The ChallengeEndless Roadblocks to Breakthroughs

Each brand faced distinct challenges.

AnimeInJapan & FreeBettingReviews: Started with zero email list, no funnels, and no newsletter strategy requiring a complete foundation for audience growth and communication.

Halfagoal & ShinKawamoto: Inherited massive cold databases (30k–50k) plagued with low engagement, no segmentation, DNS errors, and poor deliverability—demanding a full system overhaul.

What I DidBuilding Solid Email Systems

I built complete email infrastructures tailored to each brand’s goals and voice.

I created opt-in forms, landing pages, and lead captures across web and social platforms, then designed branded email templates in Figma and Canva to establish consistency. From there, I built automated flows, including welcome series, promos, and re-engagement campaigns while segmenting subscribers by source, behavior, and activity. To maximize reach, I scraped and engaged cold leads with targeted outreach, and strengthened operations by implementing CRM tagging and full campaign visibility using Mailchimp, Bitrix24, SendX, Sendinblue, Mailerlite, Klaviyo.

On the technical side, I configured SPF, DKIM, and DMARC for all sending domains, resolved blacklist issues, and carefully warmed cold domains to restore trust. I audited every campaign for spam triggers, subject lines, and preview text, ensuring messages passed filters without losing impact. Consistently, I maintained deliverability scores above 90 using Mail-Tester and GlockApps, while setting up ongoing health monitoring routines to keep domains and campaigns performing at their best.

The ImpactZero to High-Performance

I turned disconnected or nonexistent email efforts into full-fledged ecosystems that now drive traffic and conversions, enable B2C & B2B outreach, and strengthen community loyalty and retention.

For AnimeInJapan, I built an audience of more than 15,000 subscribers in just six months starting from zero. Weekly campaigns now average over 38% open rates, supporting affiliate promotions, site traffic, and overall brand growth.

With FreeBettingReviews, the list grew from 5,000 to more than 20,000 in a single year. Nearly 70% of B2B partnerships are now initiated through email funnels, while thoughtful segmentation has sustained strong inbox placement and subscriber trust.

For Halfagoal, cold open rates climbed from about 20% to over 80%. More than 63% of a 50,000-contact cold database converted into engaged readers, with segmentation fueling promotional, seasonal, and editorial campaigns.

And with ShinKawamoto, optimized email funnels boosted eBook downloads and paid purchases. Nearly half of cold contacts 46% were converted into active users, supported by stable domain health and a stronger sender reputation.

Client FeedbackTrusted Partner Proven Every Time

“Clark has worn many hats with us, and when he took over email, it was like he’d been doing it for years. He cleaned up our lists, solved deliverability issues, and made our emails actually work. He’s the kind of person who figures things out fast and does the job with heart. Honestly, a rare find.”

“We started from zero with AnimeInJapan, and Clark handled everything; growing our list, designing campaigns, and making sure everything ran smoothly. He always found ways to add value without overcomplicating things. With ShinKawamoto, his email work made a real difference in how we connect with our readers and sell our ebooks. People are actually excited to hear from us now.”
