The Brief

Why ESW Company Needed a Beehiiv Newsletter Migration

Migrate ESW’s newsletter system from Mailchimp to Beehiiv, preserving subscriber segmentation and engagement.

Implement a comprehensive B2B email marketing strategy featuring brand-aligned templates, detailed audience segmentation, automated email flows, lead magnet integration, and ongoing performance tracking to enhance lead generation and establish brand authority.

ESW recognized the need to upgrade its email marketing platform to better meet the demands of scalable, targeted B2B communications. Migrating from Mailchimp to Beehiiv allowed for greater customization, advanced segmentation, and a stronger automation framework. We spearheaded the technical migration and template design, ensuring clean integration with ESW’s existing website and CRM systems, while ESW’s marketing team handled subscriber data migration and content strategy. This transition strategically positioned ESW as a recognized authority in Microsoft consultancy by enabling personalized customer journeys, sophisticated lead nurturing, and multi-channel touchpoints through well-crafted newsletters and lead magnets. The project combined technical precision with marketing insight to strengthen audience engagement and conversion effectiveness.

Before and After

Before and After: ESW Company’s Homepage, Examples and Contact Pages

Left side: the site as the Wayback Machine captured it in Apr 2025, on WordPress + Mailchimp. Right side: the live WordPress + Beehiiv site, captured Oct 2026.

Wayback never preserved the stylesheets for the April 2025 inner pages of eswcompany.com, so the examples-page “before” shows unstyled markup.

Homepage Before and After: A Hero That States the Offer, Rating and Booking Button

The April 2025 homepage opened with “Your Digital Transformation Starts Today” over a short services line and one Schedule Consultation button. The live homepage leads with a six-topic tag line, a headline about a dedicated Microsoft 365 team, two buttons (AI readiness score, strategy call), a Microsoft Partner badge with Google rating, a client quote and a client-logo strip.

Why it matters. Our work was to place the Beehiiv sign-up at the homepage, footer, blog sidebar and mega menu without disturbing these existing flows.

Examples Page Before and After: Filter Chips and a Case-Study Grid

The archived December 2024 page renders as raw markup: a nested text menu, a Request Consultation button and a category list. The live page shows the same categories as filter chips (All, AI Agents, Banking / Finance, Construction, Copilot, Defense, Dynamics 365 and more) above a grid of case-study cards with screenshots and titles.

Why it matters. The Beehiiv embed replaced the Mailchimp form on blog and content pages, the main inner-page touchpoint in the brief.

After: Oct 2026, live, eswcompany.com/ms-power-apps-sharepoint-office-365-examples/

Contact Page Before and After: Same Form, New Phone Number and a Response-Time Tag

In November 2024 the contact page had a teal panel reading “Speak with our Team” next to a seven-field Contact Us form, with a review pop-up in the corner. The live page keeps the layout, retitles it “Speak with our US Team”, adds a Rapid Response Time pill and an arrow into the form, and the header number changes from 833-957-3062 to 833-923-3197.

Why it matters. The brief required Beehiiv forms to be integrated without disrupting existing user flows; the contact form is unchanged.
