To certain extent, if you are sharing part of your daily life experience with your list of subscribers, they will get to know you more and start building their trust on you. In the mean time, they learn about something that work for you and might start sending enquiry to you about the product that you promoted.
It is important to treat your list of subscribers as your buddy. Don't use hard selling word in your follow up email to them as this will just make you appear like a scam. Instead, use softer tone in your mail and share out the benefit you gained from certain product that you are promoted. Always hand the decision right over to your subscriber to let them decided whether they want to purchase your product or not. This will look more appealing to your subscriber
