To() method that takes a collection of addresses (suggestion)

I wanted to send a new email to some addresses stored in a IEnumerable. To make this job a bit simpler I created an extension method to provide an additional method: To(IEnumerable string emailAddress). I could make a pull request to extend the IFluentEmail interface with methods that take an array of string and IEnumerable of strings. What do you think about such a solution?
