The Preference Grid is a quick and easy visual guide to people’s contact preferences (Phone, whatsapp or email), what people in the agency are willing to do (in white), would like to be checked for (in orange) and are unwilling to do under any circumstances (in red). It is an Excel Spreadsheet that can be found on the ACT Links page. It is an ever-evolving document that should support TagMin and your own knowledge. It matches the Yes-To filters in TagMin.
Be sure to keep your own preferences up to date.
