That is not advised. Everything you want to say for that day of the challenge should be covered within the video itself. The written part of the email should just be short and simple and the idea is to just get them to click the video like we have it formatted in the template for the emails.
For the funnel build outs as a general rule, the information being submitted to our team should be a 100% match to the templates provided in terms of formatting, length etc.
Once it's built out for you, you are free to experiment and adjust HOWEVER as Dr Shaunna has mentioned and taught us before, that usually will make things work LESS instead of better so we highly recommend not changing anything.
You are paying for access to our proven processes/systems and changing it would no longer make it a proven process because we haven't experimented or tried that yet (like adding in extra resources onto an email, etc). Testing new ideas always has a cost associated with that test. A saying Ryan (our main Marketing / Tech Guru) likes to remember is "replicate before you iterate". Meaning replicate the process exactly until you get the same results or better as the people who are using the same systems (ie. reach multiple six-figures) and then and only then after accomplishing that should you try to iterate on the model by making changes or trying something new.
