After setting up a test email, there seems to be some issues.
After Navigating to:
SendPress > Emails
I'm able to preview the email, as I created it, when I press the "View" button.
From the same navigation location (SendPress > Emails), I'm able to edit the email, when I press the "Edit" button.
From the same navigation location (SendPress > Emails), if I press the "Send" button, It displays the 404 error page of my theme as a preview.
From the SendPress > Emails > Send navigation location, when I press the "Send" button, It displays the 404 error page of my theme as a preview.
If I click the "Confirm Send" button and send the email anyway, the email comes through, as it shows up after pressing the "View" button (as it should).
I'm not sure what is supposed to show up, in the "Send" screens, but I'm sure it isn't a preview of the 404 error page of my theme.
All delivered emails are being delivered to the spam folders of my test email accounts.
The tracking for "Opens" and "Clicks" seams to be working, at least partially.
I sent the same test message to a test email account twice, under two separate send attempts. I opened the email and clicked the link, which shows up in:
SendPress > Reports
under both the "Opens" and "Clicks" columns.
However, every single time I refresh the view of the email, another "Open" is tracked. If I click on the link again, another "Click" is tracked. While it may be of interest, to know how many times a single person opened an email and clicked on the link, it is far more useful to know how many of each email address, in the specified list, opened the email and clicked the link.
For this plugin to be viable, people will want to be able to track the "Opens" and "Clicks" from each subscribed email address, independently. In other words, after an email is sent, I want to be able to go to:
SendPress > Reports
...Click on the email sent, and see a list of every single subscriber, that email was sent to, along with the "Opens" and "Clicks" of each subscriber. The success rate of an email campaign is how many of the entire list, opened the email (once) and clicked the included link (once).
The only way to do this is to add some sort of hash-tag to the links, in the email, which identifies each subscribers email address, separately.
