Comparison

Veil Mail vs Postmark

Veil Mail is a modern alternative to Postmark that keeps its transactional focus — and adds marketing campaigns, automation sequences, PII protection, and CASL compliance.

Side-by-side: sending an email

Postmark

import { ServerClient } from 'postmark'

const client = new ServerClient('POSTMARK_SERVER_TOKEN')

await client.sendEmail({
  From: 'hello@yourdomain.com',
  To: 'user@example.com',
  Subject: 'Welcome!',
  HtmlBody: '<h1>Welcome</h1>',
})

Veil Mail

import { VeilMail } from '@resonia/veilmail-sdk'

const client = new VeilMail('veil_live_xxxxx')

await client.emails.send({
  from: 'hello@yourdomain.com',
  to: 'user@example.com',
  subject: 'Welcome!',
  html: '<h1>Welcome</h1>',
})

Feature comparison

What Veil Mail offers that Postmarkdoesn't

• Full marketing stack. Campaigns with A/B testing, automation sequences, and segmentation. Postmark offers basic broadcast streams without campaign tooling.
• Automatic PII protection. Every outgoing email is scanned for SSNs, credit cards, medical records, and other sensitive data before delivery.
• CASL & GDPR compliance. Consent tracking with expiry management, subscription topics, and compliant unsubscribe pages out of the box.
• React Email adapter. Postmark has no React Email integration. Veil Mail ships @resonia/react-email as a drop-in replacement for @react-email/render.
• Automation sequences. Drip campaigns with branching logic, delay steps, and audience-join triggers — not available in Postmark.
• Game engine SDKs. Official Unity, Unreal Engine, and TouchDesigner SDKs for in-game email flows.
