How it works

Three steps, from upload to download

No formatting or cleanup needed before you start.

  1. 01

    Upload your CSV

    Drop in an export from your CRM, lead tool or spreadsheet, up to 50 MB. Commas, semicolons and tabs all work.

  2. 02

    We find the email column

    Any column named email, e-mail, email address or mail is picked up for you. Duplicates are removed and not charged.

  3. 03

    Download the results

    Your columns stay as they were, with Result, Reason, Reason code and Suggestion added.

Download

Download exactly the rows you need

Take only the Deliverable rows, or the full list with every row's category. Both keep your original columns, as CSV or JSON.

Deliverable

Ready to send

Download Deliverable rows only and upload them straight to your sending tool.

Risky

Review first

Risky rows come with their reason, so you can decide per row.

Undeliverable

Suppression list

Filter the full list to Undeliverable rows and block them in your CRM or sending tool.

Processing

Nothing to chase

Slow servers are part of the job. The file is ready when every row has its final result.

Results

Three results. Every one comes with a reason.

No scores to decode. Each address is Deliverable, Risky or Undeliverable, and the reason says exactly what we found. Slow servers show Processing until the answer arrives.

Deliverable

The mail server confirmed the mailbox exists.

[email protected]The mailbox exists and accepts mail.
What to doSend.
Risky

It may deliver, but we can't promise it.

[email protected]The domain accepts mail for any address, so this mailbox can't be confirmed.
What to doRead the reason, then decide.
Undeliverable

Mail to this address will bounce.

[email protected]Possible typo. Did you mean [email protected]?
What to doRemove it or fix the typo.
Processing

The mail server is slow to answer. We're still asking.

[email protected]Still checking this mailbox.
What to doWait. The final result follows, with no second credit.
