10 Best Lemlist Alternatives & Competitors [2026]

Lemlist is a sales engagement platform that helps sales teams reach prospects on email, LinkedIn, calls, and WhatsApp from one place.

The tool promises to help you get prospects’ email addresses and phone numbers, build automated multichannel sequences across email, LinkedIn, calls, and WhatsApp, and then land in their inbox with its built-in deliverability booster.

However, some sales teams have been unhappy with the platform for a few reasons, which is why some users have been looking for alternatives on the market.

In this buyer guide, I’ll go over the 10 best alternatives to Lemlist in 2026 that can help you build and refine your best lead list and then orchestrate outreach.

When I was working on the final shortlist, I wasn’t focusing only on feature strength. I also wanted to see the overall customer satisfaction, the use cases of the tools, and their pricing models.

TL;DR

Warmly offers the best alternative to Lemlist with its verified multi-source enriched data (solving Lemlist’s outdated database issues), flexible component-based pricing that eliminates credit burn, and automated audience-building workflows that remove manual list building.
Prospecting tools like Apollo and Cognism are ideal for teams that want large global databases, built-in enrichment, and unified outbound sequencing.
On the other hand, there are tools like MadKudu and 6sense that can help you score, prioritize, and orchestrate your outreach around high-intent accounts rather than building lists manually.

Why have some sales teams been looking to make the switch from Lemlist?

The common reasons why some teams have been looking to switch from Lemlist are its initial learning curve, issues with outdated data, and how easy it is to use up your credits.

But don’t get me wrong here, I’m not trying to claim that Lemlist is a bad tool that you should run from.

In fact, there are many customers who are more than satisfied with its CRM integrations, one centralized inbox, and Lemwarm functionality.

However, there are a few caveats that I found when I tested and researched the sales intelligence solution: ⤵️

#1: Steep learning curve with complex setup

The #1 complaint about Lemlist has been about how difficult it has been for some users to get to know how to use it to its full potential.

Apart from that, other users mentioned that the tool has a complex initial set-up, which further added to their complexity and confusion.

‘’I find Lemlist complicated and difficult to get the hang of initially. It isn't as simple as I would like, which makes it challenging for me to train my intern to use it effectively. The initial setup was also difficult, which adds to the complexity for new users.’’ – G2 Review.

#2: Issues with outdated data

➡️ Next up, some users are not happy with Lemlist’s contact database and mention that there are many entries for businesses that are no longer active.

The lack of accuracy would also mean spending more credits on the wrong prospects and then having your emails bounce.

‘’One aspect that certainly requires more attention is the contact database. Currently, there are too many entries for businesses that are no longer active. I would recommend removing these inactive contacts and verifying the ones that are still in operation. Otherwise, it can be difficult to confirm all the information on your own.’’ – G2 Review.

#3: Running out of credits is too easy

Last but not least, users of the platform mention how easy it is to run out of credits while using Lemlist.

A verified user of the tool mentions that they used about 1,000 credits just to reach just over 100 people across 2 sequences inside the tool.

‘’Overall, I find that credits tend to run out rather quickly. For example, I used about 1000 credits to reach just over 100 people across two sequences. On the Multichannel expert plan, I would appreciate having a higher allocation of call credits.’’ – G2 Review.

#1: Warmly

Warmly offers the best Lemlist alternative in 2026 with our AI Marketing Ops Agent that automatically builds, scores, and continuously syncs high-value, intent-driven audiences across your CRMs, advertising platforms, and outbound tools.

The software removes manual list-building and fragile spreadsheet workflows by continuously discovering, enriching, scoring, and syncing the exact audiences you should be targeting right now.

Disclosure: Even though Warmly is our AI sales software, I’ll provide an unbiased perspective on why Warmly is the best alternative to Lemlist in 2026.

Let’s look at some of the features that make Warmly the go-to option for GTM teams looking to switch from Lemlist:

Automate list building and prospect enrichment with our Marketing Ops Agent

Warmly’s AI Marketing Ops Agent lets you automatically build, enrich, score, and sync dynamic target audiences across CRM, ad platforms, and outbound tools.

Instead of manually exporting lists, cleaning data, or waiting for new leads like you have to do with tools like Lemlist, your team will get an always-fresh, AI-curated list of best-fit accounts and contacts synced across every system.

This is a result of us seeing how sales teams spend a lot of time building, cleaning, and syncing target lists across CRMs, ad platforms, and outbound tools.

In fact, data shows that sales reps spend only ~28–33% of their time on actual selling, and administrative and non-selling work consumes most of their time.

The Marketing Ops Agent automates that, acting as your real-time sales intelligence layer between your data sources and your marketing & sales systems.

Here's how it works:

‎

The Marketing Ops Agent connects directly to your CRM, ad platforms, outbound tools, and intent sources to automate key targeting workflows:

AI-powered lead scoring and enrichment to create dynamic lists ranked by fit and buying intent.
Buying committee identification using insights from past closed-won deals.

Instant audience syncing with HubSpot, Marketo, LinkedIn, Meta, Outreach, and more. No more manual CSV uploads.
Automatic list updates as new intent signals or engagement changes occur.

➡️ This helps our users catch up on in-market prospects doing research, as 96% of prospects research companies before engaging sales, according to research from HubSpot.

Unified buying intent scores that stay synced across every sales and marketing channel.

Find prospects that look just like your best customers

Most sales intelligence tools on the market, like Lemlist, give you firmographic filters, such as industry, headcount, location, and job title, and call it a day.

However, our software goes much deeper.

With our AI-powered ICP identification, Warmly analyzes your actual customer data to uncover what really makes a good fit.

And it’s not just surface-level attributes: it’s patterns across the company tech stack, growth signals, org structure, seniority distribution, and even past engagement behavior.

Once Warmly understands who your best users are, it’ll automatically scan its database of 200M+ contacts to find lookalike prospects, that is, the people and companies that closely resemble your top performers.

The result is a list of not just any prospects, but the right prospects, so your team spends less time guessing and more time engaging the people most likely to convert.

Identify your site visitors at the company and person level

Warmly helps you maximize your site’s lead generation potential by identifying both the companies and individuals visiting it.

All you have to do is add a snippet of Warmly’s code to your site, and the sales intelligence software will start revealing your visitors in minutes.

In addition to company and person-level identification, Warmly will also enrich your visitors’:

Contact data (e.g., email address, phone number, social media profiles, etc.).
Firmographics (e.g., company location, size, funding, etc.).
Demographics (e.g., individual names, job positions, etc.).
Technographics (e.g., tools a prospect uses).

But our visitor identification solution doesn’t stop there.

Warmly also tracks real-time 1st, 2nd, and 3rd-party intent signals to surface the visitors that matter most, so you can instantly prioritize outreach based on actual buying behavior.

That includes:

1st-party signals, such as pricing page views, repeated visits, product usage, or form fills.
2nd-party signals like relevant LinkedIn activity (e.g., industry-relevant discussions, posts, comments, likes, etc.).
3rd-party signals like competitor research or intent keywords being searched.

💡 Data shows that sales intelligence (enriched contact and intent data) can help shorten prospect-research cycles from 3–5 hours to 10–15 minutes, according to a recent industry research, as AI enrichment condenses discovery.

Warmly optimizes its data through a waterfall approach.

Our tool uses multiple data providers (20+), including 2 other leading website de-anonymization providers, to validate the accuracy, quality & overall match rate of our signal & contact data.

We’ve seen that this leads to:

Higher data quantity: Multiple sources expand match rates.
Higher data quality: Proprietary cleansing and confidence scoring validate accuracy.

💡 To maintain data quality and quantity, we continuously monitor vendor performance and validate our proprietary matching algorithms.

➡️ These systems allow us to track quality and quantity metrics in real-time to make sure that both contact-level and company-level data meet the high standards our customers expect.

Warmly’s transparent data commitment means you can test our data quality with our free tier before committing to us as a data provider.

Since our platform aggregates data from 25+ providers and cross-checks it using our proprietary waterfall technique, the software can validate and verify data on your behalf, ensuring it’s of the highest quality.

Turn static prospect lists into automated outreach with AI SDRs

Once you have built the list of leads, Warmly doesn’t just let it sit there. It gets to work for you.

With AI Orchestrator and built-in AI SDR agents, our platform turns every ICP-fit prospect into a warm opportunity by triggering automated, personalized outbound across email and LinkedIn, based on real-time behavior and intent signals.

Here’s how it works:

Prospects who match your ICP and show strong signals (like visiting the pricing page or researching competitors) are instantly added to outbound sequences.
Messages are tailored automatically using contact data, context, and intent.

3. Warmly checks to avoid duplicate outreach and ensures contacts aren’t already being worked.

4. It’s also possible to set rules for account multithreading, so your AI SDR reaches all the key decision-makers, not just one person.

And this isn’t just task automation. It’s real prospecting, at scale, without increasing SDR headcount.

Build targeted lead lists from a 200M+ contact database (Coldly)

Similar to Lemlist, Warmly comes with a built-in prospecting platform, Coldly, which gives your team access to a constantly refreshed database of over 200 million contacts and accounts, so you can build high-quality prospect lists in seconds.

Our prospect database combines powerful filters with real-time enrichment to help you find exactly who you’re looking for across every channel.

Your team will be able to filter by:

Job title, function, or department.
Seniority level and decision-making role.
Company size, revenue, industry, or location.
Tech stack and hiring signals.
And dozens more customizable filters.

➡️ Each lead comes pre-enriched with verified email addresses, phone numbers, and LinkedIn profiles, so your lists are not only accurate but immediately actionable.

Bonus: There’s also a Chrome extension that lets your reps pull contact data directly from LinkedIn or any website, making manual prospecting a whole lot faster.

Warmly’s Integrations

Warmly integrates with a wide range of CRMs and sales platforms, including:

HubSpot CRM.
OpenAI.
Slack.
Apollo.
Outreach.
Demandbase.
RB2B.
Clearbit.
People Data Labs.
And more.

💡 For example, you can combine Warmly’s visitor identification software with HubSpot to alert your sales team the moment a known prospect arrives on the site.

With the HubSpot browser cookie, you can prioritize conversations with the leads who have shown the most engagement with your HubSpot campaigns.

In addition to deep integrations with several lead intelligence platforms, Warmly provides a Warm Bundle: partner discounts for over 25 sales, marketing, and GTM tools.

This way, your team can access many relevant tools and combine them with Warmly at a fraction of their usual price.

Pricing

Warmly’s pricing is modular and component-based and comes with a free plan that lets you identify up to 500 website visitors per month.

You can choose the components that best match the needs of your business, as components are priced by output and not just by a monthly fee.

There are 4 paid product plans that you can choose from:

Signals Agent: Custom pricing, which gives you access to 10,000 monthly credits, Person-Level Intent Signals (1st, 2nd, & 3rd Party), website de-anonymization capabilities, Warm lead alerts, and access to a contact database.
Inbound Agent - Engage: Starts at $20,000/year, and adds AI Chat, native outbound email and LinkedIn automation, intent-powered pop-ups, lead routing with custom CRM fields, and the ability to push leads to sales sequencers.
Inbound Agent - Scale: Starts at $30,000/year, and adds unlimited AI Chat agents, and the ability to push leads to Ad Audiences.
Marketing Ops Agent: Custom pricing, which adds AI-powered account scoring, AI enrichments and custom signals, buying committee identification, real-time buying intent signal tracking, and automatic updates across all enrichments, signals, account and lead lists.

Monthly credits on Warmly are used to track and engage with potential leads.

For example, each interaction or engagement with a lead will use up one credit, such as when you engage with a lead through email or LinkedIn.

➡️ Warmly’s pricing is ideal for larger SMB and MM companies with a growing or mature GTM motion with SDR, sales, and marketing functions.

How is Warmly different from Lemlist?

Lemlist is known for cold email outreach, personalization, and deliverability. The platform helps teams create multistep email sequences, warm up domains, and personalize messages to improve reply rates.

Warmly, on the other hand, goes far beyond traditional email finders and sequence builders by combining visitor identification, intent scoring, automated audience building, and AI-driven activation into one signal-powered revenue orchestration engine.

Our Marketing Ops Agent automatically builds, enriches, scores and syncs dynamic target audiences across your CRM, ad platforms, and outbound tools. Lists are then continuously refreshed as intent signals and engagement change.

Here is a breakdown of the two solutions' functionality:

Pros & Cons

✅ Identify buying committees.

✅ Live sales engagement capabilities.

✅ You can build a real-time, auto-updating list of your best prospects.

#2: Apollo

Best for: Sales teams looking for a unified prospecting and outbound automation solution.

Similar to: Cognism, UserMotion.

Apollo offers a prospect database with built-in sales engagement (sequences, dialling, and email), making it an alternative to Lemlist for teams that want an all-in-one prospecting and outreach stack.

I consider the platform to be especially useful where list generation and multi-touch cadences should live and be measured in the same tool.
