sending newsletters with Mandrill

I would like to use Mandrill with newsletter.
I dont need to use crown jobs if i use Mandrill?
That post was very nice https://premium.wpmudev.org/blog/how-to-ease-the-load-of-sending-email-from-wordpress/
But it would be nice to explain that little more about how to use it with newsletter.
Seems very interest. (i have a long email list)
