Just thinking out loud a bit more…
A lot of our announcements involve a link to things. Here’s an actual example:
I have two links there at the bottom, but I could (and often do) just link to the Event page on our site (the “more info”) link.

I haven’t tried the plugin yet, but it looks intriguing, especially if it sends out messages that emphasize the link.
