If you use automations in Mailchimp you may notice that the options for managing the campaign results associated with these has changed from the latest version(4.12)
Previously we had the option to bring in automation emails from a certain date (see below). Unfortunately Mailchimp do not actually provide us a with a date to allow us to filter these results so we have now removed the date field.
In version 4.12 You will see the below screen instead.
We have raised this with Mailchimp but they are not planning to change what is available for automations so this is unlikely to be updated.
