- A reserved entry group is close to using up its held-back capacity.
- The remaining inventory on an add-on drops below the point where you’d want to restock or promote it.
- Your Meta Ads return on ad spend (ROAS), the revenue you make for every dollar spent on ads, falls below a level you’re no longer happy with.
Time-based alerts
Nova emails you at a time you choose, and can re-run an analysis so the
result is fresh when it lands.
Metric-based alerts
Nova checks a number on a regular schedule and only emails you when it meets
the condition you set.
Setting a time-based alert
Ask Nova to remind you at a specific time or after a delay, in plain language:- “Remind me tomorrow at 9am to review my registration numbers.”
- “Check back on this in two hours.”
- “Re-run this analysis in three days and email me the result.”
Setting a metric-based alert
Ask Nova to watch a number and tell you when it meets a condition:- “Email me when the reserved entries for my club group are 90% claimed.”
- “Alert me when the remaining inventory on my shuttle add-on drops below 20.”
- “Let me know when my Meta Ads ROAS falls under 3.”
- The condition in plain language, for example
Email me when registrations per day < 50. - The schedule — when the first check will happen (relative time plus a formatted date) and how often it repeats after that.
Watching a value versus watching a change
A metric-based alert can watch two different things:- A fixed value. Nova compares the number to your threshold on every check and emails you on the first check that meets your condition. “Email me when registrations drop below 50” works this way. Nova emails you the first time a check finds the number below 50, even if it was already below 50 when you set the alert up.
- A change. Nova compares the number to what it was at the previous check and emails you when the change is large enough. “Tell me if registrations fall by more than 100 in a day” works this way.
How often Nova checks
Nova checks a metric-based alert at most once a day. This means the number you’re watching has to be measured over a window of at least one day. If you ask for something faster, such as “every hour” or “in real time”, Nova will tell you it can only check once a day and ask you to widen the window. When you set the alert, you choose how often the check repeats (for example every day, or every 3 days) and Nova keeps checking on that schedule until the alert ends.What the email contains
You only get an email from a metric-based alert when the condition is actually met. Until then, Nova checks quietly in the background and says nothing. When the condition is met, the email:- Has the subject line From Nova – Threshold alert: followed by the alert’s title.
- Tells you the current value and how it compares to your threshold. For a change alert, it shows the amount it moved (from the previous value to the current one).
- Includes a link back to Nova so you can explore the full picture.
Viewing and cancelling your alerts
Ask Nova to show you what’s currently active:- “What alerts do I have set up?”
- “List my reminders.”
- “Cancel my alert about registrations dropping below 50.”
- “Stop the reminder you set for tomorrow morning.”
Limits
A few limits keep alerts manageable:- You can have up to 52 active reminders at once.
- You can have up to 10 active metric-based alerts per event organizer.
- An alert can run for at most one year. Nova won’t set up a schedule that would keep checking beyond that.
When a metric-based alert stops on its own
What happens: Occasionally a metric-based alert stops before you cancel it, and Nova emails you to explain why. Why: There are two reasons this happens.- The number tracks financial data your account can no longer see. If your access to financial figures is removed after you set the alert, Nova can’t keep checking it, so the alert is cancelled and Nova lets you know.
- The number can no longer be worked out. If the underlying figure can’t be calculated any more, Nova cancels the alert rather than sending you broken results, and emails you to say so.
