indicate that they would like to recieve the newsletter (see Azine\EmailBundle\Entity\RecipientInterface.getNewsletter).

Depending on you Swiftmailer-Configuration the email will be send directly or will be written to the spool.

If you configured Swiftmailer to spool email, then you need to run the <info>swiftmailer:spool:send</info>
command to actually send the emails from the spool.
