In the fast-paced world of B2B tech, demand generation is a key strategy for scaling businesses and driving revenue. However, many companies struggle to achieve consistent results with the challenges of finding the right messaging, scaling outbound systems, and optimizing email deliverability.Â
This was the case for Phyros, a demand generation agency specializing in AI-driven, intent-based outbound systems. Led by founder Siddharth, Phyros helps B2B tech companies in the US and internationally drive revenue through smart GTM strategies, AI-powered systems, and cold email campaigns.
Before discovering Smartlead, Phyros faced the typical struggles of cold email campaigns—poor deliverability, lack of visibility into inbox placement, and low response rates.Â
However, after adopting Smartlead, Phyros overcame these challenges and scaled their and clients' businesses to new heights. Here's a closer look at how Smartlead transformed Phyros’ approach to cold emailing and demand generation.
Phyros is a demand generation agency that helps B2B tech companies—specifically service and product-based software companies—drive growth with highly targeted outbound strategies.Â
They cater to large and smaller enterprises in the early stages of finding their product-market fit (PMF). Phyros’ approach leverages AI-driven systems and data-driven strategies to create scalable outbound systems for their clients, enabling them to reach the right decision-makers and boost revenue.
Despite a strong track record in helping clients build GTM strategies and run AI-powered outbound campaigns, Phyros faced several key challenges in their cold email efforts:
Siddharth discovered Smartlead after watching videos from Levi Arreola, a known advocate for cold email automation tools. After exploring Smartlead through its community and learning about its powerful features, Siddharth decided to switch from Instantly to Smartlead, which paid off quickly.
Powerful API Integration
Master Inbox Feature
Customer Support & Community
The customer support provided by Smartlead, combined with their active Slack community, had been a significant asset for Phyros. Even though they encountered the usual challenges when scaling, Smartlead’s team was always available to help and provide solutions quickly. This ensured that Phyros could focus on growing their business without worrying about technical roadblocks.
I'm amazed at the response time of Smartlead's customer support, especially Vaibhav, who, being the founder and handling many bigger tasks, is always available and active in the Slack community.
Since implementing Smartlead, Phyros has seen impressive improvements in their outreach efforts and those of their clients. The combination of powerful automation tools, better email deliverability, and seamless integrations has allowed them to scale their cold email campaigns to new heights.
Using Smartlead’s SmartDelivery solution and placement tests, Phyros saw a drastic improvement in their email inbox placement rates. By switching to Google inboxes and eliminating poor-performing setups like Outlook, they were able to ensure their emails landed in the right places.
Phyros achieved a remarkable 36.7% unique positive reply rate in just one month for a software client, far exceeding the industry average of 1 positive response per 350 prospects. By improving their email deliverability and using automation, they could scale their outreach efforts and secure meetings with high-value clients.
Phyros generated 36 leads in one month with a 36.7% positive reply rate. This success was made possible by leveraging Smartlead’s advanced features, which enabled them to reach a wider audience and drive more meaningful engagement.
Smartlead played a key role in helping Phyros scale their business to six figures, adding between $10-$15 million in revenue pipeline for their clients by booking meetings with large enterprises such as Amazon, Deloitte, J.B. Hunt, and 20-30 other major businesses.
Siddharth is already looking forward what Smartlead does next after delivery some awesome solutions like SmartDelivery and SmartSenders that changed the deliverability game.
Smartlead has proven to be a critical partner in Phyros’ journey of scaling cold email campaigns and driving revenue for their business and clients. With Smartlead's powerful features like SmartDelivery, API integration, and inbox management, Phyros has optimized its outbound outreach, improved email deliverability, and secured high-quality leads.Â
The results are a 36.7% positive response rate, improved deliverability, and a six-figure business. As Phyros looks to the future, Smartlead remains an essential tool in their demand generation strategy.

Founder, Cold Email Hackers

We have about 15 companies and we use Smartlead for all of them.

Founder, DutchSave Media

One of the things I love about using Smartlead is the deliverability feature. If they landed in the bounce or spam folders, we could resolve this quickly.

Co-Founder, Growth Today

I want to continue to use Smartlead to make operations more seamless - the plan is to bring more clients here and build more SOPs.

Founder, FueltoFly

Smartlead listens to the agencies and customers and builds according to what people want, that has really made things easier for us.

Founder, OutboundSync

We build an infrastructure product, and OutboundSync communicates with Smartlead itself. I love the webhook and API. They're really well done and keep getting better.

Founder, Axoleads

With SmartDelivery, you can put all of that in the hands of the tool. It ensures your emails land in inboxes, and by running a simple test, you can see if you're hitting the mark.

Founder, Claygen
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.

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.

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.

Founder, Growth Engine X

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

Head of Community & Ecosystem, TxtCart

You cannot replace having 10,000 touches with potential clients. When you have that much distribution and reach, you really start to see incredible results. The simplicity of Smartlead made all the difference. It doesn't require you to be a technical wizard.

Founder, Hyperke

Smartlead has been a game-changer for us. It increased our appointment volume, improved ease of use, and offered valuable features. 80% increase in appointments/month, peak of 276 appointments in a single month.

Founder, Kinetyca

Smartlead has been our cold email backbone from day one. The platform evolves constantly, keeping pace with how deliverability and personalization need to work today. 21% overall reply rate, $175K in 4 months for multiple B2B clients.

Founder, Reachflow

Smartlead is centered around deliverability and constantly evolving. Their API is not like any other platform. Smartlead covers all our needs. The focus on core features like deliverability and API integration is unmatched.

CEO, Halfwarm

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

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.

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.

Co-Founder, Digital Creativs

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

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.

Founder & MD, Prospectiv

Since starting the business in January of this year, we've already generated $200K in sales exclusively from cold email. Smartlead has been central to our operations and has exceeded our expectations.

Founder, Growthlynk

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.

Founder, Corebits

The platform's HubSpot integration, real-time Slack updates, and advanced campaign customization have been game changers for our business and our clients'.

Founder, Apex Ascension

From day one, we've never used anything else.
