Resend Alternative: Why EU Companies Are Switching to Truncus

If you're evaluating transactional email providers and need EU data residency, here's what you need to know.

The Problem with US-Based Email Infrastructure

Most transactional email providers—Resend, SendGrid, Postmark—are US companies with US-based infrastructure. For EU companies, this creates three issues:

Data leaves the EU. Even with a DPA, your customer email addresses are processed in Virginia or Oregon.

GDPR compliance burden falls on you. You need Standard Contractual Clauses, Transfer Impact Assessments, and ongoing monitoring.

Latency. Transatlantic round-trips add 100-150ms to every API call.

What to Look for in a Resend Alternative

When evaluating alternatives, prioritize:

1. EU data residency — Data stored and processed in EU, not just "GDPR compliant"
2. Equivalent developer experience — Similar API, SDKs, webhook support
3. Competitive pricing — No premium for EU hosting
4. Proven deliverability — 99%+ inbox placement

When Resend Is Still the Right Choice

Resend is excellent if:

• Your company is US-based with primarily US customers
• You're already integrated and migration cost is high
• You don't handle EU personal data

When to Choose Truncus

Truncus is the better choice if:

• You're an EU company or have EU customers
• You want true data residency, not just compliance paperwork
• You're building AI-native applications (MCP support)
• You want lower costs at scale

Migrating from Resend to Truncus

The APIs are similar. Migration typically takes under an hour:

1. Install the SDK

npm install @truncus/node

2. Update your client

// Before (Resend)
import { Resend } from 'resend';
const resend = new Resend(process.env.RESEND_API_KEY);

// After (Truncus)
import { Truncus } from '@truncus/node';
const truncus = new Truncus(process.env.TRUNCUS_API_KEY);

3. Send emails (identical interface)

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

4. Update webhook endpoints

Point your webhook URL to Truncus. Event payloads are similar.
