I have tried team mail and SFI chat, but the best and unfortunately the most under utilized is the Stream Post.
every single person on your team, including your downlines and A2A friends.
So it serves your whole team.
what is more, it allows anyone of your team member to reply to your message instantly.
the downside of it is that it is public.
but our business is public, every one deserves to earn that information or experience.
so start using Stream Post today
