Both lists are important and necessesary. INVALID EMAILS and INVALID DOMAINS
For the EMAIL denial list, at the time you verify the validity of each email being suscribed, we must compare this email as if it is LISTED OR NOT in the NOT ALLOWED LIST, to be acceppted or not. Otherwise, display a non-valid email message.
Marking an email as UNSUBSCRIBED or BOUNCED will not do a REAL DENIAL, as we will have to mark it again and again and again everytime the user changes his subscription status.
> Unsubscribed address cannot change the subscription details.
That’s great to know, thanks.
However, that does not solve the problem as the FCC publishes a list of non-allowed emails as well. And you too, you may want to work in the safe side of not sending any emails to some specific email addresses, wether that is in some cases or in all cases. The list of invalid emails comes very handy in this case.
In the other hand, the list of INVALID DOMAINS, it should accept the list as published by thye FCC, without requiring any changes by the user.
Also, the “EXPORT” feature should allow for exporting ALL, SUBSCRIBED, UNSUBSCRIBED, BANNED, or anything the user selects, it should not export all emails but only at user’s choice and convenience only.
