… I’ve just realized (unless I’m mistaken) they can’t be used in the obvious places you’d think and want to use them.
For example, I have fields for country and age bracket but I can’t use these custom fields to:
a) Target an email (i.e. to subscribers in a particular country or age bracket).
b) Filter the subscriber list (i.e. to quickly see how many subscribers in a particular country or age bracket).
c) Import email addresses or update the mailing list with custom field values (or even preferences for that matter) so then they can also be used for (a) and (b).
Not being able to use custom fields for these kinds of things seems like a major limitation on their usefulness or value.
And of course one would like to perform wild card (simple and regular expressions) with boolean expressions (and, or, not, brackets, etc.) for (a) and (b).
Are there any plans to allow the above and, if so, any estimated time when that might happen?
