AvoraGrowth is a B2B growth partner specialising in cold email outreach for local service businesses in the US. Founded by Alexander Yevtushenko.
Alexander Yevtushenko didn't come from a cold email background.
He came from web design.
But when he saw what cold email could do, he pivoted hard and built AvoraGrowth into a B2B growth partner generating multi-million dollar pipelines for local service businesses across the US.
In Q3 and Q4 of 2025, AvoraGrowth generated over $2 million in pipeline for their clients. They are now pacing to hit $4 million. They have over 20 active clients. And 90% of those clients run on Smartlead.
This is how they did it.
How It All Started: From Web Design to Cold Email Dominance
Alexander didn't plan to build a cold email agency.
Three years ago, he was running a web design operation, websites as a service, clean and simple.
But the more he watched people in his network crush it with cold email, the more he realised where the real opportunity was.
The math was undeniable.
Cold email scales in a way cold calling simply cannot. You can reach 1,000 people in a day with messaging that feels personal. You can double your send volume by doubling your inboxes.
You can automate follow-ups, personalise at scale, and track every metric that matters. Cold calling cannot do that. SMS cannot do that. Cold email can.
So Alexander made the switch.
He took the skills he had built getting his web design agency to $20,000 to $30,000 per month and redirected them entirely into outbound for local service businesses. Painting companies. Commercial cleaning. HVAC.
The kinds of businesses that have real revenue potential but rarely get the kind of sophisticated outbound infrastructure that SaaS companies take for granted.
That gap is exactly where AvoraGrowth lives.
Key Challenges Faced Along the Way
Scaling Without Sacrificing Deliverability
Local service businesses are a different beast. Apollo databases do not have the data.
LinkedIn scrapes do not apply. For AvoraGrowth's clients, Google Maps data is fresher and more relevant than any traditional B2B database. But scraping that data and turning it into campaigns at scale, across 20+ active clients, requires infrastructure that does not fall apart under volume.
The big risk with high-volume outbound is always the same. You scale up, deliverability tanks, and emails start hitting spam. For an agency whose entire value proposition is booked calls and pipeline, that is an existential problem.
Training Clients Without Slowing Down
AvoraGrowth does not just run campaigns in a black box.
Their clients are involved.
They need to see metrics, understand what is working, and respond to interested leads quickly.
That means the platform has to be simple enough for a painting company owner to navigate, not just a sophisticated agency operator.
Keeping Operations Lean Across 20+ Clients
At 20 active clients, every manual step is multiplied by 20. Uploading campaigns, routing interested leads to clients, managing inbox replies, tracking metrics across accounts. If any of those steps requires manual effort, it becomes a bottleneck fast.
How Smartlead Helped Solve the Challenges
Warm-Up Pools That Actually Work
Alexander is direct about this: Smartlead's warm-up pools are the best he has tested. Not just better than some tools, but better than all of them.
For an agency sending high volumes across dozens of client inboxes, the warm-up period is critical.
The first two to three weeks determine whether a domain 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 they needed to send at scale without ending up in spam.
API-Powered Automation That Eliminates Manual Work
This is where AvoraGrowth's operations get serious.
They connected Smartlead directly to Go High Level via Smartlead's API, building an automation where every interested lead gets instantly pushed to the client's pipeline as a new opportunity, complete with all the lead information they need to book a call, schedule an estimate, or send a quote.
No copy-pasting. No manual routing. No leads falling through the cracks. The moment a lead shows interest, the client gets notified and the follow-up process starts automatically.
"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."
Client Sub-Accounts That Make White-Labelling Simple
At $29 to $30 per client, Smartlead's sub-account model is the most cost-effective white-label setup Alexander has found. Each client gets their own branded backend portal. They can log in, see their own metrics, and engage with their campaigns without seeing anything that belongs to another client or to AvoraGrowth's own operations.
"The way you can create client sub-accounts on Smartlead is like no other tool out there. They're super simple, super cheap."
SmartAgents for Seamless Reply Management
One of the biggest time drains in cold email agency work is reply handling. When a lead responds, someone has to craft a follow-up fast. SmartAgents changed that for AvoraGrowth's clients. An AI agent trained on the client's context generates a reply, and the client either approves it with one click or tweaks it slightly before sending.
"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."
A Dashboard Built for Weekly Reviews
Every Monday, AvoraGrowth holds a team meeting to review every client's campaign metrics. Reply rates, positive reply rates, copy performance, lead quality. Everything gets reviewed and tweaked. Smartlead's dashboard makes that review fast and actionable, with downloadable metric exports that make building client case studies straightforward.
"It makes it super easy with Smartlead's platform, just looking at the reply rates, the positive reply rates, and everything in between."
Unlimited Lead Storage
One of the more recent additions that Alexander flagged as genuinely game-changing: unlimited lead storage. Previously, agencies had to pay extra, sometimes $50 to $100 more, every time they needed to scale their lead database, or constantly delete old leads to stay within limits. That constraint is gone.
"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."
Notable Achievements
- $2M+ in pipeline generated for clients in Q3 and Q4 of 2025
- Pacing to hit $4M in pipeline for clients in the following period
- 20+ active clients, 90% running on Smartlead
- 10% reply rate and 30% positive reply rate on a recent painting company campaign, against an industry baseline of 4 to 5% reply rate and 10 to 20% positive reply rate
- Fully automated lead routing from Smartlead to Go High Level with zero manual intervention
"A campaign we recently launched for a painting client, a company doing around $1M per year, we've been getting a 10% reply rate and 30% positive reply rate. That's a super good metric."

Vision for the Future
AvoraGrowth is expanding.
Alexander is eyeing new markets beyond local service businesses, though he is keeping those plans close to his chest until he is ready to move.
The foundation is already there. A proven outbound system, a reliable tech stack built around Smartlead, and a growing track record of pipeline results that speak for themselves.
The one thing on his wishlist: a mobile app for client access. It is in development, and it is the only improvement Alexander flagged in the entire conversation.
