AI Email Marketing: Prompts That Actually Convert (Not Generic Slop)
Most AI-generated marketing emails are terrible. They’re generic, overly enthusiastic, and read like a robot trying too hard. But with the right approach, AI can help you write emails that actually perform.
My process:
1. Never start with “write me a marketing email.” Instead, provide context: the product, target audience persona, their main pain point, and the specific action you want them to take.
2. Feed it your best-performing past emails as examples. This is the single biggest improvement – few-shot prompting with YOUR proven copy.
3. Ask for 3 subject line variants with different psychological hooks (curiosity, urgency, social proof). Then A/B test.
4. Always specify tone: “conversational but professional, like a knowledgeable friend giving advice, not a salesperson.”
5. Request the email in a specific format: hook → problem agitation → solution → proof → CTA.
Results: Our open rates went from 22% to 31% and click-through improved by 40% after adopting this AI-assisted workflow.
The irony: the emails work better BECAUSE a human is steering the AI, not despite it. Pure AI copy underperforms. AI-assisted human copy outperforms both.

hot take: the subject line step is where most people waste time. three variants is fine but if you're not testing send time alongside it you're leaving data on the table.
ok real talk - the hook to problem to proof structure works but it depends heavily on list temperature. cold list needs way more problem agitation, warm list you can cut straight to the proof.
does that change based on industry too? i'd imagine b2b cold outreach vs ecomm warm list are basically different genres at that point
one thing i'd add - after you get the draft, paste it back into the model and ask it to highlight any sentence that sounds like marketing copy. catches a surprising amount of stuff.
31% open rate is solid but curious what industry that is. we're in saas and hitting those numbers without ai assist so wondering how much is the workflow vs the list quality.
the few-shot prompting with your own copy is the real unlock here. most people skip that step and wonder why the output sounds nothing like their brand.
