Your messages can take whatever format you are most comfortable with - a brief note, a postcard, a thoughtful essay - as long as it shows your enthusiasm and passion and clearly reiterates our desire to see the same cast and creative team on the show.
Your messages can be sent directly to Hulu and Mr. Craig Erwich, but in order to make as much of an impact as possible, as a unified fandom, we want to schedule our emails and letters to arrive as closely together as possible. That means that for this particular event, we will use Wednesday as our email days (send out your emails on Wednesday) and Friday as our snail mail days (drop your letters off at the post office on Friday).
If you are writing from outside the United States and Canada, you may want to send your physical letters earlier than indicated above, depending on your home country, in order to adjust for the delay of international mail service.
Please have a look at our dedicated Write to Hulu page for information on where to send your letters, printable postcard files you can use for your own snail mail efforts, as well as some helpful pointers for best to get our message across.
