To execute the strategy, the brand partnered with MyNewsletter — Brazil’s first boutique agency focused exclusively on building newsletters for companies, founded by Fernando Kaloustian. The result? In just two months, the newsletter became a profitable revenue channel generating over 2× its operational costs, proving the power of email for DNVBs and E-commerce brands. ## Challenge: Guday wanted a newsletter that could: - Deepen brand trust - Build long-term customer relationships - Drive repeat purchases and higher LTV - Validate product demand - Avoid aggressive, hard-sell DTC tactics But they lacked: 1. Internal bandwidth to run a consistent, high-quality email program. 2. A clear content strategy that balanced value with subtle sales. 3. The right platform to create on-brand newsletters, integrate analytics into their CRM, and scale efficiently. They needed a partner who understood newsletters deeply and a platform built for modern media-quality email. ## Solution: Guday teamed up with MyNewsletter and built a newsletter program powered entirely by beehiiv, focusing on strategy, storytelling, and data-backed execution. ### 1\. Agency partnership with a creator-led edge MyNewsletter transitioned from an educational project to a full-service agency as demand grew. After years of knowing Guday’s founding team — and following the brand closely — Kaloustian stepped in to design, launch, and operate Guday Talks, their weekly newsletter. ### 2\. Email strategy built around an 80/20 content mix The team adopted a clear editorial framework: - 80% education: fitness insights, nutrition explainers, wellness guidance - 20% subtle promotion: product mentions woven into valuable content Instead of aggressive selling, Guday leaned on education + storytelling, expanding on the topics Manuela already covered on Instagram. ### 3\. beehiiv as the operating system After testing nearly every major platform, Kaloustian chose beehiiv for: - Robust analytics that feed directly into Guday’s CRM - Easy design customization for branded, professional newsletters - Integrated features (referrals, recommendations, monetization) supporting long-term growth This allowed MyNewsletter to launch at speed — and iterate quickly. ### 4\. Weekly cadence supported by a built-in audience Guday entered the market strong, with 100,000+ existing E-commerce subscribers already opted into communications. This gave the newsletter immediate traction. From there, MyNewsletter managed content planning, writing, design, analytics, and performance tracking. ## Results: Within the first two months, Guday saw: - 45% average open rates - High subscriber engagement and strong qualitative feedback - Product conversions that _surprised both the agency and Guday’s founding team_ - More than 2× ROI from newsletter-driven sales compared to the combined cost of beehiiv + MyNewsletter The newsletter quickly became a high-impact, high-ROI channel for a brand projected to reach R$80M (~US$15M) in annual revenue. ### Lessons Learned: Kaloustian attributes the success to three major drivers: 1. A validated product with real demand 2. An engaged creator (Manuela) with a loyal community 3. A value-first newsletter strategy supported by beehiiv’s tooling The team now plans to: - Launch a referral program - Integrate beehiiv + Shopify to onboard new customers automatically - Conduct deeper audience research - Use email not only for retention, but customer acquisition ## Related Case Studies ![How AdQuick Scaled Industry Sponsorships with beehiiv's Ad Network](https://images.prismic.io/beehiiv/Z_VpXHdAxsiBwdKG_adquick.png?auto=format,compress) ### How AdQuick Scaled Industry Sponsorships with beehiiv's Ad Network Solving scale and visibility challenges in B2B marketing [ Read Case Study → ](/case-studies/adquick) ![How Particle for Men Generated a 1.73 ROAS Through Newsletter Ads](https://images.prismic.io/beehiiv/abfLOrbci2UF6CEY_Untitleddesign-34-.png?auto=format,compress) ### How Particle for Men Generated a 1.73 ROAS Through Newsletter Ads Scaling newsletter advertising to 8.3M readers while achieving 809 conversions with beehiiv [ Read Case Study → ](/case-studies/particle-for-men) ![The Founder Who Turned His 400k+ Newsletter Into a Negative CAC Machine](https://images.prismic.io/beehiiv/afL59cBOoF08xfCT_Untitleddesign-36-.png?auto=format,compress) ### The Founder Who Turned His 400k+ Newsletter Into a Negative CAC Machine How Open Source CEO pioneered model where newsletter ad revenue offsets customer acquisition costs with beehiiv.
