When sending an email it says how many recipients it will be going to and then it says underneath how many recipients won’t be included in the email send; however, it does not offer any information other than that. I would suggest providing a link to those contacts with reasons why they won’t be included so they can be fixed.
Yes please I have been requesting this for over 2 years. It is super frustrating, it knows how many won’t be sent but no explanation as to why. Why can’t it just create a link to the number that won’t be sent and open up a list of them so we can see who they are?
