I have an Email Performance Report that is sent weekly to my boss. It covers all emails sent since we started using Marketo - we want to track the average open rates, etc. The report previews 30 rows. However, it previews the FIRST 30 emails sent. Is there a way for it to preview the LAST 30 emails sent? That way we could see the average, and the results from the most recent emails.
If you have RCE, you may be able to force the report to do this by using the Sent Date filter.
I would recommend that you consider changing the report to Last 7 Days or Last 30 days of emails because it will be less taxing on the system, then your manage could go in to check the Rolling Avg from other timeframe reports.
