notification emails about due dates

[Isaac Myman]

Is there a way to send out notification emails to the assignee of the ticket 3 days before the due date of that ticket and then again on the due date of that ticket? We use the JIRA cloud instance so the Notification Helper add on won't work for us.

You can do it by creating a subscription. Create a filter that shows issues that has 3 days before the due date. Specify currentUser() as assignee. Another and simpler way to do it is using a Issue Reminders JIRA Plugin.  It has a global due date reminder setting.

We use the cloud instance of Jira though not the Server instance. That plugin is only available for server instance

We've developed a cloud plugin that can do that. Simply define 2 messengers with email channels and specify jql as dueDate = "+3d" and another as dueDate during (now(), +1d). Check out: https://marketplace.atlassian.com/plugins/net.vacom.jirassimo
