How can I send a book to more than one Kindle email address?

So, you want to read an ARC on multiple devices, huh? We get it. We're the same way. Luckily, this is easy on BookSirens.

1. First, find the Kindle email addresses you'd like to send the book to.
2. Go to your downloads page and click Download Again. 
3. Select the Mobi or ePub format and the Send to Kindle delivery method. Enter the first Kindle email address you found in step 1 above.
4. Click Get Book.
5. Repeat steps 3 and 4, entering the next Kindle email address you'd like to send the book to.

If a few minutes have gone by and the book is not appearing, make sure your devices are connected to the Internet and that you've added kindle@booksirens.com to your list of approved emails. More detailed instructions here.
