AI Developer Needed for LLMs and Production AI Systems Strong opportunity for an AI developer experienced with LLMs and production-grade systems. Background in prompt engineering, model evaluation, RAG pipelines, and scalable deployment would be highly valuable.

I build email marketing systems using Klaviyo, Mailchimp, and ActiveCampaign that turn subscribers into customers and one-time buyers into repeat buyers.

My work covers email marketing strategy, automation, campaigns, segmentation, deliverability, email design, and customer retention.

I do not build random newsletters or disconnected email sequences. I create structured email marketing systems that send the right message to the right person at the right time.

What I can help you with:

📧 Email Marketing Strategy

• Email marketing audits
• Customer journey planning
• Campaign calendars
• Retention strategy
• List growth strategy
• Performance tracking
• Revenue-focused recommendations

⚡ Email Automation and Flows

I build automated email flows for:

• Welcome sequences
• Abandoned cart recovery
• Browse abandonment
• Customer onboarding
• Post-purchase follow-up
• Cross-sell and upsell
• Review requests
• Lead nurturing
• Re-engagement
• Win-back campaigns
• Subscription reminders
• Product education

Each flow is built around customer behaviour, timing, segmentation, and a clear conversion goal.

🛍️ Klaviyo Email Marketing

I build and manage Klaviyo email marketing systems for e-commerce brands.

This includes:
• Klaviyo account setup
• Email flow strategy
• Ecommerce segmentation
• Campaign management
• Shopify integration
• Dynamic product blocks
• Revenue reporting
• A/B testing
• Deliverability improvement
• Customer retention flows

📨 Mailchimp Email Marketing

I create Mailchimp campaigns, automations, newsletters, templates, signup forms, and audience segments.

I can also clean and organise existing Mailchimp accounts, fix broken automations, improve contact structure, and create mobile-responsive email templates.

🔁 ActiveCampaign Email Marketing

I build ActiveCampaign automations for lead nurturing, customer onboarding, sales follow-up, tagging, segmentation, and lifecycle email marketing.

I use behaviour-based triggers, so contacts receive emails based on what they click, view, purchase, submit, or ignore.

🎨 Email Campaigns and Design

I create clear, mobile-responsive email campaigns that match your brand and guide readers toward one main action.

My work includes:
• Promotional campaigns
• Product launches
• Newsletters
• Educational sequences
• Seasonal campaigns
• Sales announcements
• Branded email templates
• Email copy and calls to action

🎯 Segmentation and Personalisation

Strong email marketing does not send the same message to everyone.

I segment audiences based on:

• Purchase history
• Engagement level
• Website behaviour
• Customer lifecycle stage
• Product interest
• Location
• Lead source
• Subscription status

This helps improve relevance, engagement, conversions, and customer retention.

📬 Deliverability and List Health

I improve the foundation of your email marketing through:

• List cleaning
• Engagement-based segmentation
• Suppression management
• Spam-risk reduction
• Domain authentication guidance
• Bounce monitoring
• Sender reputation checks
• Unengaged subscriber management

🔗 API and System Integrations

I connect email marketing platforms, forms, calendars, databases, Airtable, Google Sheets, AI models, and custom applications using REST APIs, webhooks, and real-time data flows.

When standard email marketing tools are not enough, I can also build lightweight full-stack dashboards, admin panels, customer portals, custom forms, and email marketing control interfaces

🧰 Platforms and Tools

Klaviyo • Mailchimp • ActiveCampaign • Omnisend • MailerLite • ConvertKit • HubSpot • Shopify • WooCommerce • Zapier • Make,com • Canva • Figma • HTML Email

You will receive an email marketing system designed to improve engagement, recover lost sales, support customer retention, and generate more value from your existing audience.

📩Send me your website, current email platform, list size, and main goal. I will review your setup and recommend the highest-impact improvements for your Klaviyo, Mailchimp, or ActiveCampaign account.
