I like that we can easily send physical letters to customers, so they don't have any issues receiving them in person or having it delivered somewhere else than their home/office (which is very common these days). The only thing i dislike about this service are those pesky "we missed you" emails from time to time where some addresses, were not entered properly by us but still got sent out anyway... Also sometimes there's no way for me as an admin user of my account within PHA itself. Especially when creating new users via API integration which requires manual approval after creation. I like how simple it is to sign up for an account, as well that there's not any setup fee or anything of its kind. It'd be great if you could add more states in addition too this being able do show multiple addresses at once instead one by it.
