Hello, I got a problem that some people are not receiving the discount mail (first mail in welcome serie).
They are not from Germany/DE I checked this. After signing up they should immediately receive this email.
We use single optin.
As you can see events below, they are subscribed but no mail is being send. How can I make sure everything is getting this email, because now some people are contacting support about this and its not good for conversions offcourse.
