We are migrating from one different ticketing system to Jira service management, so while performing migration we want to keep the notification off and once the migration is done, we want to send out invitation emails to all the customers which are around 5000
I have searched over community I did not found any way yet to resend in a bulk because one by one sending emails notification to existing customers seems not feasible at this moment
Can you please suggest how it should be done?
