How we helped Writesonic 131% increase in signups—powered by cold outbound

The challenge

With $2.6M raised and product-market fit secured, Writesonic wanted to scale fast. But relying heavily on paid channels like Google, Facebook, and TikTok left them with unpredictable CPAs and rising acquisition costs.

They needed a second growth engine: one that would consistently deliver qualified signups for both Writesonic and ChatSonic at scale, without blowing the budget.

That’s where Leadamax came in.

Our approach

✅ Targeted List Building at Scale
We mapped Writesonic’s ideal personas: startups, agencies, content marketers, e-commerce owners, and founders. Using Scrapeamax + Clay + Apollo, we scraped ultra-targeted data from the right industries and countries.

✅ Cold Email Engine Deployment
We set up a full cold outreach system: inbox warm-up, domain rotation, deliverability optimization, and sequenced messaging flows to engage leads at scale.

✅ Offer + Message Testing
We applied our version of ad testing to cold email. We rapidly tested offers (free trial of Writesonic and ChatSonic), subject lines, and CTAs to optimize for demo bookings and trial signups.

✅ Conversion-Focused Sequences
We didn’t just book demos—we optimized follow-up frameworks to convert trials into paid accounts.

✅ Always via cold outbound
Every result came from our cold outbound engine. No paid spend. No retargeting. Just data + copy + process.

The results

✔️ 131% increase in signups vs. baseline
✔️ 350% revenue growth during engagement period
✔️ 15% decrease in cost per acquisition
✔️ Consistent daily lead flow + global pipeline growth

With Leadamax, Writesonic transformed cold email into a predictable revenue-generating machine that scaled alongside their paid efforts.
