I launched Tempinbox.dev (temporary email with up to 3 workflow inboxes)

Source: Dev.to

Overview

I just launched tempinbox.dev, a temporary email service aimed at developers, QA engineers, and anyone who regularly tests signup, OTP, or verification flows.

What It’s For

• Trial sign‑ups
• Testing registration flows
• OTP / verification checks
• Reducing spam in your personal inbox

How It Works

Instead of a single throwaway inbox, you can create up to three workflow inboxes in the same browser and switch between them.

• Inboxes are persisted in the browser (until you delete them, clear browser data, or a cleanup policy removes old data).
• Quick actions in the UI:
  • Generate New Email
  • Copy
  • Show QR Code
  • Refresh
  • Clear Inbox
  • Switch Address
  • Delete

A security check may appear before address creation when protection is enabled.

When Not to Use

Avoid temporary email for critical accounts such as:

• Banking
• Healthcare
• Legal
• Payroll / tax
• Any recovery‑critical service

For those, use a personal authenticated email.

Technical Stack

Built on the Cloudflare stack (Workers / Pages) with a focus on a straightforward UX for real testing workflows.
