B2B Cold Email Campaign — Mood Board Engineering (Wellness Tech)
Email Marketing
Project Overview
Developed and implemented a full-cycle B2B cold email campaign for Mood Board Engineering — a Hungarian company that offers immersive multisensory SPA solutions based on 5D wellness technologies. The target audience includes hotel owners, wellness center managers, and private spa complexes across Europe.
My Role and Responsibilities
As an email marketer on this project, I managed the entire campaign process in collaboration with a professional graphic designer:
… Contact Database Validation — Prior to launching the campaign, I conducted a thorough check of the database: removed invalid addresses, duplicates, and undeliverable contacts to maximize deliverability and protect sender reputation.
Strategy and Copywriting — Developed the narrative and text of the email in a consultative B2B tone, built around the audience's pain point ("the sauna experience is almost always the same"), leading to a clear value proposition and CTA — a request for consultation.
Collaboration with Designer — Worked closely with the designer to create a pixel-perfect HTML email template in both light mode and dark mode for proper display in all popular email clients and on all devices.
Campaign Setup and Launch — Set up and launched the outreach sequence through Snov.io while adhering to technical requirements: SPF/DKIM, compliance with unsubscribe requirements, sender warming.
Results
Validated B2B contact database
Compelling email copywriting for decision-makers in the hospitality and wellness sectors
Responsive HTML email template (light + dark mode)
Launched outreach campaign through Snov.io

Klaviyo | Welcome Series — brand in the health and supplements niche
Email Marketing
Developed and launched a series of 6 welcome emails for a food supplement brand in the health and wellness niche — fully built and automated in Klaviyo, from strategy to live flow. Created a complete subscriber journey that guides new users from first acquaintance to first purchase within 7 days: a welcome email with a discount promo code, brand story, educational content about ingredients, social proof, helpful lifestyle content, and a final email with a deadline. My contribution includes the full architecture of the series and the setup of automation — triggers, time delays, and flow logic in Klaviyo. Worked closely with a designer on the visual design of all 6 emails — together we created a clean, branded look that aligns with the aesthetics of the health and wellness niche. The series is designed to stand out in a saturated market — with a clear content strategy behind each email and strong visual solutions. Result: Series strategy · Design of 6 emails (in collaboration with a designer) · Automation setup in Klaviyo. Niche: Health and wellness / Food supplements. Platform: Klaviyo.

Email Marketing
To announce the start of tulip bulb sales, I developed and launched a responsive promo email that directly leads users to the catalog.
What was done:
Strategy and structure — main banner with the theme "Autumn Season 2025" + clear CTA "Go to catalog".

Automated collection of contacts from Google Maps via Make.com
Data Parsing
Developed a fully automated workflow for collecting and enriching contact information about companies from Google Maps based on specified keywords and geolocation. The solution eliminates the need for manual searching and significantly speeds up the lead generation process for marketing and sales departments.
How it works:
… Data input: The user fills out a Fillout form with search parameters.
Data collection: A scenario in Make (Integromat) makes a request to the Google Places API and retrieves the company name, address, and website.
Data enrichment: If the website is found, the system extracts email addresses, phone numbers, and social media links through RapidAPI Website ContactCrawler.
Data processing: The results are cleaned, structured, and formatted into a CSV file.
Data delivery: The file is automatically uploaded to Airtable, and the application status is changed to Complete.
Key results:
Time savings: Reducing the contact collection process from hours to minutes
Scalability: Processing hundreds of records in a single run
Accuracy: Selecting only relevant domains (excluding social media and forms) to obtain valid leads
Integration: Full synchronization with Airtable for convenient tracking of applications
Technologies used:
Make, Google Places API, RapidAPI (Website ContactCrawler), Airtable, Fillout Forms

LinkedIn Scraper on n8n + Google Custom Search + Google Sheets
Data Parsing
In this project, I implemented a fully automated process for collecting LinkedIn profiles using:
n8n (no-code/low-code automation platform)
… OpenAI GPT-4o-mini for generating search queries
Google Programmable Search Engine (CSE) for scraping Google results
Google Sheets for storing the obtained data
What has been done:
Input chat: the user sends a message with the search topic (e.g., "Marketing managers in Berlin").
AI formatting: a precise search query for Google CSE is generated via GPT-4o prompt.
Pagination: a JavaScript script divides the query into pages to collect up to 500 results.
API request to Google CSE: requests are sent to Google to obtain profiles.
Filtering results: only links to LinkedIn profiles are extracted from the Google JSON response.
Saving: all unique links are added to Google Sheets (with duplicate checking).
Result:
Automatically collected over 40 unique LinkedIn profiles
Data neatly stored in the spreadsheet
Fully managed from one chat or API integration
