In the program, Paul talks about a 1:1 ratio with your emails. Meaning for every promotional email you send, you should send a value email.
Promotional Email: The purpose of this email is to sell something.
Value Email: The purpose of this email is to educate your prospects and offer them something for free.
Therefore, we would advise sending a mixture of value/promotional emails. Furthermore, you may wish to combine your emails so they contain value and promotional.
For example, sending a top 5 tips email with an upsell at the end of the email. However, the key is to provide value then promote.
