Project details
I will create the design. Then, I will code the approved design into a Marketo email template.
The individual modules for the Marketo template will be programmed using the Marketo programming language. Thanks to this, the email template will be easy to edit while creating email campaigns. I will also provide a link to Litmus tests for this template.
The tests will be conducted on about 90 of the most popular email clients. Please contact me before purchasing this project to discuss the project and the final price, which depends on the design's complexity. The price mentioned refers to an email template consisting of 3 modules, which would be coded using hybrid coding - with such coding, the email template is mobile responsive on all devices.
I have access to stock images, which will be incorporated into the email template I create. As a graphic designer specializing in digital and email marketing, I ensure that each design is optimized for both regular and dark mode viewing, enhancing visual appeal and effectiveness.

Job Success
Opole, Poland - 7:58 pm local time
With 15+ years of experience, 4,000+ projects delivered for 1,900+ clients worldwide, I build production-ready email systems - not just templates - combining clean HTML/CSS, lifecycle automation, marketing strategy, deliverability expertise, and AI-driven workflows under one roof. Top Rated Plus on Upwork with $700K+ in earnings.
What I do:
1. Email Development (Core)
Custom HTML/CSS email builds - mobile-responsive, dark-mode-ready, cross-client tested. I work across Mailchimp, HubSpot, Salesforce / Pardot, Marketo, Klaviyo, ActiveCampaign, Campaign Monitor, SendGrid, and Iterable. In 2015, Mailchimp recognised me for identifying and fixing critical rendering bugs in their templates. Certified Mailchimp Partner.
2. Email Marketing Strategy & Execution
End-to-end email marketing - audits, campaign planning, segmentation, lifecycle automation (welcome, nurture, re-engagement, winback), A/B testing, and performance optimisation. I build scalable, compliant email programs with predictable long-term performance. I handle both strategy and execution end-to-end.
3. AI Architecture & Intelligent Automation
I build AI-powered audit and automation systems connected directly to your ESP/CRM via MCP servers. AI analyses your flows, campaigns, deliverability, and engagement data in real time - producing structured audit reports and prioritised fix lists. Examples: automated Klaviyo flow audits with copy rewrites, real-time deliverability monitoring, and engagement scoring. I also build RAG MCP servers that let AI reference your internal docs, brand guidelines, and performance history during audits and content generation.
4. Front-End & Automation Development
Custom applications, internal tools, dashboards, and integrations using JavaScript, Python, React, Google Apps Script, and n8n. I connect CRMs, ESPs, databases, Google Sheets, and APIs into unified automated workflows.
