Review Smartlead on G2
Felix Frank

Founder, StackOptimise

Smartlead's combination of automation, unlimited inboxes, and easy campaign management has completely transformed how we run cold email campaigns.

Justin Chi

Founder, Cold Email Hackers

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

Sander Poolman

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.

Brigitta Ruha

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.

Daniel Greaves

Founder, FueltoFly

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

Harris Kenny

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.

Sergio Ocampo

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.

Bharatt Arorah

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.

Siddharth MV

Founder, Phyros

I'm amazed at the response time of Smartlead's customer support.

Louis Deslus

Head of Growth, EraB2B

I didn't want a tool built by a marketing team with flashy features that didn't solve real problems. I wanted a platform built by experts in email deliverability, and Smartlead checked all the boxes. Smartlead isn't just a tool for us, it's a part of our infrastructure.

Isaac Wood

Founder, Lever Growth

We focus on having consistent email deliverability for us and our clients, and Smartlead has consistently helped us achieve that.

Emmanuel Akatobi

Founder, PLNITUDE

Client Access and white-labeling have been a game-changer, saving us countless hours. With Smartlead, I'm happy with everything, but then I check their Slack community, and there's a new feature that just dropped!

Sebastian Grinkraut

CEO, Agile B2B Sales

SmartDelivery and SmartServers have been instrumental in helping us navigate the ever-changing deliverability landscape. The platform's ability to adapt to deliverability changes and provide real-time insights has been critical to our success.

Stan Stojanovic

Founder, frontBrick

Outbound isn't dead; it's just that the bar is higher now. Smartlead allowed me to unify advanced deliverability with multi-channel sequences, and that was a game-changer.

Alexis Lacabane

CEO, OneThousandPieces

From the beginning, Smartlead enabled us to build client access. Everything has been driven around making people like us revenue. I've seen the evolution of the tool, and it perfectly aligns with how I evolved myself in my business.

Abbas Somji

Co-Founder, The Playbook Agency

If you're a founder or a Sales VP looking to book meetings at scale with automation, Smartlead is your best bet.

Founder, Leadgrove.io

Using Smartlead's APIs has been a huge, huge game changer in our business. If you're an agency serious about scaling and signing new clients, Smartlead is the reliable partner you need.

Christian Oland

Founder, RevGen Labs

The accessible API was the number one feature that allowed us to build RevReply and automate everything - from response handling to custom reporting.

Rish G.

Founder, Cleverviral

We needed more agency-focused support, and since then, we haven't looked back.

Marc Gasser

Founder, Cotide

We integrated Smartlead for the whole sending part... we have a complete view.

Sebastian Vinther

Co-Founder, The Growth DNA

The decision to incorporate Smartlead was a no-brainer. Smartlead has given us the speed and flexibility to meet our clients' demands quickly.

Jaime de Wenetz

Founder, Unlock Management

50% of the business is made in Smartlead. Everyone that's doing outbound is using Smartlead. Emails don't go to spam, so why should we change it? In just 30 seconds, you can do everything. Being so simple and so effective at the same time, I think it's really important.

Aaron Ensminger

Founder, Brokr Leads

The ability to manage multiple email accounts, track every lead, and enjoy high reply rates through Smartlead has fundamentally changed our business.

Romain Osman

Co-Founder, Five Element

Smartlead is an absolute game-changer! With its exceptional features and support, I've experienced remarkable success. I would rate it 10 out of 10 for satisfaction. Smartlead enabled us to save valuable time and resources, leading to increased revenue and improved profitability.

Phil Sergenti

Founder, First LLC

The best one is actually real sending data - you have real hard data, which is, this actually bounced for three other users. The product is solid. I don't feel like I need that many features because the basics are covered.

David Borman

VP of Operations, KeyOutreach

Intuitive. Game-Changing. POWERFUL. Analytics, spintax, A/B testing, quick personalization. This is a game changer.

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.

Eric Nowoslawski

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.

Ari Sohn

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.

Atishay Jain

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.

Matteo Fois

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.

Piotr Mikrut

Founder, Experiment5m

Smartlead's automation and deliverability features transformed how we run outbound campaigns. This platform has been a game changer for our agency.

Jed Mahrle

Founder, Practical Prospecting

Every cold email tool can automate a sequence, but Smartlead focuses on what truly matters: deliverability and simplicity. Since I started using Smartlead, they seem to come out with new features every month. I've never reached that number in another tool. (referring to 500+ meetings)

Ryane Tully

Co-Founder, Pitchlane

With Smartlead, Pitchlane's B2B outreach has taken a significant leap forward. Our response rate skyrocketed to 16%. On a scale of 1 to 10, I would give it a solid 100.

Ryan Redmond

Founder, Cold Outreach Systems

Smartlead has helped us break records month after month for booking meetings and managing inboxes. It's super easy to scale without losing quality. We tried other tools, but they were clunky and hard for clients and our team. Smartlead's intuitive design made it the obvious choice.

Thijs van der Veer

Founder, Leadodo

Smartlead syncs effortlessly with Leadodo's lead database, making the job much easier for us. Smartlead's support team works 24/7 to help you with any issue, which is a welcome change from other support services.

Hugo Millington-Drake

Co-Founder & COO, Trigify

When we started our agency, we started with Smartlead on cold email, and we got that from zero to 30,000 a month in six months.

Johannes Fessler

CEO, Rock Solid Lead Generation

Smartlead is absolutely amazing! The software is easy to understand. I am not a techie but directly understand everything and if you really have a question the team always helps instantly.

Ty Shane

Founder, 10x AI Advisors

SmartDelivery has been the 100% reason we were able to achieve the numbers for our campaigns. Smartlead is the foundation of our cold email success. If Smartlead evolves into agentic AI integration, it will redefine the future of outbound.

Vladislav Molchanov

CEO, The Pipeline Inc.

Smartlead improved our deliverability and gave us the tools to turn cold emails into conversations. The support team's expertise was the cherry on top.

Mohan Muthoo

Founder, Spring Drive

My agency, for all of our clients as well as for our own campaigns, relies on Smartlead. It has truly become a cornerstone of our growth. Our reply rates are approximately 500% higher compared to those we experienced with legacy tools.

Frederik Jakobsen

Co-Founder & CEO, Danish Lead Co.

We run our entire business on your platform. We're sending plus 500,000 emails a month right now. The fact that we're able to do that and still primarily land in the inbox, all of that wouldn't have been possible without Smartlead.

Taylor Haren

Founder, Sales Automation Systems

AI will beat me at every level, so I learned how to use it instead of competing against it. 130% company growth in one year, 62% positive reply rate, $8.19M in staffing sales.

Calvin Wiltermood

Advisor, Trailway Growth

Smartlead, without a doubt, in my opinion, is the best tool in the market for cold email outreach. We're barely scratching the surface of what's possible. It's a foundation for agency growth. $700K+ ARR closed, 33% positive reply rate on 13,000-prospect campaign.

Tim Yakubson

Founder, B2B Boosted

We're probably averaging about 140 meetings per month, and most of them are coming from emails.

Jesse Hernandez

CEO, LearnEmail.com & MailGenius

With Smartlead, I was able to generate between 6,000 and 8,000 opt-ins and over 15,000 replies from cold email campaigns. Smartlead has excellent customer support, and Vaibhav is one of the best leaders I've ever seen. 620 replies in a single day with just 178 mailboxes. I scaled up to 8,800 emails a day and 450,000 emails a month.

Charles Moriceau

Co-Founder, letstrike

I started in cold email with a Google Sheet hack. Now we run everything from a single platform that handles hundreds of clients, multiple domains, advanced analytics.

Jayson DeMers

Founder, EmailAnalytics

When we started using it, we were pretty happy with the results and the ease of use. Once we got used to it, there was really not been any reason to move away from it. Smartlead enables us to use custom domains for tracking, which improves deliverability.

Felipe Fuhr

Partner & COO, Done For You Meetings

Smartlead has been a game-changer for us. The API and automation features have allowed us to streamline our processes and scale our campaigns without adding more team members.

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.

Preeti Malik

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.

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.

David Sinclair Black

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.

Philipp Käming

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.

Aamir Bajwa

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'.

Ryan Bryden

Founder, Apex Ascension

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

Noah Gill

Founder, Leadmoves

Since using Smartlead, my clients have added millions in pipeline revenue, closed six-figure deals, and gotten 38 new customers in a single month.

Joao Simoes

Founder, Virtus Medium

Everything under one roof: I can see campaigns, leads, and domain status without leaving the platform. Warm-up that I can forget about: The system ramps send volume on its own, which frees my time.

Rene-Karl Lambert

Founder & CEO, Wind Growth

If you're a big automation enthusiast like me, there are no other tools on the market that allow you to 100% automate your business as Smartlead does. Smartlead easily saves me about 40 hours per week.

Alexander Yevtushenko

Founder, AvoraGrowth

The way you can create client sub-accounts on Smartlead is like no other tool out there. They're super simple, super cheap. 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.

Patrick Spychalski

Co-Founder, The Kiln

I think people who are at the forefront of the correct tech tools like Smartlead and Clay are going to be the runaway leaders. We've had several clients that we've generated millions of dollars for, just using Smartlead campaigns.

Papa A. Sefa

Founder, Leveraged Outbound

My entire business is pretty much built upon Smartlead. Without it, I wouldn't have any business. Smartlead helped us save 80% of our time, book 20-30 monthly meetings, and close six-figure deals for our clients.

Wyatt Beemer

Founder & CEO, Soteria Media

The APIs and automations you can do with Smartlead are out of this world and it helps me run my business very smoothly.

Jack Hayward

Founder, FinestGC

Using Smartlead has been a total game-changer and has been one of the primary drivers in our ability to generate over $12M in the pipeline for our clients last year. The Master Inbox alone has saved us a considerable amount of time, the custom tagging system and subsequences save us at least 2 hours a day.

Julia C.

Account Executive

I like how easy it is to launch a campaign with Smartlead and how effective it is at delivering emails. It allows me to use multiple inboxes that it creates to safely send emails in bulk. The initial setup was very easy, and this contributes to the overall user-friendliness of Smartlead.

Preeti M.

Co-Founder, Digital Creativs

The platform and features continue to be updated and improved. Strong founder who cares about what users want to see and an amazing support team. The office hours on various topics such as email deliverability with the experts is nothing like I've seen for other SaaS products and the Smartlead Slack community is a cherry on top.

Bojan B.

Member, Lambda Group

I love the community and their Slack channel. I'm also thrilled with the AI inbox manager after the latest update because it saves us a lot of time, eliminating the need for VAs to manage inbox tasks. The setup was quite easy and they provide really extensive documentation and a very helpful community.

Atishay J.

Founder, Hyperke

I really appreciate the amazing customer support from Smartlead. Nobody even comes close in comparison. The founder Vaibhav is super helpful and hands-on with everything. The tool itself is reliable and technically sound. Plus, their APIs work well, which is another big plus for me.

Orestas N.

VP of Accounts, A-SALES

A comprehensive email outreach platform that converts cold emails into consistent qualified sales meetings for us, and our clients. It helps scale outreach with unlimited mailboxes, unlimited warmups, a limitless multi-channel infrastructure, and a unified inbox so we can manage our entire revenue cycle in one place.

Charlie M.

Chief Executive Officer, Infoxify

It is a seasoned/advanced tool to send cold emails to your prospects. Many great features are there to improve the deliverability. Customer support is very nice, though it may take a while for you to get answer (It's not prompt response unless you are on their higher tier plan).

Emmanuel A.

Founder, PLNITUDE

Game changing tool for my agency, helping us generate 6-figures+ for our lead generation clients! Client Access and white-labeling have been a game-changer, saving us countless hours.

Associate Manager - Marketing

I use Smartlead for cold outreach, and it really simplifies things for me. I love how it handles the email warming up automatically and delivers emails without harming my domains.

Frequently asked questions

What is SmartSenders and what does it do? 
+

SmartSenders is Smartlead's built-in email infrastructure setup feature that lets you purchase domains and mailboxes directly inside the platform. Instead of dealing with multiple providers and manual configurations, you select your domain, choose Google, Outlook, or SMTP mailboxes, and SmartSenders handles the entire setup automatically. All DNS records including SPF, DKIM, and DMARC are configured for you.

Which email providers does SmartSenders support?
+

SmartSenders currently supports Google, Outlook, and SMTP mailboxes. You can purchase these mailboxes from trusted providers like Zapmail, InfraInbox and Mailreef. Each provider comes pre-configured with authentication records and deliverability best practices. Smartlead has indicated plans to include more email service providers in the future.

Do I need technical knowledge to set up mailboxes through SmartSenders?
+

No technical knowledge is required. SmartSenders handles the entire infrastructure setup including DNS configuration, mailbox creation, and authentication record setup automatically. MX, SPF, DKIM, and DMARC records are all configured for you.

How long does it take for mailboxes to be ready after purchase?
+

Mailboxes purchased through SmartSenders are activated within 24 to 48 hours. This window is required for DNS record propagation to complete properly across all email providers. Once activated, mailboxes are connected directly to your Smartlead account and ready for warmup and campaign use.

Why should I buy mailboxes through SmartSenders instead of individual vendors?
+

SmartSenders provides access to pre-vetted vendors and ensures that all technical configurations are handled automatically. It also offers optimized infrastructure for deliverability and removes the need to manage multiple providers separately. Additionally, mailboxes are often available at more competitive pricing compared to traditional resellers.

Do SmartSenders mailboxes still need to be warmed up? 
+

Yes, standard mailboxes purchased through SmartSenders are new inboxes with no prior sender history, so warmup is required before running campaigns. However, SmartSenders also offers pre-warmed mailboxes through Zapmail that have already completed the warmup process and are ready to send from on the same day, bypassing the typical 2 to 3 week warmup period.

 How does SmartSenders help with email deliverability?
+

SmartSenders improves deliverability in several ways. Domains come with correctly configured authentication records, high-quality US IPs, and DNS management. Each domain operates in its own isolated workspace, so a reputation issue on one domain does not affect others. You can also diversify sending across Google, Outlook, and SMTP providers within the same campaigns to avoid single-provider dependency and reduce spam triggers.

How does SmartSenders handle DNS setup for purchased domains?
+

All DNS records including SPF, DKIM, DMARC, and CNAME records for custom domain tracking are configured automatically when you purchase a domain through SmartSenders. There is no manual input required from the user. This ensures your domains are correctly authenticated from day one and reduces the risk of emails landing in spam due to misconfigured records.
