About SI Staffing
SI Staffing helps employers fill labor needs across distribution, logistics, light industrial, and commercial roles. Yuri Kovalenko also operates business brokerage and investment ventures, giving his team several offers that can benefit from repeatable outbound.

The challenge
A process that could prove itself before scaling
Yuri wanted a dependable way to create sales opportunities across several businesses.
The team had tested other vendors, but wanted stronger response rates and a process they could scale only after the numbers showed that it worked.
The solution
Sending capacity paired with campaign support
Mailscale helped the team launch and manage outbound campaigns, review performance, and improve how interested prospects moved into follow-up. The platform created sending capacity while the team supported campaign execution and reply handling.
“I trust your process.

The results
50 interested leads from 23,000 sends
The result gave SI Staffing a clear base for building a repeatable lead-generation process. Yuri's team also reported that the response rate was better than campaigns run with other vendors.
“Your campaigns are getting results.
“We do start campaigns with other vendors. This one is much better because of the response rate that we are getting.
A note on the result: The call directly verifies 50 positive replies and 23,000 sends. These are presented as qualified, interested leads—not booked meetings or revenue.
What they liked
A process built to test, improve, and scale
Even with access to other systems, Yuri valued Mailscale's process and wanted to focus on proving it before expanding.
