Once you have decided on your prospects for collaborations, you are going to email or connect with them to ask if they would love to share your offer!

I recommend before emailing them that you start loving all over them on Social NOW. Shout them out, share their products, comment on their posts. So they get used to seeing you and won't mind sharing your challenge out on social or in their newsletter. 

We will schedule out sending out those emails/messages a few weeks in advance so they have time to schedule it! I love how Reina from Reina & Co. calls people launch cheerleaders :)
