What Smartlead offers that
Klenty doesn't

Unlimited email accounts

Connect as many mailboxes and domains as you need on every plan. Klenty caps mailboxes per user, so growing your sending volume means buying more seats.

2,000 free verified leads/month

Included via SmartProspect on the starting plan. On Klenty you reach bundled data credits only on the Plus tier at $99 per user a month.

Ultra-premium warmup pools

View pool quality, audit reputation, and upgrade tiers. Klenty lacks transparent pool tiers.

SmartAgents

AI agents that route hot leads, update your CRM, and trigger next steps across channels based on real behavior. No rigid cadence steps.

Calling with full email context

SmartDialer runs as a step in the same sequence as your emails, so reps see every message already sent before they dial. Calls are recorded, transcribed and summarised straight onto the lead timeline.

Why outbound teams prefer
Smartlead over Klenty?

Unlimited accounts — no mailbox caps, no extra seats

Klenty caps mailboxes per user, so adding sending volume means adding seats, and seats run $70 per user on Growth and $99 on Plus. Smartlead lets you connect unlimited email accounts and domains on every plan starting at $39 a month. Load-balance your sending volume across 10, 50 or 100 inboxes without paying extra.

Ultra-premium warmup pools you can see

Klenty includes deliverability tools but doesn't show you warmup pool quality or who you're warming alongside. Smartlead shows your exact Warmup Pool Tier and Global Warmup Score, with a clear upgrade path to Ultra-Premium Pools reserved for high-reputation senders. Better inbox placement means more opens, more replies, more booked meetings.

Calling runs inside your email sequence

On Klenty, calling takes a tier you upgrade and parallel dialing is a separate $45 per user add-on on top of that. On Smartlead, SmartDialer works a step in the sequence your emails already run in. A rep opens the queue, sees the full email history for that lead, dials, logs a disposition, and the sequence picks up from there. The call, the recording and the transcript land on the same timeline as the emails, so nothing needs syncing between a calling tool and a sending tool.

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.

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

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.

Gabriel Martinez

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.

Maximilian Jendrall

CEO, Halfwarm

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.

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.

Frequently asked questions

Does Smartlead really offer unlimited email accounts?

Yes. Connect as many sender accounts (Gmail, Outlook, SMTP) and domains as you need on every plan. Smartlead's deliverability approach relies on load-balancing volume across multiple accounts, so there's no reason to cap them.

Can I manage multiple clients on Smartlead?

Yes. Smartlead's whitelabel feature lets you give each client a branded view of their campaign performance. Unlimited team seats means your entire agency team works from one account. With Klenty's per-user pricing on Growth and Plus, each additional team member increases your bill.

How does Smartlead handle multichannel outreach compared to Klenty?

Klenty opens calling and SMS on its Growth plan at $70 per user a month, with 200 minutes included. Smartlead runs email and LinkedIn on every plan and adds SmartDialer from the Unlimited Smart plan, with SmartAgents triggering the next step based on how a lead actually behaves rather than a fixed cadence.

Is Smartlead cheaper than Klenty?

Klenty's Starter plan is $50 a month for email only. Once a team needs calling it moves to Growth at $70 per user, so five reps cost $350 a month before the $45 per user parallel dialer add-on. Smartlead's Unlimited Smart plan is $174 a month flat with unlimited seats, and voice credits start at $9 a month.
