Stock rules warn you when stock runs low. Each rule's timing setting decides when Shuttle emails you about the alerts that rule raises. Choose Real-time to hear about low stock straight away, or Fixed-time to get alerts together once a day.
When does a Real-time rule email you?
A stock rule set to Real-time emails you as soon as an order brings stock down to the rule's threshold. Choose Real-time when you want to react to low stock straight away.
When does a Fixed-time rule email you?
A stock rule set to Fixed-time collects its alerts and sends them once a day, at the time you choose. Choose Fixed-time when you prefer to review stock alerts in one go.
How fixed-time alerts reach you depends on the Send me a daily summary of stock alerts setting:
With the daily summary on, which is the default, fixed-time alerts don't get their own email. They go into your daily summary instead, which covers every alert from the past day and comes with a CSV file. Shuttle skips the summary on days with no alerts.
With the daily summary off, each fixed-time rule sends its own email at your chosen time.
Choose when fixed-time alerts arrive
You set the delivery time for fixed-time alerts and the daily summary in your notification settings.
In Shuttle, go to Settings > Alerts & Notifications.
Under Fixed time delivery, choose your Time zone and Preferred time.
Click Save.
Shuttle fills in a time zone if you haven't saved one. When you open Settings > Alerts & Notifications with no time zone saved, Shuttle saves your browser's time zone for you. Until a time zone is saved, Shuttle uses your Shopify store's time zone for fixed-time alerts and daily summaries.
Change a stock rule's timing
You can switch a global rule between real-time and fixed-time alerts at any time.
In Shuttle, go to Inventory > Stock Rules.
On the Global Rules tab, click Edit next to the rule you want to change.
Under Timing, choose Real-time, alert immediately or Fixed-time, alert once a day.
Click Save.
When you add a quick rule, you choose its timing under When to alert: Real-time or Fixed-time. A quick rule's timing can't be changed after the rule is saved. To change it, delete the rule on the Quick Rules tab and add it again with the timing you want.
