Setting up Emmie for writing professional emails

Four quick steps. This is the friction-reducer before you start writing.

1. Sign up for Sintra and select Emmie as your AI email marketing helper from the Helpers list.
2. Set up Brain AI. Upload your brand guidelines, tone of voice notes, product or service details, and any strong past email examples. Takes around 5 minutes. This is what makes Emmie's output sound like your team, not a generic AI.
3. Know your email type and goal. Before prompting Emmie, decide what kind of email you're writing (welcome, follow-up, campaign, win-back) and what action you want the reader to take. The clearer the brief, the sharper the output.
4. Run your first email. Describe the email type, your audience, and the goal in chat, then ask Emmie to write it. Copy the output into your email platform and send it yourself.

How to write professional emails with Emmie in 8 steps

Each step below covers a different email type Emmie writes, with the exact prompt to send. Run them in sequence to build a full email program, or jump to the email type you need right now.

Step 1. Write a professional business email

Emmie drafts clear, professional emails for any business context (introductions, updates, requests, follow-ups) using the tone and details you provide in Brain AI.

Prompt: "Write a professional email to [recipient / audience]. The purpose is [goal]. Key points to include: [point 1], [point 2], [point 3]. Tone: [formal / conversational / warm]."

Output: A structured professional email with subject line, opening, body, and a clear closing. Ready to copy into your email client.

Step 2. Write a welcome email

Emmie crafts a welcome email that introduces your brand, confirms what the subscriber signed up for, and sets a warm, confident first impression from day one.

Prompt: "Write a welcome email for new subscribers to [brand / newsletter name]. Introduce our brand, highlight [key value or benefit], and encourage them to [next action]."

Output: A friendly, on-brand welcome email with a subject line that reflects the sign-up context and a body that moves the reader toward their first action.

Step 3. Apply the right email writing format

Emmie structures every email with a clear subject line, a focused opening that states the purpose, a concise body, and a single call to action. The email writing format that gets read and acted on.

Prompt: "Write a [type] email for [audience]. Subject line should communicate [benefit or urgency]. Body should cover [key message]. CTA: [action you want reader to take]."

Output: A fully formatted email with subject line, preview text suggestion, body paragraphs, and CTA. Structured to the professional business email format.

Step 4. Build an abandoned cart sequence

Emmie writes a multi-step abandoned cart flow with escalating messaging (a gentle first reminder, a stronger follow-up, and a final email with an incentive) ready to load into your email platform.

Prompt: "Create a 3-step abandoned cart email sequence for [store / product type]. Include a reminder in email 1, urgency in email 2, and a [X]% discount offer in email 3."

Output: Three complete emails with individual subject lines, body copy, and CTAs. Structured as a sequence with logical escalation between each send.

Step 5. Write a post-purchase follow-up

Emmie writes the email that goes out after a customer buys (thanking them, requesting a review, offering support, or suggesting a related product) in a tone that feels personal, not automated.

Prompt: "Write a post-purchase follow-up email for customers who just bought [product]. Thank them, ask for a review on [platform], and suggest [related product or next step]."

Output: A warm, specific post-purchase email with a subject line and a clear ask. Phrased to encourage action without feeling transactional.

Step 6. Plan and write a campaign

Emmie maps out a full email campaign (subject themes, send schedule, and content direction for each email) then writes the individual emails once the plan is approved.

Prompt: "Plan a [X]-week email campaign for [goal, e.g. spring sale / product launch / re-engagement]. Suggest the schedule, subject themes, and what each email should focus on."

Output: A campaign plan with a send schedule and a brief content direction for each email. Ready for you to approve before Emmie writes the individual sends.

Step 7. Write newsletter content

Emmie generates newsletter copy (lead story, secondary sections, and a closing CTA) keeping the writing fresh and relevant without you starting from a blank page every issue.

Prompt: "Write a newsletter for [brand]. Lead story: [topic]. Secondary section: [topic]. Sign-off: [tone or message]. Audience: [description]."

Output: A complete newsletter draft with a subject line, structured sections, and a closing CTA. Ready to paste into your email platform and send.

Step 8. Write a win-back email flow

Emmie builds a win-back sequence for lapsed customers, acknowledging the time since their last purchase, offering a reason to return, and giving them an easy next step to take.

Prompt: "Write a win-back email flow for customers who haven't purchased in [X months]. Acknowledge the gap, offer [incentive], and include a clear CTA to return."

Output: A 2 to 3 email win-back sequence with subject lines and body copy that escalates from a soft re-introduction to a direct incentive offer.

Writing emails manually vs. with Emmie

A note on output quality. Emmie produces a strong first draft, but always review the email against your brand voice, current offers, and segment context before sending. AI can structure an email sharply. It can't catch context only you have.

Tips for writing better professional emails with AI

• Load Brain AI with 3 to 5 of your best-performing past emails before you start. Emmie uses these as tone and structure references, so every new email feels like a natural extension of what already works for your audience.
• State the single goal of the email in your prompt, not a list of goals. "Get the reader to book a call" produces sharper output than "inform, build trust, and convert." One email, one action.
• Tell Emmie the audience's current state, not just who they are. "Customers who bought 6 months ago and haven't returned" gives Emmie the context to pitch the right tone, not just the right words.
• Use Emmie's campaign planning step before writing individual emails. Getting the sequence structure and theme approved first means each email has a clear role and the overall flow makes sense before any copy is written.
• For high-volume sends or multiple segments, brief each email separately. If sending to 4 different audience segments, run a separate Emmie prompt for each with segment-specific context. The extra 10 minutes of prompting produces noticeably higher relevance across all versions.
