We use the phones/emails INACTIVE checkbox to exclude certain phones/emails from mass communications.  Fundraisers who need phones/emails for individual communication must therefore check SHOW INACTIVE PHONES AND EMAILS in database view (or INCLUDE INACTIVE in webview contact information tile) each time they open a constituent record.  It is challenging to get them to remember to do this, leaving them to conclude erroneously that no contact information is available.

Option to leave SHOW INACTIVE always on could be either side-wide, or per user, via user options.
