Overview
Use Contacts > Email Validation to check a cleaned prospect CSV before outreach. The page stays scoped to the selected client, previews unique valid addresses and excluded rows before validation credits are used, tracks the asynchronous job, shows credits saved across completed lists, and provides a merged result file with a verdict on every original row.
How to use this page
Select the client and open Email Validation
Choose the client from the switcher, then open Platform > Contacts > Email Validation. Validation jobs, credit counts, and result files stay scoped to that client. If no client is selected, choose one before uploading.
Upload and preview a cleaned CSV
Drop a CSV into the upload area or click Choose CSV. Files can be up to 15 MB and must contain a header row plus at least one data row. The page detects common email headers, or you can choose the email column manually. Review total rows, unique emails to validate, duplicates skipped, and blank or malformed rows skipped before using credits.
Start validation
Click Validate N unique emails after reviewing the credit preview. Only unique, nonblank, correctly shaped email addresses are submitted. The page prevents duplicate charges when the exact file and email column were already submitted for the client within the recent reuse window. The summary band counts excluded rows from completed lists as Credits saved.
Monitor the job and download results
Watch Validation history for progress, completion, or failure. A completed job shows Valid, Catch-all, Invalid, and Unknown totals. Click Download results to get the original rows with validation status, safe-to-send, and timestamp columns. Completed files also appear in the client Agents Files tab.
