you're not what you were
I like both formats! But short form content is a lot quicker to read/digest and if your subscribers get used to it, you may find you’ve got a higher amount of read emails.
I do think you should promote stuff still. But a smaller email gives readers focus (oh, he wants me to do x thing), rather than giving us too many choices.
That’s a UX law, by the way - but I can’t remember which and I’m sure you already know that!
