AvoraGrowth is a B2B growth partner focused on cold email outreach for local businesses in the US. Founded by Alexander Yevtushenko.
Alexander Yevtushenko describes himself as a sophisticated aggressor in the outbound space.
He builds AI-powered revenue engines that operate like enterprise systems, with human-first messaging frameworks and high-velocity infrastructure behind every campaign.
In Q3 and Q4 of 2025 alone, AvoraGrowth generated over $2 million in pipeline for its clients. The company is now on pace to reach $4 million in the following period. It works with more than 20 active clients, and 90% of them run on Smartlead.
This is how they built it.
Alexander built AvoraGrowth around a clear thesis.
Local businesses have real revenue potential. They often have strong operations, loyal customers, and a genuine ability to deliver.
What most of them have never had is a structured, high-performance outbound system. While larger companies invest heavily in outbound infrastructure, dedicated SDRs, and CRM integrations, local businesses are typically left to figure it out with far fewer resources.
AvoraGrowth was built to close that gap.
The opportunity Alexander saw was not just in sending more emails. It was in building an outbound engine that could operate with the same rigour as an enterprise sales system, at a price point and operational structure that made sense for the kinds of businesses he was serving.
That meant tight deliverability management, automated lead routing, AI-assisted reply handling, and a client-facing experience that felt professional from day one.
Cold email was the primary channel because the math supported it. You can reach a large number of prospects with messaging that still feels relevant and personal. You can test, iterate, and scale based on real performance data. And with the right infrastructure, you can do all of that without the operation becoming unmanageable as it grows.
When you are running outreach across 20-plus active client accounts, the challenges that matter most are rarely about individual campaign tactics. They are about the infrastructure holding everything together.
The biggest risk in cold email is scaling faster than your reputation can support. Volume goes up, inbox placement goes down, and results disappear before anyone has identified the cause.
For AvoraGrowth, this was not just a technical concern. Deliverability directly determines whether clients see results.
An agency whose entire value proposition is booked calls and pipeline cannot afford to have emails landing in spam folders across a growing number of accounts.
Managing deliverability reliably across 20-plus clients, each with their own sending domains and inbox setups, required infrastructure that could handle that complexity without constant manual intervention.
AvoraGrowth does not run campaigns in a black box. Clients need to see what is happening with their outreach, and they need a way to respond quickly when an interested lead comes in.
That creates a real operational challenge. The platform serving clients needs to be straightforward enough for a business owner to navigate on their own, without requiring the agency to explain it every time. And it needs to give clients the access and visibility they want without exposing them to data or operations that are not relevant to them.
At scale, every manual step becomes a bottleneck. Campaign uploads, reply handling, lead routing, performance reporting across accounts: if any of these requires hands-on effort for each client individually, the operation stops scaling cleanly.
AvoraGrowth needed a way to grow the client base without growing the operational overhead at the same rate.
Alexander is direct about this: Smartlead's warm-up pools are the strongest he has tested across all tools.
For an agency sending across dozens of client inboxes, the first two to three weeks of a new domain's life determine whether that inbox builds a healthy sending reputation or gets flagged early.
Smartlead's warm-up infrastructure handled this reliably across every client account, giving AvoraGrowth the foundation needed to scale send volume without watching deliverability degrade.
The pool quality matters as much as the mechanism. Smartlead's warm-up pool consists of verified, high-reputation mailboxes generating real engagement signals. That makes the reputation-building process more durable and less likely to unravel when campaigns go live.
A major part of AvoraGrowth's competitive advantage is automation.
Using Smartlead's API, the team built a direct integration between campaign activity and GoHighLevel. The moment a lead shows genuine interest in a client's campaign, that lead is automatically pushed into the client's pipeline as a new opportunity, complete with the contact details and context needed to book a call, send a quote, or schedule a follow-up.
"We basically connected Smartlead with Go High Level. We just have a simple automation where the lead comes in, it's put as a new lead in the opportunities tab in the pipeline we've created, and they can call them through there."
This is the kind of system that lets an agency scale client count without a proportional increase in operational headcount.
At $29 to $30 per client, Smartlead's sub-account model is the most cost-effective white-label setup Alexander has found across any platform.
Each client gets their own branded portal. They can log in, view their campaign metrics, watch their email reputation build over time, and engage with their outreach, all without seeing any data that belongs to another client or to AvoraGrowth's internal operations.
"The way you can create client sub-accounts on Smartlead is like no other tool out there. They're super simple, super cheap."
For an agency managing 20-plus clients, this is not a minor convenience. It is what makes a professional, scalable service model possible.
Reply handling is one of the most time-consuming parts of cold email agency work. When a lead responds, someone needs to craft a thoughtful follow-up quickly. At scale, that becomes a drain on the team and a source of delays that cost conversions.
SmartAgents changed the economics of that problem for AvoraGrowth. An AI agent trained on each client's context generates a draft reply. The client reviews it, adjusts if needed, and sends it in a fraction of the time it would take to write from scratch.
"It's just nice to see when you have an AI agent make a super nice email, especially when you've trained it correctly. Saves a lot of time and saves you from thinking, what should I say? You just look at the preview, change it a little to your liking, and send it off."
AvoraGrowth holds structured performance reviews across client campaigns. Reply rates, positive reply rates, copy performance, lead quality: all of it gets reviewed and acted on.
Smartlead's dashboard makes that process straightforward. Metrics are clear, exports are available, and the layout supports the kind of weekly review rhythm that keeps campaigns improving over time.
"It makes it super easy with Smartlead's platform, just looking at the reply rates, the positive reply rates, and everything in between."
As client campaigns grow, lead storage limits become a hidden operational cost. Agencies either pay more to expand capacity or spend time cleaning out old data to stay within limits. Neither is a good use of resources.
The removal of that constraint gave AvoraGrowth more flexibility to scale without managing an artificial ceiling on data volume.
"You can upload as many contacts as you want and it's unlimited and you don't have to pay more. That's probably the best thing you guys have added to Smartlead recently."
1. SmartAgents. AI reply drafting that reduces time spent on reply management and keeps response quality high across every active campaign.
2. UI and dashboard. Clean metrics display, downloadable exports, and a layout that makes structured performance reviews fast and actionable.
3. Warm-up pools. The most reliable warm-up infrastructure Alexander has tested across all tools, maintaining deliverability at scale across all client accounts.
4. API and webhooks. A well-documented, flexible API that powers AvoraGrowth's entire automation stack, including the GoHighLevel integration that eliminated manual lead routing.
5. Client sub-accounts. Simple, affordable, and built for agencies. Each client gets a separate, branded workspace without any complexity overhead.
AvoraGrowth is expanding.
The foundation is already in place: a proven outbound system, strong client results, and an operating model built around Smartlead that supports both scale and efficiency. Alexander is focused on continuing to grow the client base while keeping the quality of results high.
The one improvement on his wishlist is a mobile app for client access. Outside of that, he sees the platform as a strong fit for the way AvoraGrowth operates today and where it is heading.
"Everything at the moment that you have in Smartlead is amazing. There's nothing really that needs to be changed specifically for our use case."
