The write up on the official adespresso page is pretty vague, so I sent them some questions and this is what they replied:
- Auto optimization triggers once a day normally during nights. Your campaigns will be self optimizing once they have enough data to check and see which are the top performing elements within the campaign.
- Usually we suggest to set up at least $5 for each ad set you are running.

- Automatic Optimization includes some rules that give a frequency cap and examines all the ads within your campaign by CPA- pausing the under-performing ads and allocating budget to the best ads within the campaign.
We cannot share the specific rules.
Bummer, so not specifics on how/what, but at least we learned that it runs once a day during night time.
