We’ll admit: Lemwarm was one of the first email warmers.

They were early to the game. Like others, they helped popularize the idea that your sender reputation needed active maintenance.

Credit where it’s due.

But Lemwarm hasn’t evolved.

It’s packed with cosmetic features and lightweight that don’t move the needle.

Their spam test is unreliable.

Their spam test is unreliable.

The only reliable way of measuring deliverability is to send emails to a list of addresses and check where they land.

Lemwarm skips this entire process. You send an email to only one address.

That means:

You don’t see how your email performs across Gmail, Outlook, Yahoo, and others.

You can get a “perfect score” and still land in spam.

Critical insights—like content-based spam triggers—are totally missed.

“Industry-based warmup” is just fluff.

Whether your test inboxes pretend to be in SaaS, healthcare, or real estate doesn’t matter to Gmail or Outlook.

What matters? Sender reputation. And Lemwarm’s “industry targeting” has *zero* impact on that.

Templated warmup content hurts more than it helps.

You get to warm templates and choose your warmup topic, but these features do not actually improve your sender reputation.

They can hurt your deliverability if they don’t align with email best practices.

When reputation drops, you need more than 40 emails/day.

Lemwarm’s cap might hold steady under perfect conditions, but reputation isn’t always stable.

If your domain ever gets flagged, or you’re starting cold—you’ll need more volume to bounce back and maintain a strong reputation.

Lemwarm isn’t built by deliverability experts.

It’s an add-on product inside Lemlist, not a standalone solution created by a team that lives and breathes sender reputation.

Their pricing punishes growth.

Starts at $24 per mailbox, no discounts. That adds up fast if you’re warming multiple accounts.

MailReach ranks superior. Up to 100/day warmups. Real-time monitoring. Inbox-first approach.

Hadil Filali
Co-Founder of Sparkline

We run warm up for multiple clients, and we therefore evaluated a LOT of tools on the market before settling on Mailreach as the best solution. The main reason for this was the multiple layers of conversation that its bots carry out i.e. mimicking true human email behavior, rather than just sending out a single email, as a lot of other tools do.”

Andrew Nicholson
CEO @ Kulea MA

“Was landing in spam for all Google professional & Personal accounts 100% of the time. Now I'm landing in the inbox 100% of the time and have my email configured perfectly. These guys are experts, highly recommend.”

Lewis Cowell
Founder @ Optimized

“MailReach is simple and effective. We've connected 2 of our accounts that were previously warming up through Instantly and Smartlead and after 30 days these 2 accounts had the highest deliverability out of all accounts we've had.”

CEO @ Peakflow

More reasons to choose MailReach for email deliverability.

Are Lemwarm and MailReach legit?
Lemwarm and MailReach are email automation solutions designed to warm up email addresses and associated domains.
As Lemwarm and MailReach are email automation solutions, they need to be connected to a mailbox and be able to open and send emails, reply, mark as important, remove from spam and categories, archive, etc.
The customers give the authorization to these tools to do all these actions. These actions can be done using the official Google or Microsoft API or via SMTP.
Given the above, email warming tools like Lemwarm or MailReach are using regular email automation protocols to make thousands of inboxes exchange emails, open them, mark some as important, remove from spam, etc.
Both are legitimate email warmup solutions, but MailReach offers more reliable, effective features to help improve your deliverability.
Why not choose a free email warm-up tool?
Unfortunately, from what we’ve seen and based on feedback from our users, free email warmup tools have several problems.
Some of these problems are shared with paid warmup tools as well.
For example, these tools use gibberish content in the emails which is obviously fake and can be easily identified by the email providers.
Also, their behavior and features are very limited and this has an impact on the efficiency of these solutions.
What is email warmup?
Email warmup is a process where automated emails are gradually sent from a new or inactive email account to build its reputation with email providers. This helps prevent emails from landing in spam and improves deliverability.
Tools like MailReach or Lemwarm handle the warmup process by engaging with these emails in a natural way—opening, replying, and marking them as important—so email providers recognize the account as trustworthy and ready for outreach campaigns.

Don’t let gimmicks eat your budget—or your deliverability.

MailReach is your modern, no-fluff deliverability solution with stronger spam protection, smarter warmup, and pricing that makes sense.
