problem sending


I have a problem sending yesterday
I launched the campaign mailing of different smtp servers but until today the shipment is set to 0%
Another thing is when a client sent me a ticket via support ticket, I do not receive a notification by mail and when someone been registered with the mailwizz it does not receive the activation email
this is a new problem for two days
Then something isn't working properly, mailwizz can't send those emails.
Look into backend -> misc -> transactional emails, and see what's the status of those emails. If it's unsent then your cron job for transactional emails doesn't run.
Also look into Backend -> Misc -> Application log for additional info, you might find that the app can't find a valid delivery server to make the delivery.
