Since femanager is created with Extbase, it is easily extendable and I created a small TYPO3 extension named femanager_dmail_subscribe, that automatically adds "Newsletter subscription", "Newsletter category" and "HTML newsletter" direct mail fields to femanager, so editors can select the direct mail fields a frontend user should be able to edit.

In order to display direct mail categories in the frontend, it is required to add the sysfolder with the direct mail categories to the femanager record storage page.

I uploaded 2 versions of the extension to TER. Version 1.0.0 is compatible with TYPO3 6.2 and femanager 1.5.2 and version 2.0.0 is compatible with TYPO3 7.6 and femanager 2.x
