It does include email.
For me, changing the mx records to point to my self-hosted exchange server rather than google is not a big deal - a few seconds on OVH's control panel plus maybe a minute or so to set up the accounts on Exchange, then copy the old emails across to the new mailbox and change the account settings in all the email clients.
I mostly use it for YouTube, so migrating all that across to a new gmail account is doable but much more of a pain.
