Verify an email list without writing code.

Find invalid and risky addresses before importing your list or sending a campaign. Upload a CSV or TXT file and download your original rows with verification results added.

1,000 free checks on your first project, once per account. No card required. Credits never expire.

Uses the public limit of 10 checks per hour.

Check your list in three steps.

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.

See which addresses need attention.

deliverable

The mail server accepted the address. Check the recommended action for risks that still need review. Acceptance does not guarantee delivery.

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.

Keep your columns and row order.

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.
