Use case

Temporary email for QA testing signup flows

Every signup test needs an address nobody else has used. Temporary inboxes give each test run its own, and let you assert on the email the product actually sent.

The problem with shared test mailboxes

A single shared QA inbox fills with old messages, and two parallel runs read each other's codes. The failures look random and take hours to track down.

A new address per test removes the shared state completely: whatever lands in that inbox belongs to that run.

What to assert on

The email arrives within your delivery budget (seconds, not minutes).
The subject, sender and link target are correct for the environment under test.
The verification code or link works once and fails the second time.
Expired codes are rejected and a resend invalidates the previous one.

Doing it with Emailsify

In the browser, open the inbox, use the address in your form and watch the message arrive. For automated runs, an AI agent or script harness can use the Emailsify MCP server: create an address, trigger the signup, then wait for the code.

1. create inbox               -> qa.run482@emailsify.com
2. (your test submits the signup form with that address)
3. wait for the code         -> 482913

Keep the data tidy

Mail expires 2 hours after it arrives, so there is nothing to clean up. If you assert on content, read it in the same run; do not rely on it being there tomorrow.

Frequently asked questions

Can I run many tests in parallel?

Yes. Generate a separate address for every test so no two runs ever share an inbox.

How long does the email take to arrive?

Usually a few seconds after the sending service hands it over. The sender controls most of that delay.

Does it work for password-reset testing?

Yes, any email sent to the address appears in its inbox, so reset links and codes can be tested the same way.
