I have an observations which look a bit odd, that there are open and clicks records in tracking logs for the emails with error status (i.e. Email Unknown Error, Email Soft Bounce and Email Hard Bounce ). All the other three status reflects that the email is not yet delivered. If the email is not delivered then how come we are receiving the tracking for those records?
Does anyone have any explanation on this?
Also, wanted to know what does "Email Unknown Error" status actually meant?
Email Unknown Error - It is a hard bounce, which occurs when email address is incorrect.
Regarding Tracking Log data:
It’s likely asynchronous feedback loop ( for ex: Customer marked the email as spam ) that changed the status of broadlog to failed from sent. Please check if the records you’re seeing are also in nms:Address table to confirm this.
