To understand what constitutes as valid email addresses, we can Create a Query to find this number. In query builder, create the following clauses:

Field Type: Email
Field: Accept Email
Clause: equals true
AND
Field Type: Email
Field: Email Status
Clause: not equal to Bad (Hard Bounce)
AND
Field Type: Email
Field: Email
Clause: is not blank
AND
Field Type: System
Field: Active Status
Clause: not equal to Removed
AND
(Optionally add this filter if you use the deceased field)
Field Type: Biographical Information
Field: Deceased
Clause: equals false

If you only want to see valid email addresses in a specific group, then you'll want to Add a Group Clause, but if you want to see all valid emails in your database, then you can leave this part out.

So after considering the logic used in the query, here is what constitutes as "valid" email addresses:
  1. Their Accept Email must equal true.
  2. Email Status cannot be equal to Bad (Hard Bounce).
  3. Their email cannot be blank.
  4. System Active Status cannot be equal to Removed.
  5. The constituent is not deceased.
