Mission Inbox vs. Resend
Resend is a modern developer API with great UX — but it's an AWS SES wrapper that explicitly bans cold email. Mission Inbox owns its infrastructure, is built for outreach, and scales to 100M+ emails without AWS limits.
Feature Comparison
Feature | Mission Inbox | Resend |
|---|---|---|
Cold Email Policy | Outreach-Friendly | Banned & Suspended |
Infrastructure | Isolated Servers | Shared AWS SES |
AI Protection | MI Shield™ Included | None |
Scale Capability | 100M+ Emails | Limited by AWS |
Resend's Limitations
Beautiful DX, Wrong Use Case
Resend offers a modern, React-friendly API for transactional emails. Great for SaaS notifications — but built entirely on AWS SES shared infrastructure with strict compliance rules against cold email.
Cold Email Prohibited
Resend's ToS explicitly bans "unsolicited commercial emails." Cold outreach violates their policy.
Built on AWS SES
Resend is a wrapper around AWS SES. Users inherit all of SES's limitations: shared IPs, volume limits, compliance rules, and no control over infrastructure.
Shared Infrastructure
No dedicated IPs. All users share AWS SES sending pools, creating shared reputation risk.
How Mission Inbox Differs
Outreach-Friendly Policy
Mission Inbox is built for cold email outreach. No policy violations, no bans, no restrictions.
Owned Infrastructure
Mission Inbox operates its own servers and dedicated IPs. Not a reseller of AWS or any third party.
MI Shield™ AI Protection
Every email is scanned by MI Shield before sending. Proactive domain protection.
Unlimited Scale
Scale from 1K to 100M+ emails without hitting AWS SES limits.
When to Choose Each
Use Case | Choose |
|---|---|
Modern SaaS transactional email | Either works |
Cold email outreach | Mission Inbox only |
Marketing campaigns | Mission Inbox |
Unlimited scale | Mission Inbox |
React/Next.js developer experience | Resend (for transactional only) |
