When working with clients I often see records from imported lists where the email address field is empty. The email address is often mistakenly imported into the incorrect column/field. Using a list import template and having a QA process will help prevent the issue from happening. But if it does happen, often weeks can go by before anyone notices and corrects the error thus losing the ability to follow-up and nurture the records in a timely manner.
Here are smart lists you can setup and subscribe to be alerted of an issue.
Missing Email Address - List Import (Created in past 24 hours): Set the subscription to this list
Missing Email Address - List Import (Created in past week): Use this list to investigate the issue
• Based on Original Source Type is List import
In this example, I created the smart list in my master data management program.
