What information should my file contain for email validation?

For Verify to work effectively, your file must be saved in CSV (Comma-Separated Values) format. You can create a CSV file using tools like Microsoft Excel, Google Sheets, or by exporting from most database systems.

How to Structure Your CSV File:

To ensure fast and accurate processing, your CSV file should follow these simple rules:

1. Use a Single Header Column
Start your file with a header that clearly identifies the data.
For example: Email

2. List Only Email Addresses Under the Header

Below the header, include one email address per row.
Avoid adding names, phone numbers, or other information in the same file.

Example:

3. Save the File as CSV (Comma-Separated Values) format.

This format ensures compatibility with most platforms and validation tools. 

What should I do if I encounter issues uploading my file? 

If you experience any problems while uploading your file, here are a few steps you can take to resolve the issue:

1. Check your file format
   Make sure your file is saved as a CSV (Comma-Separated Values). Other formats like XLSX or TXT may cause upload errors.

2. Verify the structure of your file
   Ensure your CSV contains:

   • A single header (e.g., Email)

   • Only one column

   • One email address per row

   • No additional data, hidden columns, blank rows, or special characters

3. Check file size
   If your file is very large, try splitting it into smaller batches before uploading.

4. Re-save your file
   Sometimes re-saving the file as CSV from Excel or Google Sheets can fix hidden formatting issues.

5. Try a different browser or window
   Uploading the file using another browser, or in an incognito/private window, may resolve loading issues.
