Hi,
Use a copy of your production database for testing so that your real data and emails are not affected.
Activate Developer Mode by going to Settings and clicking “Activate the developer mode” to access technical features.
Go to Settings > Technical > Automation > Scheduled Actions and use the “Run Manually” button to test your automation.
Add log messages or print statements in your server actions or custom code to confirm that automation is running correctly.
Reduce the interval time for scheduled actions to run more frequently during testing (e.g., every minute).
Once everything works, you can safely move your automation setup to the live production system and monitor the results.
Hope it helps.
You should be able to run the Server Actions manually.
