I created some custom fields for my Wordpress users (with Ultimate Member plugin). These fields are thus located in _usermeta table in the database.
I would like to synchronize my "all wordpress users" Acymailing list, including these fields, to be able to make some filtering when preparing a new campaign.
I created the equivalent custom fields in Acymailing, ... but I don't see any way to synchronize my Wordpress custom fields with these one.
Anyone knowing how to do that?
Thanks for your help!
