Get objects from a many to many field

I have an m2m field called "admins" inside a model and I need to obtain from a view all the selected entries in that field, which are user IDs. Then with the user IDs obtain the emails for every user. Is it possible?

The exact thing I want to do is to send a mass email to all the admins of a space inside this platform.

Spaces model:

class Space(models.Model):

    """     
    Spaces model. This model stores a "space" or "place" also known as a
    participative process in reality. Every place has a minimum set of
    settings for customization.

    There are three main permission roles in every space: administrator
    (admins), moderators (mods) and regular users (users).
    """
    name = models.CharField(_('Name'), max_length=250, unique=True,
        help_text=_('Max: 250 characters'))
    url = models.CharField(_('URL'), max_length=100, unique=True,
        validators=[RegexValidator(regex='^[a-z0-9_]+$',
        message='Invalid characters in the space URL.')],
        help_text=_('Valid characters are lowercase, digits and \
    admins = models.ManyToManyField(User, related_name="space_admins", verbose_name=_('Administrators'), help_text=_('Please select the \
        users that will be administrators of this space'), blank=True,
        null=True)
    mods = models.ManyToManyField(User, related_name="space_mods",
        verbose_name=_('Moderators'), help_text=_('Please select the users \
        that will be moderators of this space.'), blank=True, null=True)
    users = models.ManyToManyField(User, related_name="space_users", verbose_name=_('Users'), help_text=_('Please select the users that \
        can participate on this space'), blank=True, null=True)
