I just changed my daily email newsletter from Mailchimp towards The Newsletter plugin. But I have a problem. The delivery is not working. I'm not getting my own newsletter. Whats happening? How is this possible? I checked all folders (including the SPAM folder).
Delivery depends on your hosting. Run a test from the status panel, is nothing is actually reaching your mailbox, ask the provider for problems or limits. Ask them an SMTP as a possible alternative.
