# Activation key?

 * Hello!
 * And thank you for a great plugin. 🙂
 * With MailPoet3, there seems to be no activation key. It is not sending out newsletters–
   or at least it seems that way. I did read here that previous newsletters not 
   appearing could be a cache issue.
 * Is the activation key needed, and if it is, where can it be located?
 * Best wishes,
 * Mika Perkiomaki

 * Hello,
 * Automated newsletters are not being sent. Test e-mail works fine.
 * Is the activation key the cause for this or is there another reason for the newsletters
   not being sent?
 * Best wishes,
 * Mika

 * Hi there Mika,
 * Which sending method are you using? The MailPoet sending plan or PHPMail based
   normal sending?
 * If you’re using the MailPoet free sending plan, you’ll need to make sure you’ve
   activated your API key within the plugin for the sending to work.
 * Thanks!
