CASE STUDY · CONSULTING

    Conversion-focused one-pager with automated lead intake.

    A consultancy wanted a professional site that immediately inspires confidence and directs leads to the right inbox. We built a fast one-pager with a contact form that automatically sends messages from their own domain.

    THE CHALLENGE

    A business card was no longer enough. Leads needed to come in immediately.

    Old platform didn't feel professional

    Slow loading times and an outdated look undermined the conversation that sales should have triggered.

    Contact form sent from a generic domain

    Messages arrived from a no-reply address from an external provider, which hurt brand experience and deliverability.

    No clear positioning

    Visitors didn't understand within 5 seconds what this company solves and for whom.

    Leads came in fragmented

    Emails, phone calls, and LinkedIn messages gathered in different places without central follow-up.

    OUR SOLUTION

    One sharp screen + one reliable lead pipeline.

    We built a one-pager with clear positioning and a contact form that emails via a server endpoint from their own domain, straight to the right inbox.

    Server-side mail API

    Dedicated contact endpoint that validates input and sends a structured email server-side.

    Custom domain as sender

    Emails arrive from their own domain, so they look trustworthy and land in the inbox more often.

    One central inbox

    All leads land in one central inbox in a standardised email format, ready for follow-up.

    One-pager with section flow

    Clear positioning, services, expertise, and contact on one scrolling page.

    Fast & SEO-ready

    Static rendering, clean HTML, and good core web vitals, so it shows up in search engines from day 1.

    Easy to edit

    Content is centrally managed so text adjustments can be made without a developer.

    THE APPROACH

    Live in 3 phases.
