Far relationships in Laravel

My database structure looks like this:

User
    id - integer

user_user_group
    user_id - integer
    user_group_id - integer

meeting_user_group
    user_group_id - integer
    meeting_id - integer

meeting_mails
    meeting_id - integer
    sent - boolean
    date - date

meetings
    id - integer

I have a user from whom I need to get the meeting_mails where sent == false and date == today. Is there a smart way to do this in Laravel, or do I have to write an ugly SQL query by hand?
For performance reasons, I would like to make as little as possible with collections or arrays and let the database do as much as possible.

I'm using Laravel version 5.8
