[RESOURCE PINNED IN COMMENTS] One of the best warm email marketers I know got on a call and pitched me a $10,000 install. The promise: every marketing email you send lands in the primary inbox, never the Promotions tab. I asked how. Special warmup? Copy trick? Nothing useful came back. So I opened one of his emails in Gmail, hit Show original, and read the code Gmail reads instead of the text you read. There's a block of text in there you never see. About 300 words, boring on purpose, someone thinking out loud about the same topic as the email. Hidden behind CSS so the reader never sees it and Gmail reads all of it. That's what moves a promo out of the Promotions tab. To Google your email reads like a long personal note that happens to mention a sale. I'm calling it ghost ink. The biggest names in marketing are already using it and nobody talks about it. Fair warning, it only works if the boring stuff is right first. Clean domain, correct records, a good IP, decent copy. This takes you from Promotions to Primary. It will not pull you out of spam. Full breakdown in the new video, including the four things that break it (one of them is copying my paragraph). Real examples of my ghost ink are linked in the description, free. Watch it here Do you have a warm list you are going to use this on?
