[{"step":"Gather your campaign data","action":"Collect [TARGET_AUDIENCE] attributes, [PRODUCT/SERVICE] details, and [PAST_CAMPAIGN_PERFORMANCE] metrics. Export audience data from your CRM (e.g., HubSpot, Salesforce) with fields like purchase history, engagement scores, and demographics.","tip":"Use your email platform's segmentation tools to pre-filter audiences before generating variations. For example, in Mailchimp, create segments based on 'last purchase date' or 'average order value'."},{"step":"Customize the prompt template","action":"Replace all [PLACEHOLDERS] with your specific data. For segmentation, use criteria like 'high-value customers', 'cart abandoners', or 'new subscribers'.

Avoid over-segmenting - 3-5 segments is ideal for most campaigns."},{"step":"Generate and refine variations","action":"Run the prompt in your AI tool (e.g., Claude, ChatGPT) to create subject lines and email bodies. Manually review outputs for brand voice consistency, then adjust tone or messaging as needed.","tip":"Use AI to generate 5-10 variations per segment, then select the top 3 based on your brand guidelines. Tools like Grammarly can help refine the final copy."},{"step":"Set up A/B testing","action":"Configure your email platform (e.g., Klaviyo, ActiveCampaign) to split-test variations. Schedule sends during peak engagement times (typically 9-11 AM or 1-3 PM local time for your audience).","tip":"For accurate results, ensure your sample size is large enough.
