5 stars thus fars

I like this plugin a lot! Have used it so far for one email to a couple thousand subscribers which is a good test, and it looks rock solid.

The downsides: the UX is a little janky (for example, Subscribers > Unsubscription and Subscription > Unsubscription both lead to the same fairly useless page which lets you customize the unsubscribe message. Subscribers > Statistics > By Time shows two confusing line graphs… apparently the “by day” is subscribers added each day non-cumulatively, and “by month” is the same info cumulatively? Seems like there could be better statistics.) We got 20 unsubscriptions and ALL 20 show the EXACT same time and date for when they unsubscribed… is that a bug or did Newsletter’s unsub link get auto-clicked by the mail client? And the documentation isn’t always great; I used trial-and-error to figure out which variable name to use for subscriber firstname because the docs were no help. Lastly, the mail tester at aboutmy.email says that the Newsletter list-unsubscribe header is outdated. “List-Unsubscribe header has been MIME encoded. This may work at some mailbox providers but is not valid.”

That said, these are minor gripes compared to the overall positive: this does the job well, it supports unsubscribe headers and list mail merge, and it creates a legit unsubscribe page on my WordPress site for full Google/Yahoo compliance.
