Currently there are six output fields in emails sent to users. Since the six fields don't really require explaination, I will just skip that and detail the problems with just using the six fields and why a seventh field is more important. For those that want to see the current mock template see: A template version . Filtering emails currently can be done, using forum titles, the GameMaster (or friends) name or the fact its Roll20 or your name with Roll20. To filter in a more effecent, preplanned manner, a seventh way to filter emails is required, this information can in theory be pulled from the Forum Name. Because the View Post links are not a direct link, it cannot be tested in a filter rule (at least not easily if its reversable). Titles of forum posts are good when you follow a Suggestion & Ideas post, you know the title of most of the suggestions you follow. A gamemaster is a good way to get some of the better part of emails to your filtered location but doesn't help if a player asks a question and the GM just replies. Sometimes thou, you are either helpful, a gm, or otherwise need better handling of emails. The Forum Location can help filter emails down to per campaign, less important but still important Suggestion & Ideas, or interests you may have such as a new post has been made in API which has a custom filter, and a Dev has responded which gets a even more bling filter added to it. The general and more practical use for me personally, is to allow me to filter emails to each campaign I'm in or run, and have a generic non-filtered roll20 folder to group everything in. A mock template and an actual example below.
