Quick Answer: Looker Studio schedules most often fail because the report contains an error, the email quota is used up, or the person who last saved the schedule lost access. Check those three first.
A client asks where their report is. You open Looker Studio and the schedule is right there, set for Monday morning.
Nothing was sent, and nothing told you.
This guide lists the reasons Google's own documentation gives for scheduled deliveries not arriving, with the fix for each. If you run client reporting on Looker Studio, bookmark it.
1. The report contains an error
If the report has an error when it is downloaded, Looker Studio does not send it.
Fix: Download the report manually as a PDF before you rely on the schedule. If the download fails or shows an error, fix that first.
2. A chart timed out ("System Error")
Large reports can time out while being exported, which shows up as a "System Error" on individual charts.
Fix: Google suggests splitting the report into smaller reports, and staggering delivery times by at least 30 minutes so exports do not compete.
3. You hit the email quota
Scheduled emails have daily and monthly limits:
- Individual Google account: 200 per day and 800 per month
- Google Workspace account: 500 per day and 3,000 per month
- Looker Studio Pro: no limit
Once you pass the quota, further emails from that account are not sent. Google also notes that you cannot check how much of your quota you have used.
Fix: Spread large sends across days, use a Workspace account, or move to Pro. Count your sends: one schedule with 50 recipients is 50 emails.
4. The person who saved the schedule lost access
Schedules run with the credentials of the user who last saved them. If that person becomes inactive or loses access to the data, the schedule fails.
Fix: An active editor can open the schedule, edit it and save, or create a new schedule. For agencies, the lasting fix is to make sure schedules are saved by an account that will not be removed when staff leave.
5. A recipient is restricted (Pro)
On Pro, if an administrator restricts any recipient, the schedule does not send until that recipient is removed. The last editor gets a warning email.
Fix: Remove the restricted address from the recipient list, or ask your administrator to lift the restriction.
6. A licensing change has not propagated (Pro)
After a Pro subscription or license change, it can take up to 24 hours for the change to take effect.
Fix: Wait, then check again.
7. VPC Service Controls change what is delivered
If your data is protected with IP-based access levels, emails may contain only a link, without the PDF or inline images.
Fix: Google recommends using service account credentials.
Limits to know before you build more schedules
These are not failures, but they catch agencies out:
- Without Pro, each report can have one schedule, and the fastest it can run is once a day
- Pro allows up to 200 schedules per report, as often as hourly
- An email schedule supports up to 50 recipients, and the person who creates it must be on the list
- Reports in the "Owned by me" folder are subject to quotas, and they do not get "Send now" or a custom subject and message
Why this is risky for client reporting
Every cause above has one thing in common: the failure is quiet. Nobody is alerted, and you find out when a client asks.
That is fine for an internal dashboard. It is a problem when the report is something a client pays you for.
What LedgeSpace does differently
LedgeSpace is built around client delivery:
- Schedules are stored per client in your agency account, not tied to one person's credentials
- If a connected platform has not synced when a report is due, the report is held and you get an email alert and a dashboard notification naming the affected integration
- If you do nothing, LedgeSpace sends the report after 6 hours with the data available. If an integration is fully broken (expired or revoked), the report stays held and retries daily until you reconnect
- Reports go out as a PDF plus a secure web link, from your own SMTP, and Client Pulse shows which clients opened them
There is a 14-day free trial with no credit card, so you can run one client through it alongside your Looker Studio setup. For a full side-by-side, see LedgeSpace vs Looker Studio.
