"Make me a Black Friday campaign." It's the most common request a generative AI gets — and the one that delivers the worst results. Not because the AI is bad, but because you just asked it to guess your business, your offer, and your tone in six words.
Amanda IA can generate a full campaign — copy, subject line, call to action, even a proposed image — starting from an idea. But the quality of the output depends on the quality of the prompt. The good news: putting together a good prompt takes two minutes and follows a simple structure you'll be able to reuse forever.
Think of the prompt as the brief you'd hand a new copywriter: the better you explain what you want — and what you don't want — the fewer rounds of back-and-forth you'll need later. AI amplifies your clarity… or your vagueness.
Why the prompt changes everything
Amanda generates the draft, but you're still the one in charge: you review, edit, and approve. Nothing goes out without your sign-off. So the goal isn't "let the AI do it all" — it's getting to a solid starting point faster and spending your time polishing, not staring at a blank page.
A vague prompt gives you back something correct but interchangeable — it could work for any business on earth. A well-built prompt gives you back something that already sounds like your brand and pushes toward a concrete action.
The 7 pieces of a good prompt
These seven pieces turn a generic prompt into one that actually delivers. They don't need to be paragraphs — one line each is enough.
- Goal. What you want to achieve. "Sell the weekend combo" isn't the same as "win back customers who haven't bought in 60 days."
- Audience. Who you're talking to. "Customers who already bought" isn't written the same way as "people who just subscribed."
- Offer. The concrete what: the discount, the launch, the benefit. Be specific ("2-for-1 Saturday and Sunday" beats "weekend promo").
- Tone. How you want to sound: warm, professional, playful, formal. If you have a Brand Kit loaded, Amanda already respects your voice and your colors.
- Context. What the AI has no way of knowing: that you're a neighborhood café, that it's low season, that you're competing with the chain on the corner.
- Expected action. What you want the reader to do: book, buy, reply. One action per campaign works better than three.
- Constraints. What you don't want. This piece, often forgotten, is one of the ones that improves the result the most: telling Amanda where the boundaries are keeps the draft from drifting somewhere that isn't your brand.
Constraints: tell it what you don't want too
Giving instructions "in the negative" guides the AI just as much as instructions in the positive. Some phrases you can drop in as-is:
- "Don't use words like unmissable or last chance."
- "Don't promise guaranteed results or figures we can't back up."
- "Avoid sustained caps and strings of exclamation points."
- "Don't sound like a chain — keep a neighborhood tone."
- "Don't attack self-esteem or create insecurity."
Two optional extras that pay off: ask for an image ("generate a photo of a sidewalk table, warm afternoon light, premium look") and give it a brand tagline to include, if you have one. Neither is mandatory, but both elevate the result.
A real example, step by step
Let's compare two prompts for the same business: Palermo Café, a coffee shop looking to boost weekend reservations.
Vague prompt:
Write an email to promote the coffee shop on weekends.
Amanda comes back with something polished but generic — it doesn't sell your café.
Prompt built from the pieces:
Goal: reservations for a Saturday-and-Sunday promo. Audience: customers who've visited before. Offer: 2 coffees + 2 pastries, 20% off if booked before Friday. Tone: warm and neighborhood-feel, no chain vibe. Context: boutique café with sidewalk seating. Expected action: click "Book my table." Constraints: no "unmissable" or "last chance."
With that context, Amanda proposes a subject line, a preheader, a body with just the right tone, and a clear CTA — plus a subject line variant to choose from. That same prompt, complete and ready to copy, is included below among the six examples by industry.
Six examples by industry to copy and adapt
Every business asks differently. These six examples are ready for you to copy, swap in your own brand and offer, and test. Notice how tone and constraints shift by industry — and how the last one, adventure tourism, shows a looser variant: no constraints or brand tagline, with a few emoji fitting for that segment. You don't always need all 7 pieces — use whichever ones your campaign needs.

Your prompt
I need an email marketing campaign to promote a course called Excel for Sales Management.

Offer: a hands-on 4-class course with real exercises, downloadable templates, and a certificate of completion.

Expected action: get them to click "Reserve my spot."
Image: someone working on a laptop with tidy charts and spreadsheets; a professional vibe of productivity and hands-on learning.
Constraints: avoid heavy academic language and don't promise magic results.

Adventure travel
Your prompt
I need an email marketing campaign for an adventure travel agency for young travelers called Ruta Salvaje.
Goal: fill the spots for the next weekend trekking + rafting trip.
Audience: 18-to-30-year-olds who love the outdoors, travel in groups, and book from their phones.
Offer: a 2-day trip (trekking, rafting, and camping) with a discount for groups of 4 or more; limited spots.
Tone: energetic, casual, motivating, like talking to a friend; use a few emojis sparingly (🏔️ 🎒 🔥) and add a couple of hashtags at the end.
Context: we're competing with last-minute trips organized over social media; our edge is safety, certified guides, and group energy. Almost everyone opens the email on their phone, so think mobile-first.
Expected action: get them to book their spot before it sells out ("Reserve my spot").
Image: a young group at a mountain summit at sunrise, backpacks and smiles, golden light, a feeling of achievement and adventure.
A looser variant: no constraints or brand line, with emojis and slang typical of this segment. You don't always need all 7 pieces — adjust the request to what your campaign actually needs.

Refining without starting from scratch
The first draft is almost never final, and you don't need to rewrite the whole prompt. You refine it through chat, in plain language:
- "Make it shorter, so it fits on a phone screen."
- "Add a sense of urgency, but without shouting."
- "Give me three more casual alternative subject lines."
Amanda also generates alternative subject lines and preheaders for you to test, and if you've loaded your Brand Kit, it keeps your identity consistent across every variant. Once the result feels right, it's ready for review — and it only goes out once you approve it.
Watch your generations
At arrobaMail, every AI operation counts as a generation. A clear prompt gives you a better draft on the first try, so you rely less on regenerating. Two habits that pay off:
- Put the prompt together using the pieces above before you ask (you can use the Prompt builder, which assembles the instruction for you).
- Refine with targeted tweaks instead of regenerating everything from zero.
The difference is in the prompt
Amanda IA can generate a full campaign from a simple idea, but when the prompt includes goal, audience, offer, tone, context, expected action, and constraints, the result improves noticeably. It's not about writing long prompts out of obligation — it's about giving it the information it needs to make better creative and business decisions. AI speeds up the path; the decision and the final edit are still yours.
