Company Overview

Surgemail.ai, co-founded by Clayton Goldman, is a cold email infrastructure platform built by cold emailers, for cold emailers. surgemail.ai gives teams tools to scale their outreach while ensuring optimal deliverability and safety when sending emails. 

Their platform offers US-hosted Google Workspace inboxes for under $1 per month, optimized for high deliverability, clean sending, and safe scale. surgemail.ai serves clients across various industries, focusing on helping agencies and businesses scale their cold email outreach without falling into spam folders.

Clayton and his team at SurgeMail have been in the cold emailing business for over two years, providing both cold email services and white-labeled infrastructure for their clients. 

Surgemail has successfully generated multiple six-figure commissions and profits for their clients.

The Challenge

Before integrating Smartlead into their operations, surgemail.ai faced several challenges, primarily in email deliverability and response rates. These issues included:

Email Deliverability

Struggling to get their cold emails into recipients' primary inboxes.

Low Response Rates

Despite having well-targeted lead lists, they faced difficulty in generating meaningful replies from prospects.

Inefficient Campaign Management

Managing multiple client accounts and responses became cumbersome without proper tools for tracking and automation.

Clayton explains, "We faced huge hurdles with deliverability and response rates. We could not scale effectively until we found a solution that would help us manage multiple accounts and improve our response rates."

Why Smartlead?

After experimenting with various cold emailing platforms, surgemail.ai chose Smartlead for its comprehensive feature set and high-level automation capabilities. The platform’s ease of use and ability to monitor inbox health, automate workflows, and improve deliverability made it the perfect fit for their needs.

Key Features That Helped surgemail.ai Succeed

1. Warm-Up and Deliverability Tools

One of the standout features of Smartlead for surgemail.ai was its warm-up functionality. Before using Smartlead, managing inbox health and ensuring emails landed in the primary inbox was a major pain point. 

With Smartlead’s warm-up feature, surgemail.ai was able to increase deliverability and avoid spam filters effectively. 

Clayton says, "The warm-up feature has been a game-changer for us. It significantly boosted our deliverability rates and allowed us to land in the right inboxes."

2. White-Labeling Capabilities

surgemail.ai provides white-labeled cold email infrastructure to its clients. Smartlead’s white-labeling features allowed them to brand the tool as their own, making it easier to scale and manage multiple client accounts without compromising on quality or transparency. 

This ability to seamlessly integrate and provide a tailored experience to their clients was key in building long-lasting partnerships.

3. API Integrations

Smartlead's API access was another essential feature for surgemail.ai. By using the API, surgemail.ai could integrate Smartlead with their existing tools, including Slack for response management. 

This integration helped them automate and streamline the process, saving valuable time.

"The API is fantastic. It allows us to connect Smartlead with our systems and streamline operations, reducing manual work and increasing our efficiency."

4. Spintax and SmartDelivery

Spintax and SmartDelivery were pivotal in surgemail.ai’s success. Smartlead’s spintax feature helped them scale outreach without risking email duplication, and SmartDelivery ensured that their emails were always delivered to the inbox, not the spam folder. 

The spintax feature allows them to personalize emails at scale without relying on generic templates. It also helps in maintaining a high level of deliverability across multiple domains and inboxes.

Results Achieved

By leveraging Smartlead’s powerful features, surgemail.ai saw remarkable results in terms of both engagement and revenue. Their campaigns produced impressive response rates and generated significant revenue.

  • 17% Response Rate: One of their most successful campaigns resulted in a 17% response rate with a 38.78% positive reply rate.
  • 83.83% Positive Reply Rate: Another campaign achieved a response rate of 17.75% with an outstanding 83.83% positive reply rate.
  • $70K+ in ARR: Clayton shared their success of generating over $70K in annual recurring revenue (ARR) in just one month from a single cold email campaign, showcasing the massive potential of Smartlead in driving revenue.
  • Six-Figure Deals: surgemail.ai also secured several six-figure deals for their clients, thanks to improved deliverability, optimized targeting, and efficient email management through Smartlead.

The Secret Sauce to surgemail.ai’s Success

Clayton and his team attribute their success to a few critical factors that work hand-in-hand with Smartlead’s capabilities:

Targeted Leads

Most cold emails fail because of bad lists. Their leads are always well-targeted, relevant, and highly qualified.

Compelling Offers

surgemail.ai focuses on high-value offers that address the prospect’s pain points. "If your offer doesn’t immediately feel worth replying to, nothing else matters."

Sharp, Direct Copy

Their short, clear, and concise emails ensure they grab attention without unnecessary fluff.

Minimal Personalization

surgemail.ai relies on effective targeting and spintax to keep emails unique and relevant. "We don’t use personal hooks. If your message needs a personal touch to land, it’s probably not strong enough."

Sending Accounts

They use their own tech stack – Surgemail.ai – and follow this framework: Clean infra + smart sending = scale without issues.

Client Testimonials and Feedback

Clayton also emphasized the excellent support provided by Smartlead. 

“The customer support is stellar. The response time is extremely fast even when we need assistance with something minor. The Slack community is another great resource for sharing insights with industry peers."

Final Thoughts

Smartlead has been instrumental in transforming surgemail.ai’s cold emailing processes, from boosting deliverability to automating tasks and managing client campaigns effectively. With more than a hundred thousand cold emails sent and millions in revenue generated, surgemail.ai has become a success story of how leveraging the right tools can significantly scale a business.

“Smartlead has changed the way we do cold emailing. It covers all our needs, and we’ve seen results that we wouldn’t have achieved with any other platform.” – Clayton Goldman, Co-Founder, surgemail.ai

Bharatt Arorah

Deliverability is the cornerstone of cold email outreach. You could have the best email copy in the world, but if no one is seeing it, it's useless. I really love the feature where you can actually give client accesses to your clients.

Wesley Hoang

Co-Founder, Cymate

I do not want to switch to another software. Pick a solution you trust, stick with it, and keep refining your copy.

Bruno Erckmam

CMO, Avalanche Capital

Managing large volumes of emails through multiple inboxes used to be a logistical nightmare. With Smartlead, the process is seamless. We book thousands of discovery calls through cold emails. These campaigns are generating leads at a scale we never thought possible.

We came for the unlimited inboxes, and we stayed for the API. 1.5M cold emails/month, 7,767+ inboxes managed.

Our approach to crafting conversational emails led to reply rates that many of my peers thought were unattainable.

Maximilien Moriceau

Co-Founder, letstrike

We've grown on zero capital, zero marketing, purely cold emailing - and that's the story we love to tell. The best approach is no approach if you can't handle domain meltdown. The second best is something like Smartlead that's built from the ground up for deliverability at scale.

Omar Abdalla

Founder, Fenixtal

Smartlead's white-labeling and automation let us punch above our weight. The 12M euros sales potential? That's what happens when you combine human creativity with Smartlead's precision.

Nine out of 10. Ninety percent of our clients are on Smartlead unless they come in with an existing setup. That's the default.

Ethan Chamish

Co-Founder, BuildingReach

At the end of the day, you have to take a bet on one tool or another. It was a no-brainer taking that bet on Smartlead. We had to even turn down the volume of our marketing campaigns - Smartlead was capable of driving more volume than our sales team was able to fulfill.

There's so much stuff built on top of it. I would be dead if I had to rebuild it with another tool. I can manage hundreds of senders easily. I can send hundreds of thousands of emails.
