If all subscribers need to be removed from an Alertline on a regular basis an Alertline manager can setup a purge schedule. We advise that the purge is set to a time/date where its least likeliest to affect new users who are subscribing to the Alertline i.e you do not want to set a purge on a time/date when there will be a high volume of new subscribers signing up to the Alertline as the new subscribes would also be removed by the purge.
Here are steps on how to setup a purge schedule.
- Go to 'Communications' > 'Alertline' or press the Alertline icon on the Sentinel homepage.
- Select the ‘Manage’ button for the Alertline you wish to set a purge schedule for.
- Then select the button labelled ‘Purge Schedule’ in the ‘Actions’ section.
- The Purge Schedule modal view will appear.
- The following schedule options are available. Only one purge schedule option can be selected at any one time.
- No Schedule: Select this option if no schedule is required.
- Once: Select a date and time for when the subscribers should be removed. This schedule option will not repeat and will only be actioned once.
- Daily: Select a time for when the subscribers should be removed on a daily basis.
- Weekly: Select a day of the week and time for when the subscribers should be removed on a weekly basis.
- Monthly: Select a day of the month and a time for when the subscribers should be removed on a monthly basis. Its important to remember that not all months have the same number of days. If the 31st is chosen as the purge date, months with 30 days or less would need to use the ‘once’ schedule option.
- Once the schedule type has been selected, press the ‘Save’ button.
- On the manage Alertline page the Purge Schedule section will now show the selected purge option.
When a subscriber is purged from an Alertline the subscriber will not receive any new messages unless they resubscribe by scanning the QR code.
Note: The purge schedule uses UTC (Coordinated Universal Time). UTC does not change with the change of seasons, but local time may change if a time zone jurisdiction observes daylight saving time or summer time. For example when the clocks go forward by one hour in the UK (at the end of March), UTC will be one hour behind BST (British Summer Time) i.e. 10am BST would be 9am UTC but when the UK clocks go back one hour for winter time to GMT (Greenwich Mean Time) this means GMT and UTC will be the same times. Its important to factor in the above as during BST if you set a purge to happen at 14:00 UTC it would actually run at 15:00 BST but when the clocks go back an hour for winter (at the end of October) GMT and UTC align and the purge would run at 14:00. If you are unsure what the current time difference is between UTC, BST and GMT you can ask Google "What is the current time in UTC".
