We'll add this to our list, but this is the first time I'm aware of that someone has asked about it. And our focus is on adding features that have the widest appeal possible, for all customers across all industries.
That said, SmarterMail is completely API-driven and there are APIs for virtually every feature within SmarterMail. So, if you wanted, it should be possible to build (or have built) a "skill" for Alexa, using SmarterMail's API and the APIs available from Amazon.
