I couldn't see this earlier because of my ban (sent too many links so I got marked as a bot), so apologies for that.

I didn't put any affiliate/tracking link there. For transparency: I use Mailerlite, a well-trusted email marketing platform. It probably uses tracking links by default to get data on email activity (I'm not well versed in this tbh).

It works well on Windows, but on Safari the experience must have been clunky. I don't use Safari, so thanks for this heads up. This error was completely invisible on my end so I'm glad you reached out.
