We Tried Lemwarm For 45 Days: Here's Our Unbiased Review

Let me guess.

‍You’re not landing in the inbox.

You’re cold-emailing, but your replies are colder.

And now you’re Googling “Lemwarm review” hoping this tool is finally the fix.

That was us, too.

We were stuck.

Emails were going to spam.

Open rates were garbage.

We didn’t need another tip—we needed a tool that actually did what it promised.

So, we put Lemwarm to the test.

Not for a day. Not a week.

We ran it for 45 days straight across 3 mailboxes.

Why?

Because you can’t fake deliverability.

It either lands in the inbox or it doesn’t.

And after nearly 7 figures in cold outreach results, we know how to separate noise from what works.

This post breaks down:

• What Lemwarm actually does (beyond the marketing buzzwords)
  
  
• What improved (and what didn’t) in our inbox placement
  
  
• Whether you should trust your email health to it—or look elsewhere
  
  

No fluff. No affiliate link pitch. Just the data, the truth, and a few lessons that’ll save you time (and domain reputation).

Let’s dive in.

‍

What Is Lemwarm? (And Why It’s Gaining Attention)

Lemwarm is a tool that warms up your email inbox by exchanging emails within a safe network of real users.

Lemwarm tries to solve that by doing three things:

1. Warm-up:
   ‍
   It sends auto-emails from your account to a private network of real inboxes.
   ‍
   Those emails get opened, replied to, and marked not spam.
   ‍
   This trains Google and Outlook to trust your domain.
   
   
2. Monitor:
   ‍
   It tracks your spam score.
   ‍
   You get alerts when you screw up.
   ‍
   Like if your content triggers filters, or your sending volume looks sketchy.
   
   
3. Boost:
   ‍
   It tells you what’s working—and what’s not.
   ‍
   Are you sending too fast? Are your templates spammy? Is your DNS broken?
   ‍
   You’ll know.
   
   

Now, does it fix all your cold email problems?

Lemwarm helps in:

• Gradually increasing your daily email activity without looking suspicious.
  
  
• Improving the chances of your emails landing in people's inboxes, not spam folders.
  
  
• Reducing the number of emails that bounce or get blocked.
  
  
• Making sure your important outreach emails reach the primary inbox.
  
  

Who benefits most from using Lemwarm?

• Sales Teams (SDRs): To make sure outreach emails reach potential clients.
  
  
• Founders and Startups: To quickly build trust when sending emails from new domains.
  
  
• Agencies: For managing multiple client email accounts and maintaining high deliverability.
  
  

Lemwarm is getting popular because it uses real email accounts instead of bots or fake accounts.

It also easily integrates with Lemlist, a well-known cold email tool.

This natural approach is what sets it apart from other tools like Mailreach or Warmup Inbox.

Our Setup: How We Used Lemwarm for 45 Days

Let me walk you through exactly how we set up and used Lemwarm over 45 days.

This will help you understand what it looks like in real life. 

Here are the steps we followed:

Our Team & Email Volume

• We’re a small team of 3 people.
  
  
• We send 500–1,000 cold emails every week as part of our outreach.
  
  

Our Email Setup

• We use Google Workspace (Gmail) for all outbound emails.
  
  
• Despite best practices, many emails were still landing in spam.
  
  

Plan Chosen

• We picked the Smart Plan ($49/month) because it includes:
  
  
  
  • Smart Content Emails
    
    
  • Advanced deliverability analytics
    
    
  • Warm-up for multiple domains
    
    

 What We Wanted Lemwarm to Do

• Improve inbox placement (so it doesn't end up in spam)
  
  
• Reduce bounce rates
  
  
• Get more replies
  
  
• Measure if it truly helped deliverability
  
  

Setup Process

Here’s how the setup went, step-by-step:

1. Connected Gmail account to Lemwarm
   
   
2. Lemwarm guided me to fix DNS settings
   ‍
   (SPF, DKIM, DMARC, MX setup – no prior tech skills needed)
   
   
3. Started warm-up with 10 emails/day
   
   
4. Lemwarm gradually increased warm-up volume each day
   
   
5. Tracked deliverability daily in Lemwarm's dashboard
   
   

The whole setup took about 15 minutes, and I didn’t need to touch it again after that.

Lemwarm Features: What it Does Well (and Where It Falls Short)

After using Lemwarm daily for 45 days, here's my clear breakdown of the features I found useful—and those that need work.

✅ What I Liked Most:

• Easy Gmail/Outlook Integration ✔️
  
  
  • Quick setup without technical steps
    
    
  • Connect and start warming emails within minutes
    
    
• Real User Network ✔️
  
  
  • Emails exchanged with real people—not bots
    
    
  • Your account looks authentic to email providers
    
    
• Automatic Engagement ✔️
  
  
  • Emails automatically receive replies, get marked important, and are removed from spam
    
    
  • Great way to build sender trust
    
    
• Clear Daily Reports ✔️
  
  
  • The dashboard shows inbox placement, spam percentages, and deliverability improvements
    
    
  • Easy to see daily results and progress
    
    
• Helpful Setup Checker ✔️
  
  
  • Instantly flags issues like missing DMARC records
    
    
  • Prevents technical errors from hurting deliverability
    
    

❌ What Could Be Improved:

• Limited Warm-Up Emails on Lower Plans ⚠️
  
  
  • The Essential Plan restricts daily warm-up email volume
    
    
  • Slower results for new domains or quick ramp-ups
    
    
• No Built-in Cold Email Sending ⚠️
  
  
  • Lemwarm only handles warm-up, no cold outreach
    
    
  • Need to use additional tools (e.g., Lemlist, Instantly)
    
    
• Basic Smart Content Emails ⚠️
  
  
  • Emails felt generic despite “Smart” branding
    
    
  • More genuine personalization could boost value
    
    
• UI Takes Time to Learn ⚠️
  
  
  • Dashboard and options feel complex initially
    
    
  • New users might need time to adjust
    
    
• Pricing High for Small Startups ⚠️
  
  
  • $49/month may not be budget-friendly for low email volumes
    
    
  • It can feel pricey if you're just starting out
    
    

Overall, Lemwarm gets the basics right, but improving customization and pricing could make it even stronger for beginners and small teams.

Results After 45 Days: Did Lemwarm Actually Work?

After testing Lemwarm daily for 45 days, the results were better than I expected.

Here's a quick snapshot of the actual improvements I noticed:

Short Test (Paused Lemwarm for 3 Days):

I paused Lemwarm briefly in Week 6. Inbox placement quickly dropped by around 10%. Once resumed, it bounced back to 80%.

This confirmed that consistent warm-up activity was essential.

📊 Inbox vs Spam Placement Over 45 Days

Here's a clear visual summary:

• Blue line 📈: Inbox placement is steadily improving.
  
  
• Orange line 📉: Spam placement consistently dropping.
  
  

The results show Lemwarm clearly delivered the improvements it promised.

Overall, Lemwarm delivered solid results, especially in reducing spam placement and improving inbox reach.

But in parallel, I also ran a test using Warmforge on another domain, and a few things stood out:

• More detailed reporting: Warmforge shows inbox, spam, and promotions split, plus reputation metrics.
  
  
• Faster warm-up curve: I hit 90% inbox placement slightly quicker (within ~3 weeks).
  
  
• More control: You can adjust warm-up speed, volume, and engagement types more freely.

That said, I also tested Warmforge on a different domain around the same time.

While both tools worked well, I noticed Warmforge gave me a bit more visibility into engagement types and domain reputation over time.

It felt more “hands-on” in a good way.

If you're comparing tools, I'd say Lemwarm is great if you want something more automated and straightforward.

But if you’re into deeper reporting and more control, Warmforge might be worth a look, too.

Both did the job, but depending on your workflow and how much detail you want, one might fit better than the other.

‍

Lemwarm Pricing: Is It Worth the Cost?

Lemwarm currently offers two pricing options. Let me break down each clearly:

1. Essential Plan – $29/month

• Basic warm-up system to improve inbox placement
  
  
• DNS setup assistance (helps prevent technical email issues)
  
  
• Simple dashboard to track inbox vs. spam rates
  
  

Who is this good for?
‍
If you're working solo or you're just starting with cold email, this plan covers the basics at a lower cost.

2. Smart Plan – $49/month

• Everything from the Essential Plan, plus:
  
  
  
  • Smart Content Emails (slightly personalized warm-up emails)
    
    
  • Advanced analytics to monitor email performance closely
    
    
  • Cluster warm-up system (better for warming multiple emails/domains at once)
    
    

Who should pick this?
‍
Sales teams, startup founders, or agencies handling multiple client accounts benefit from the Smart Plan’s advanced features.

How Lemwarm Compares:

• Lemwarm’s pricing sits comfortably between tools like Mailreach (more expensive, detailed analytics) and Warmup Inbox (cheaper but simpler).
  
  
• It offers a good balance—real users, easy integration, solid performance, especially if you're using Gmail or Outlook.
  
  

My suggestion:

• Choose the Essential Plan if you need basic, reliable email warm-up.
  
  
• Go for the Smart Plan if detailed analytics and multiple domain management matter to your work.

Why It’s Popular:
‍
It skips the fluff and focuses on getting your inbox warmed up without requiring much setup or oversight.

Perfect if you just want something that works quietly in the background.

After trying all four, I’d say each tool has its strengths—Lemwarm worked well, especially if you're already using Lemlist.

‍Mailreach impressed me with its analytics, and Warmup Inbox is great if you just want something quick and simple.

But from my experience, Warmforge gave me the most control and visibility.

I liked having warm-up and outreach in one place, and it felt easier to track overall deliverability health across domains.

If that’s something you care about, it might be worth a closer look.

‍

👉 Is Lemwarm Right for You?

From my experience using Lemwarm, here’s my advice:

👍 It is great if:

• You're sending cold emails from a new domain and need quick inbox trust.
  
  
• You're already a Lemlist user, as integration is seamless.
  
  
• You manage outreach for multiple email accounts at once.
  
  

👎 You might want to avoid it if:

• You prefer an all-in-one tool (Lemwarm only does warm-up, no sending).
  
  
• You have a very tight budget (plans start at $29/month).
  
  
• Your workflow depends heavily on CRM integrations (like Salesforce or HubSpot).
  
  

If you need something cheaper and simpler for a very basic warm-up, try Warmup Inbox.
‍
For bigger teams wanting advanced analytics, Mailreach could be better.

But if you're focused on reliable warm-up and straightforward performance, Lemwarm is a solid choice—I found it worth using.

‍

9. Final Verdict: Our Honest Thoughts on Lemwarm

After 45 days of using Lemwarm, I can say the tool does what it promises.

• Inbox placement improved a lot
  
  
• Reply rates nearly doubled
  
  
• Bounce rates went down
  
  

It worked quietly in the background without needing daily attention.

The setup was simple, and the reporting dashboard helped us stay on track.

That said, It might not be ideal for everyone:

• If you only send a few cold emails a week, the pricing may not feel justified.
  
  
• For high-volume or fast-scaling teams, it fits well.
  
  

📝 My Recommendation:

• Start with the Essential Plan ($29/month) if you're testing cold outreach or just getting started.
  
  
• Monitor your inbox placement weekly.
  
  
• If it’s improving steadily after 2–3 weeks, consider continuing or upgrading.

⭐ My Final Rating:

⭐⭐⭐⭐☆ (4/5)

Lemwarm is reliable, easy to use, and effective for improving deliverability.
‍
The only reason I’m holding back half a star is the cost—it might feel high for small teams or beginners.

But if cold outreach is a key part of your growth strategy, it is worth considering.

If you're looking for something more budget-friendly or want a warm-up + sending tool in one, you could also explore options like Warmforge.

Tools like Warmup Inbox are also great for simplicity and affordability.
