Stop Writing Welcome Flows from Scratch
Writing an entire welcome series flow from a blank document is painful. Most brand owners stare at a cursor for two hours, put it off, and end up leaving money on the table. Your welcome flow is the highest-earning automation in your Klaviyo account, so getting it live quickly matters.
You can use ChatGPT (GPT-4o works best) to script the initial draft of your entire welcome sequence. The trick is avoiding lazy, single-shot prompts that generate generic marketing fluff.
If you dump in a vague request like "write me a welcome email", you will get useless copy. That is a mistake. You need a sequential research and prompting framework that feeds the model the right context before it writes a single word.
Phase 1: Force ChatGPT to Research Your Brand
Before asking for email copy, you must ground the AI in your actual business data. I start by opening a fresh chat and identifying the target brand immediately.
First, state the exact store URL and tell ChatGPT that this specific chat will be dedicated solely to scripting email marketing flows for this company. Next, prompt it to crawl the website to extract core brand pillars: target market, brand voice, mission, and product lines.
Follow that up with a third prompt asking it to specifically find your top-selling products, customer reviews, current offers, and educational resources or blog posts on the site. If your bestsellers are not obvious on the homepage, list them manually in the prompt. Always ask the model to confirm what it found before proceeding to the actual writing phase.
Phase 2: Set the Klaviyo Technical Rules
Once the model understands your brand, you need to establish guardrails. Most AI tools write emails that read like blog posts or corporate newsletters unless you restrict them.
I feed ChatGPT a strict formatting prompt covering structural rules and Klaviyo-specific requirements:
- Dynamic syntax: Tell it to use Klaviyo merge tags (like first name tags) where personalisation is needed.
- Length and layout: Specify concise sections, punchy headers, clear body copy, and prominent call-to-action buttons.
- Tone consistency: Instruct it to match the tone pulled from your live website.
- Pacing: Instruct the model not to write anything yet until you provide the specific email brief.
Always tell ChatGPT to confirm it understands these constraints and to wait for your command. AI models have a habit of rushing ahead and spitting out generic copy before you have provided the individual email parameters.
Phase 3: Prompting Email by Email
Do not ask ChatGPT to write all five or six emails in your welcome series at once. In my experience, batching the entire series into one prompt degrades the quality of the copy fast. You get far better results feeding it one detailed brief per email.
For Welcome Email 1, your prompt needs to include specific variables:
- Primary incentive: The exact discount code (for example, 10% off with code WELCOME10).
- Key collections: Two or three bestselling product collections to feature.
- Brand mission: The core unique selling proposition (USP) that separates you from competitors.
- Social proof: A short testimonial or customer rating snippet.
Once you send this detailed brief, ChatGPT will output a clean layout with subject line options, preview text, header copy, body paragraphs, and button copy tailored to that exact offer.
Turn Copywriters into Editors
Let me be clear about one thing: this process produces version one of your copy. You should not blindly copy and paste raw AI output straight into your Klaviyo templates without human review.
This workflow gets your copy roughly 80% of the way there in a fraction of the usual time. The real benefit here is operational efficiency. If you work with a copywriter, you no longer need them to draft every sequence from scratch.
You can hand them this AI-generated foundation and have them refine the hooks, tighten the phrasing, and ensure the brand voice is unmistakably yours. Paying someone to edit and polish strong drafts is far faster and considerably cheaper than paying for net-new copy across every flow.
Final Thoughts
ChatGPT is only as good as the context you feed it. By forcing the model to research your store, obey Klaviyo formatting rules, and draft emails one prompt at a time, you can script an entire high-converting welcome series in an afternoon. Use the AI to eliminate the blank page, then apply human editing to dial in the final details.
