Every email tells a story. Most tools only show you the ending.
We’re building Kurrier to make email observable—not just deliverable.
Email has become critical infrastructure
Whether you’re running a SaaS product, an ecommerce store, a bank, or an internal platform, email is one of the most important parts of your application.
Password resets.
Invoices.
Deployment notifications.
Security alerts.
Support conversations.
Authentication codes.
Every one of these depends on email working correctly.
Yet when something goes wrong, most teams end up jumping between multiple tools trying to answer one simple question:
What actually happened to this email?
The current workflow is broken
A missing email usually sends developers and support teams down a rabbit hole.
You might check:
- your application logs
- your SMTP provider
- SES or Mailgun dashboards
- raw email source
- message headers
- SPF/DKIM/DMARC
- customer support tickets
- Slack conversations
- browser email clients
Each tool answers a small piece of the puzzle.
None of them tell the complete story.
We think email deserves observability
Infrastructure teams have observability.
Applications have observability.
Databases have observability.
Email rarely does.
Instead of simply showing that an email was “sent,” we want to answer questions like:
- What did the recipient actually receive?
- Which SMTP server handled the message?
- Which route did it take?
- Did authentication pass?
- Was it delayed?
- Was it modified?
- Why did it bounce?
- Who investigated it?
- Was it replayed?
Introducing Kurrier IO
Kurrier started as a collaborative email workspace.
That foundation is still there.
But over the past year we’ve been building something much larger.
Kurrier IO is becoming a workspace for understanding every email.
Instead of switching between five different dashboards, you can inspect everything in one place.
For every message you can view:
- Rendered preview
- HTML
- Plain text
- Raw source
- Headers
- SMTP metadata
- Structured JSON
- Delivery timeline
- Attachments
- Team activity
Built on top of your existing providers
Kurrier isn’t another email provider.
It doesn’t ask you to migrate.
Whether you use:
- Amazon SES
- Mailgun
- Postmark
- SMTP
- Google Workspace
Kurrier works alongside your existing infrastructure.
Your providers stay exactly where they are.
Kurrier simply provides the visibility and tooling that has traditionally been missing.
Built for the people who solve email problems
Kurrier is designed for:
- Developers
- Support engineers
- Platform teams
- DevOps
- Customer support
- Email operations
The people who are asked:
“The customer didn’t receive the email.”
Collaboration when you need it
Sometimes investigating an email is a solo task.
Sometimes it becomes a team effort.
That’s why Kurrier also includes:
- Assignments
- Priorities
- Internal comments
- Activity history
- APIs
- Webhooks
- Automation
Because understanding an email is only half the job.
The other half is resolving the issue.
This is just the beginning
Over the coming months we’ll continue expanding Kurrier’s observability capabilities with richer delivery diagnostics, identity and provider health, replay tooling, and more ways to understand the journey every email takes.
We believe email deserves first-class tooling.
And we’re excited to share what we’re building.
