Opt users out of certain email types
It would be extremely helpful to have the option to only subscribe contacts to a certain email type when they fill out a form, instead of automatically opting them into ALL email types automatically. At least have the option to opt contacts out of certain other email types.
The reason is, if you wanted contacts to opt into your blog subscription emails ONLY and not any other email types, then that should be the only email type they should be subscribed to. I don't want contacts to get any other email types (if, let's say that I send out a marketing email that they weren't subscribed to).
