Hello, I just test your newsletter plugin for wordpress. Unfortunately I can not send mails. The mails are marked as shipped but none arrives at the recipient. Can it possibly be because I have not set up a page for unsubscribe or double opt in which the mails are not sent? Does such a page necessarily have to be created in advance?
A testmail over the general settings can however be sent, but takes extremely long until this arrives about 25 minutes.
