  1. First create an account, then simply upload your CSV, Excel or other file containing email addresses in a single column by clicking +New > File Upload > Browse to select a file from your machine. You can zip your file to save time uploading.
  2. Next your file will automatically upload (and unzip if necessary). For exceptionally large files you'll see a loading bar while the file parses and loads.
  3. Once complete, click on the file name in your Library to view the file online. The viewer will open a spreadsheet in a new browser tab for viewing. Here you can apply the Email Verification Tools. Hit Enrichments > Gigasheet - Email Format & Alexa Rank and a dialog box will appear. Select the column containing the addresses you'd like to validate.
  4. Once you hit Apply, the enrichment will run and information about your email addresses will be added in new columns to the right of the original email column, highlighted in blue. Use Gigasheet to quickly filter, search, or create pivot tables. You can export your file as a CSV by clicking File > Export. A zipped CSV will appear in your Library for download.
