My #1 rule on follow up is that you must be peristaltic, but not annoying. Be creative with his you are reaching out to them. I've been featured in a few articles on Inc. and Creator Magazine for how unique my follow up is.

If you want some help strategizing for 5-10 minutes how you should follow up, shoot me a message and I'll help you out.

I hate the feeling of being anxious on call follow up, but if you go about it the correct way and do it confidently, they will eventually respond.
