Verify an email list without writing code.

Upload a CSV or TXT file, choose the email column, and download the same rows with a result appended to each address.

Uses the public limit of 10 checks per hour.

From list to verified CSV.

The bulk tool runs in your account and keeps working after you close the page.

  1. 01

    Upload or paste

    Use a CSV with up to 100 columns, a TXT file, or a pasted list with one address per line.

  2. 02

    Confirm the cost

    Choose the email column and review unique addresses, duplicates, blank rows, and credits before starting.

  3. 03

    Download results

    Return later for the completed CSV. The result file stays available for seven days.

Four results, including unknown.

deliverable

The address passed the checks and its mail server accepted the mailbox.

undeliverable

A confirmed failure was found, such as invalid syntax, no usable mail server, or mailbox rejection.

risky

The address has a concrete risk signal such as a disposable provider or likely typo.

unknown

The checks could not confirm the mailbox. Review it instead of treating it as a failure.

What the download contains

Every original row stays in place. The output adds status, recommended action, flagged state, signals, and a typo suggestion when one is available. Duplicate addresses reuse the first result and blank rows remain blank.
