Hi David,
I'd be happy to help you with this issue.
In order to help us better troubleshoot, can you let us know a) Which email client you are using, and b) Which email provider you are using?
Also, do you know how long you are waiting to send an email after uploading new flights to your account? Sometimes, it may take a few minutes for the badge to update.
Thank you. We will follow up as soon as we hear back from you regarding your email client and provider.
Best regards,
Tom
