Scaling a PLG Startup to an Exit with Cold Email
How we scaled a PLG client to an exit with an average of 20-50 new signups per week.
Background
Astral is a fast-growing AI tool that helps professionals automate and organize their daily workflows by combining calendar intelligence, task management, and productivity automation. Designed for knowledge workers, remote teams, and executive operators, Astral offers a seamless way to stay on top of what matters without the usual chaos of switching between apps.
With a sleek product and ambitious roadmap, Astral was ready to push outbound as a scalable user acquisition channel. Their team partnered with Cymate to turn cold email into a reliable growth engine that could deliver consistent, high-intent PLG signups.
The Situation
Astral initially faced several issues when trying to activate cold email in-house. They struggled to verify lead data effectively, which meant many of their messages never reached real decision-makers. Even when leads were correct, their emails frequently landed in spam or promotions folders - minimizing visibility and engagement.
This wasn’t Astral’s first attempt at cold outreach, but previous campaigns had failed to generate meaningful traction. Looking for a smarter and more systematic approach, they brought in Cymate to build a high-performing outbound system from scratch.
Their internal team also lacked the bandwidth to scale email volume consistently. Without proper infrastructure and deliverability protocols, it was impossible to build momentum or test at the scale required for meaningful insights.
The Solution
Infrastructure Setup
With an enormous TAM and a clear value proposition, we set out to build infrastructure that could safely scale. We spun up multiple domains and inboxes across different vendors to minimize risk and ensure long-term deliverability. This setup gave us the flexibility to send at volume while staying compliant with sending best practices.
Strategy: What Worked From Day One
From the very first campaign, we achieved high inbox placement. But what truly accelerated results was our offer - crafted specifically to match Astral’s ICP pain points. We positioned the product as an immediate upgrade for busy professionals who wanted to reclaim control of their time. This clarity and relevance drove engagement from the very start.
Why We Kept Iterating
Rather than settling for “good enough,” our team continued refining the campaign copy, targeting filters, and timing. Our mindset was not to “set and forget” but to optimize continuously. This constant iteration allowed us to unlock even better results, week over week.
The Results
4-5 new user signups per day directly attributed to cold outbound
Strong inboxing performance from day one, with consistent domain health
Repeatable campaign structure allowing ongoing A/B testing and optimization
