Can I cancel a bulk verification that is already running?

Right now, Valid Email Checker does not offer a cancel button for a bulk verification task once you have started it. After the task hits the Processing state, the verification engine runs through every address you submitted and writes results back to your account. The only way to stop a running task is to wait for it to finish.

Why there is no cancel control

Two reasons. First, the credits are deducted at task creation, not at the end. So a "cancel" button would have to handle a partial refund, which is a complex billing event — we would need to settle how many addresses had already been verified, refund the rest, and reconcile against any partial download you might have started. Second, the verification engine batches your addresses across multiple chunks running in parallel; pausing them mid-flight risks leaving the dataset in an inconsistent state.

What you can do if you uploaded the wrong list

If you started a task by mistake (wrong list, accidental click, duplicate of another task already running), the best path is:

1. Let the task complete. It will keep running regardless.
2. On the Uploads & Results page, find the task and delete it after completion — the trash icon next to the View Results button removes the entry and its results from your account.
3. If the situation warrants a credit refund (you uploaded the same list twice in a row, you uploaded a test file by accident), contact support with the task ID. We review case-by-case and credit back what we reasonably can.

Tasks that fail on their own

Different from manual cancellation, a task can fail automatically if our verification provider returns a hard error on every chunk or if a partial-failure threshold is crossed. In those cases we automatically refund the credits for the unverified portion and mark the task with a "Partial failure" indicator on the task status badge. You see the refund as a separate row in your Credits History.

What will not stop a task

• Closing your browser tab — the task is on our backend, not your browser.
• Logging out — same reason, the task keeps running on the server.
• Deleting the task row from Uploads & Results — the delete button is disabled while status is Processing precisely for this reason.
• Refreshing the dashboard — refreshes are purely client-side.
