **SMTP relay** | No | Yes | | **Multi-region** | Single region | 4 regions | *** ## Pricing ### Migma Plans Migma offers two paid plans (both include a **7-day free trial** when you first subscribe): | Plan | Price | AI Emails/Day | Sending/Month | Projects | | ------------ | ---------- | ------------- | ------------- | --------- | | **Premium** | \$99.99/mo | 100 | 200,000 | Unlimited | | **Business** | \$299/mo | Unlimited | 3,000,000 | Unlimited | Annual billing saves up to 23%: Premium at $950/year, Business at $2,748/year. ### Resend Plans | Plan | Price | Emails/Month | Overage | Domains | Webhooks | | -------------- | ------- | --------------- | ------------ | -------- | ------------ | | **Free** | \$0 | 3,000 (100/day) | N/A | 1 | 1 endpoint | | **Pro** | \$20/mo | 50,000 | \$0.90/1,000 | 10 | 10 endpoints | | **Scale** | \$90/mo | 100,000 | \$0.90/1,000 | 1,000 | 10 endpoints | | **Enterprise** | Custom | Custom | Custom | Flexible | Flexible | ### 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 * Basic contact management **Migma at \$99.99/mo** gives you everything Resend offers, plus: * AI-powered email generation (100 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 & GIF generation * CLI and MCP server for AI-assisted workflows Migma's Premium plan includes AI email generation, validation, previews, and multi-platform export — capabilities you'd need to piece together from multiple separate tools with Resend. *** ## API Design & Code Examples Both platforms use REST APIs with Bearer token auth and return JSON. Here's how common workflows compare. ### Authentication ```typescript theme={null} import Migma from 'migma'; const migma = new Migma('sk_live_...'); ``` API keys support granular permissions: `audience:read`, `email:send`, `domain:write`, etc. ```typescript theme={null} import { Resend } from 'resend'; const resend = new Resend('re_...'); ``` API keys are scoped to Full Access or Sending Access only. ### Sending an Email ```typescript theme={null} import Migma from 'migma'; const migma = new Migma('sk_live_...'); // Option 1: Send a selected Migma email slot await migma.sending.send({ recipientType: 'email', recipientEmail: 'sarah@example.com', from: 'hello@yourbrand.com', fromName: 'Your Brand', subject: 'Welcome aboard!', emailId: 'email_123', }); // 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, }); ``` ```typescript theme={null} 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 ', to: ['sarah@example.com'], subject: 'Welcome aboard!', html: 'Your HTML here', }); ``` `★ Insight ─────────────────────────────────────` **Key difference**: With Resend, you bring your own HTML. With Migma, you can pick a generated email by `emailId` or describe what you want and let AI generate it — on-brand, dark-mode optimized, and cross-client compatible. `─────────────────────────────────────────────────` ### Sending to a Segment ```typescript theme={null} // 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', emailId: 'email_123', 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}`); ``` ```typescript theme={null} // Create a broadcast for the segment const { data, error } = await resend.broadcasts.create({ segmentId: 'seg_456', from: 'Your Brand ', subject: 'Summer Sale - 30% Off', html: 'Your HTML here', send: true, // send immediately }); ``` ### Contact Management ```typescript theme={null} // 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'], }); ``` ```typescript theme={null} // 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: ```typescript theme={null} 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 ``` ```typescript theme={null} const { data, error } = await resend.emails.send({ from: 'hello@example.com', to: ['sarah@example.com'], subject: 'Hello', html: '

Hi

', }); 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: ```typescript theme={null} 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: ```typescript theme={null} 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: ```typescript theme={null} // 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: ```typescript theme={null} 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: ```typescript theme={null} // 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 ```bash theme={null} # 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 [MCP](/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: 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: ```typescript theme={null} 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](/integrations/email-service-providers) for details. *** ## When to Choose Migma You want AI to generate on-brand emails from a text prompt You need email validation, previews, and deliverability testing built in You want to export to Klaviyo, Mailchimp, HubSpot, or MJML You want a CLI and MCP server for AI-assisted workflows You need full audience management (tags, segments, topics, preference center) You want instant sending domains with no DNS setup ## When to Choose Resend You only need transactional email delivery (you already have the HTML) You need SDKs in Python, Go, Ruby, PHP, Java, Rust, or .NET You need SMTP relay support You need inbound email (receiving emails) You need multi-region sending for data residency compliance *** ## Summary | | Migma | Resend | | --------------------- | ----------------------------------------------------------------------------- | ------------------------------------------------------------------------- | | **Best for** | Teams that want AI to handle email creation, testing, and delivery end-to-end | Developers who build their own email templates and need reliable delivery | | **Starting price** | \$99.99/mo (Premium) | \$20/mo (Pro) | | **Trial / free tier** | 7-day trial on Premium or Business | 3,000 emails/month, 100/day | | **Core strength** | AI generation + validation + previews + multi-platform export | Fast, reliable email delivery with great DX | | **API endpoints** | 51+ | \~25 | | **SDK resources** | 14 resource classes | \~8 resource classes | *** ## Get Started Start with a 7-day trial on Premium or Business Import your brand and send your first email in 5 minutes Full Node.js SDK documentation with all 14 resources Complete endpoint documentation
