I have created the site workflow and make it as schedule workflow when the schedule is over than also its not firing for emails for the items which I have created
Are you able to trigger it manually? If so, the scheduled time in your site collection will be different from that of the Nintex configured time in the Central Administration.
So please get that information and make changes to your site collection time zone accordingly. Hope the info helps!
So the scheduled site workflow is successful? Just the email notifications are not working? If you go to Site Contents, and then Site Workflows, you can manually run the workflow there, or click on a previously run workflow to see more information. Is there any more information in there that might guide us?
