Overview
Kai Footprint helps businesses appear as recommended options inside ChatGPT, essentially providing SEO for AI. As the company grew, cold email became a core channel for driving awareness and customer acquisition.
The team, led by founder Grayson Faircloth, sends thousands of emails every week and manages a large-scale outreach infrastructure with more than 2,000 active email accounts, continuously adding new ones to keep up with demand.
The Challenge
The company experimented with a variety of providers, including several SMTP based platforms. While some offered decent performance, most came with poor deliverability, frequent disconnections, or heavy maintenance requirements.
For a company sending such high volumes, even small disruptions in inbox performance or connection stability meant lost opportunities. The team needed a reliable, scalable infrastructure that could support thousands of accounts without compromising results.
The Switch to Aerosend as an Alternative
After testing multiple platforms, Kai invested heavily in Aerosend, describing it as the only setup that consistently produced measurable results. The onboarding process was quick, and the performance exceeded expectations. Aerosend soon became the backbone of Kai’s cold email operations, enabling large-scale sending with stable deliverability and minimal manual effort. While the team still uses Gmail for diversification, Aerosend now powers the majority of their outbound volume.
The Results
With Aerosend, Kai achieved reliable, repeatable performance across all campaigns. Deliverability rates remained high even with heavy daily volumes, while positive reply rates surged. On average, the team generates hundreds of positive replies each week, with Aerosend delivering up to ten times the success rate of other SMTP solutions.
Aerosend’s consistent performance also eliminated the need for constant troubleshooting or mailbox reconnections, a frequent issue with other providers. The infrastructure simply works, allowing Kai to focus on refining offers and scaling outreach instead of managing backend systems.
“Aerosend has been the only SMTP platform that has actually produced results for us. Others disconnect or underperform, but this just works. It’s stable, consistent, and has powered our best campaigns at scale.” – Grayson Faircloth, Founder, Kai Footprint
