Good morning,  
  
I apologize for my English.  
  
I’ve created a test campaign using a list with only one contact. I’ve created all the flush, but the mail does not start. I use SMTP as a system to send mail.  
  
SMTP connection and mail sending tests, it works, but in the campaign does not work.  
  
Can you help me?  
  
Thank you

hi @valvasori : You have configured the Cron-Jobs according to this: [https://mautic.org/docs/en/setup/cron\_jobs.html](https://mautic.org/docs/en/setup/cron_jobs.html) ?
