A: Yes, it is possible. You can add a custom app script to your google sheet and the emails can be validated using our API through that script. However, the scraping speed won't be as fast as uploading it to our dashboad, because when someone upload a list on our dashboard, it get splited to multiple servers and get verified as fast as possible. Please contact us at support@reoon.com and we can provide you a demo script for that. You can modify the script based on your requirements. Have a great day.
