In an effort to improve your email deliverability, you are building out a checklist that every marketer should reference before sending an email. All of these things should be added to your checklist EXCEPT:
A) Do you have explicit permission from this contact to email them?
B) Do you know what expectations this contact had when giving us their email address?
C) Do you know how this contact ranks on the deliverability/engagement matrix?
D) Do you know the original source of this contact?
