Like they have said, they are wanting to work with you to get your open rates through the roof right from the get go. I know Aweber will warn and then ban you if you go under 10%. Ideally they want to be working with you to get your open rates beyond 20% and more. But they are marketers - they understand that sometimes things are outside of your control. They aim for you to achieve 5% open rates at least, but also factor in spam rate & bounce rate. And as long as you're well intentioned and willing to work with our team, they are happy to assist you out to achieve the sort of open rates you desire.
