About those "It looks like you haven’t opened an email from us in quite a while. We
still think you’re pretty, but we don’t want to keep poking you if
you’re not into it."-type emails... They look needy, and - to be honest - it's my choice whether or not I allow remote content (trans: "whether I want my reading tracked") when I open my email. Please don't do that. It's not best practice, and it's an active off-put. If people want to unsub, they will. Thanks for listening.
