I have a custom field "country" of type "text", when I use a filter on this field, the list of countries I get is not ordered:
It is possible to get the list alphabetically ordered?

Please raise a support ticket (https://www.acymailing.com/support/) for this, it's something we can't solve on the forum.
That said, why don't you use a dropdown field insted? That way you can add the countries in alphabetical order, it's more user frendly and it will prevent users from making typos that make your filtering more difficult.
