Export List’s Opted Out Users via API and Bug Fix
On January 19th, 2017 we released a bug fix for exporting a List’s opted out users. Smart Lists with multiple criteria were only counting user’s who had opted out of a template as well as mass or all sends. This would cause the list to significantly undercount the opted out users.
On January 24th, 2017 and addendum will be released to stop including users who opted out of a template then opted back in.
In addition to the fix, we enabled this option via the API. You can now run an “export_optout” Job via the API to pull these list types. This was previously only available in my.sailthru.
