In your opinion, what's a successful layout for a high-performing email?

I’m saying this as person that gets a ridiculous amount of marketing email. you have 1 relevant email title, and 2 sentences to convince me to not delete the email lol. - I’ll even admit that sometimes when I get emails titled “Act now and save” - i take the advice, instantly delete and save 100% by not wasting my time reading the rest, and if someone is too persistent with those psycho hack type messages, I’ll ask to unsubscribe or block when necessary. as the meme goes, “Ain’t nobody got time for that”
