Key Highlights

  • 20% average reply rate across campaigns.
  • 50% conversion rate from replies to closed deals.
  • $10M+ revenue generated for 150+ clients over 7 years.
  • 68.53% positive reply rate from 5,311 sent emails.

Client Overview

Oleksandr Ivanets, CEO of Before Hello, leads a team of email deliverability experts trusted by global enterprises to turn cold emails into revenue drivers. Since 2017, Before Hello has:

  • Specialized in outbound B2B campaigns that are focused on industries like SaaS, fintech, and healthcare.
  • Prioritized quality over quantity and rejected “spray-and-pray” tactics, opting for hyper-targeted, high-value outreach.
  • Built a reputation for inbox mastery by navigating Gmail, Microsoft, and regional ISP filters to ensure emails land and convert.

Challenges Before Smartlead

Despite their expertise, Before Hello faced hurdles in a shifting email landscape:

Algorithm Wars

Google and Microsoft’s frequent security updates tanked email deliverability for outdated tools.

Content Fatigue

Prospects ignored generic sales pitches, demanding “irresistible” value upfront.

White-Label Costs

Building custom client dashboards in-house was prohibitively expensive.

Tool Fragmentation

Existing platforms lacked end-to-end features for scaling personalized campaigns.

“Most cold emails fail because they’re transactional, not conversational. Our campaigns work when we spark dialogue—but that requires tools that don’t treat emails as spam.”

Why Did Oleksandr Choose Smartlead?

After testing every tool in the market, Before Hello chose Smartlead for its:

Unmatched Deliverability

AI email warmups, spintax options, dynamic ESP matching, and SmartDelivery ensured 95%+ inbox placement.

White-Label Client Portals

Saved thousands of dollars in dev costs with ready-to-use dashboards with Smartlead’s white labeling.

Continuous Innovation

Constant updates (e.g., new spam filters and new features like SmartServers and SmartSenders) kept campaigns ahead of algorithms.

Community-Driven Support

Slack group and webinars provided real-world strategies, not just ticket replies.

Solutions & Features That Made the Difference

1. White-Label Transparency

  • Clients access real-time campaign data (opens, replies, spam rates) via branded dashboards.

2. AI-Optimized Deliverability

  • Rotated IPs/domains to mimic human sending patterns.
  • Pre-send checks flagged risky phrases (e.g., “free trial,” “discount”).

3. “Conversation-First” Campaign Framework

  • Irresistible Offers: Replaced sales pitches with consultative hooks:
    • “We helped [Competitor] reduce churn by 30%—can I share how?”
  • Behavior-Triggered Sequences: Paused emails after prospects replied to avoid overselling.

4. Global Community & Education

  • Smartlead’s Slack group helps us to share and learn deliverability hacks with 5k+ cold email experts.
  • Smartlead’s weekly webinars on topics on email deliverability, cold email outreach tips, and others help us immensely in our cold email strategy.

Key Results Achieved

  • Our campaigns have an average 20% reply rate regardless of the emails sent.
  • 50% conversion rate from replies to closed deals.
  • We have helped 150+ companies generate $10M+ in revenue over 7 years.
  • One of our campaigns, which had 5,311 emails sent, generated a 68.53% positive reply rate.
“Smartlead isn’t just a tool—it’s a partnership. The white-label dashboards makes us look like tech giants to clients.

Looking Ahead

Smartlead has been releasing new features every few months, and we’re looking forward to seeing more from them. Mainly a feature centered around selecting and deleting multiple leads from campaigns.

Conclusion

By combining Before Hello’s deliverability mastery with Smartlead’s enterprise-grade infrastructure, Oleksandr transformed cold email from a gamble into a predictable revenue channel. Their 20% reply rate proves that prospects listen when you prioritize conversations over conversions.


Tools don’t start conversations—people do. But Smartlead gives those conversations the spotlight they deserve. If you want a similar spotlight for your cold email outreach, it’s time you switch to Smartlead.
