When sending email messages in BBIS, you might notice that email messages are still sent to constituents who have the "Do not send email to this address" flag on their primary email address.
We are currently evaluating this issue for a fix in a future service pack.
Steps to Duplicate
1) Create a new constituent and add an email address. Mark the checkbox for "Do not send email to this address". 2) Create a dynamic constituent selection containing that constituent. 3) In BBIS, create a new constituent list using the selection created in step 2. 4) Send an email message using that constituent list and notice that it is received.
