Extension Issue of BulkEmailChecker.com


I brought Bulk email checker extension from codecanyon and 10,000 verify package with v3 API setting.
The issue is when I import list, the mailwizz stuck and none of emails has imported.

is there an standard setting to use this extension? Thanks
@hezinai - what is your settings from Backend > Settings > Import/Export?
Note that when the BulkMailChecker extension is enabled, it will check all emails, even the ones that you import and this can cause a timeout issue if their api is responding too slow. In this case, you should import as few subscribers at once if possible, so the Import at once setting should be somewhere at 50 instead of the value you have now.
