Created and sent a small newsletter this evening. Later, I went to Statistics | Links Details and also to User Click Details and found about half the links listed there don't even exist in the newsletter I sent. All are links I had used at one time in previous newsletters with one link going all the way back to 2018.
So I searched the newsletter HTML code for "href" to view every link in my newsletter and I found none of the incorrectly listed links are in tonight's newsletter.
So why are they showing up in the Links Details?
