The official support channel is this support forum, which is public. Only premium users can open a new topic. For free plugins, we also support via WordPress.org support forum.
Besides, there is a Facebook group, which is for community discussion, not for support.
We rarely support via email. Email is mostly used for sending private info. Please use this support forum first before sending us emails.
We only support our plugins, not general WordPress issues (like custom post types, custom taxonomies, etc.). Our support includes plugin installation, configuration, update and use.
