Mariusz Opalka — Expert Email Developer & Email Marketing Automation Specialist

Intelligent
Email Campaigns & Flows

Convert visitors into loyal customers with meticulously tailored automated flows. From Welcoming Series and Abandoned Carts to dynamic cross-selling algorithms constructed in Klaviyo, Mailchimp & HubSpot.

Core Flows

High-Converting Frameworks

Welcome Series

The most important flow for your brand. First impressions matter. Introduce your brand, set expectations, and convert subscribers into first-time buyers with targeted incentives.

Abandoned Cart

Recover lost revenue. Strategic follow-ups that remind users what they left behind, overcome objections, and offer timely incentives to complete the purchase.

Win-Back / Re-engagement

Re-activate dormant customers before they churn completely. Offer dynamic discounts or highlight new collections tailored to their previous browsing history.

Post-Purchase & Cross-Sell

Turn one-time buyers into loyal brand advocates. Request reviews, offer product care instructions, and cross-sell complementary AI-personalized products.

Custom Integrations

I connect your shop to ESPs via APIs, Zapier or custom n8n flows. Pass complex custom events from your systems directly to Klaviyo or Mailchimp.

Campaign Management

End-to-end management of monthly newsletters and promotional blasts. Includes strategic calendaring, A/B testing of subject lines, and deep revenue reporting.

Next-Gen Capabilities

AI Automated Mail & MCP Servers

I merge classic Email Marketing with the latest Artificial Intelligence frameworks to unlock unprecedented analysis, personalization, and productivity.

Campaign AI Analysis

Automated scripts that pull performance data from your ESP, pass it to an LLM (like Claude or GPT-4), and output actionable hypotheses, segment recommendations, and A/B test ideas directly to your dashboard.

RAG Vector Databases

Ingesting your company's product catalogs, knowledge bases, and previous best-performing campaigns into a Vector DB. This allows AI agents to instantly fetch precise knowledge and draft highly-contextual email segments automatically.

Local MCP Integration

I construct custom Model Context Protocol (MCP) servers linking your CRM directly to local AI instances. Chat securely with your own subscriber data without exporting it, entirely revolutionizing your campaign planning workflows.
