Hey Alicia Bruckman,
This doc gives the list: Marketo Activities Data Retention Policy
- Change score
- Change data value – except changes to the Lead Owner and the Company Name fields
- Visit webpage
- Click link on webpage
- Sync lead to Salesforce.com
The doc is very poorly named, as it is describing both the complete archiving of anonymous leads (now no longer an issue, as Marketo no longer creates anonymous lead records) as well as the archiving of certain activity types only for known leads after 90 days.
The wording of the doc makes this rather confusing unfortunately.
