"Please Configure your Email Account in Settings": Do you want to send your Scans via Email and keep receiving an error message?
Scanbot always tries to send emails with the default native iOS Mail app. Please note that this app has to be configured in the settings of your native 'Mail' app on your iPhone if you have not done so before.
Just open the Mail app and add your email account. Afterward, you can use Scanbot to send your documents via email.
Other emailing apps, can be used by choosing the 'Share' functionality.
