Email Validation

How to use this page

1. 1

   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.

2. 2

   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.

3. 3

   Start validation

   Click Validate N unique emails after reviewing the credit preview. Only unique, nonblank, correctly shaped addresses are submitted. On a self-serve plan, the preview instead shows your daily email checks, shared with contacts checked before sending, and how many are left in the last 24 hours. If the file has more unique emails than are left, the button is disabled and the page asks you to split the file or try again later. Recent results for the same client and the same normalized set of addresses can be reused without additional validation credits, even when CSV row order or other columns changed. The revised output preserves your uploaded rows and columns. Reuse requires complete readable results validated within seven days and retains the original validation date. The summary band counts excluded rows from completed lists as Credits saved.

4. 4

   Monitor the job and download results

   Watch Validation history for Validating, Preparing download, Complete, Failed or Needs review. Needs review means the upload was not confirmed and may already have started. Contact support before uploading the list again. If the result download is empty, unreadable or incomplete, the job stays active while SalesHive checks the original submission again. Wait for Complete rather than uploading the list again. A completed job shows Valid, Catch-all, Invalid and Unknown totals. Select 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.

What the buttons do

Choose CSV

Selects a CSV file up to 15 MB for local analysis before validation credits are used. After a file is selected, the same control reads Choose another.

Email column

Selects which CSV column contains the addresses when automatic header detection does not choose the right column.

Validate unique emails

Submits the exact unique, valid email count shown in the credit preview for validation. On a self-serve plan it is disabled when the file has more unique emails than the checks left today.

Validation history

Shows progress, verdict totals, errors and completed jobs for the selected client. Needs review identifies an unconfirmed upload that support must check before you retry.

Download results

Downloads the original CSV rows with validation status, safe-to-send, and validation timestamp columns.
