Open stats are updated every 15-30 minutes, but sometimes it can take a little longer to update these stats when MailChimp is exceptionally busy.
Clicks get logged right away and do not go through the same process as opens. So you may see some clicks right away, but very few opens. This process can take about 10 minutes for smaller lists, or 30-60 minutes for very large lists.
Abuse complaint stats are updated in real-time. Simply refresh the stats page to see the most up to date data.
Bounces are checked every minute, but can take longer to update sometimes when the email sending service is backlogged.
When you activate SocialPro, it can take anywhere from 24 hours to a week to back-fill information for existing subscribers on your list. After that, SocialPro is updated approximately every 2 hours to retrieve information for new subscribers and to update the statistics for your list. The size of your list and the number of other requests in the queue can affect how long it takes to get this data.
