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

#showdev #sideprojects #testing #tooling

Hey Dev.to 👋

I just launched tempinbox.dev and I’d love feedback from developers, QA folks, and anyone who regularly tests signup / OTP / verification flows.

What it is

Tempinbox is a temporary email service for low-risk workflows like:

  • trial signups
  • testing registration flows
  • OTP / verification checks
  • reducing spam in your personal inbox

The main idea is simple: instead of a single throwaway inbox, you can use up to 3 workflow inboxes in one browser and switch between them.

Why I built it

A lot of temp email tools are optimized for “one quick address, then done.”

I wanted something better for actual workflows:

  • testing multiple accounts
  • keeping trial signups separate
  • switching between inboxes without losing context

Key features (current)

  • Create up to 3 inboxes in one browser
  • Inboxes are browser-persisted (until you delete them, clear browser data, or 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

Important note (proper use)

This is best for low-risk signups/testing/short-term verification.

Please don’t use temporary email for critical accounts like:

  • banking
  • healthcare
  • legal
  • payroll / tax
  • anything recovery-critical

For those, use your personal authenticated email.

Built with

I built this on the Cloudflare stack (Workers / Pages-based setup) and focused on keeping the UX straightforward for real testing workflows.

I’d really like feedback on

  1. UX clarity

    Is it obvious how to create/switch/manage multiple inboxes?

  2. Developer/QA usefulness

    Does the 3-inbox workflow actually help in testing flows?

  3. Friction vs abuse protection

    Is the Security Check experience reasonable?

  4. Email viewing experience

    Anything confusing in reading messages / refreshing / clearing inboxes?

  5. Feature requests

    What would make this genuinely useful for your workflow?

Try it

If you test it, I’d really appreciate:

  • a short comment with your use case
  • any rough edges / bugs
  • one feature you’d want next

Thanks in advance for taking a look.
