☕ You warm up your coffee.
🚗 You warm up your car.
📩 But you’re still sending cold emails… with a cold inbox?
That’s what Mailreach is built to fix.
It promises better inbox placement using real inbox interactions, not hacks. But does it actually work?
I dug through 100+ reviews across G2, Reddit, and private sales communities to find the truth, not the hype.
Here’s what you’ll get in this review:
- Does Mailreach really improve inbox rates?
- Is it worth the monthly price?
- What are users loving (and complaining about)?
- And are there better options if I need more than a warmup?
Let’s break it down, simply, honestly, and backed by real user feedback.
TL;DR
- Mailreach is an email warmup tool that simulates real inbox activity to improve deliverability.
- It connects to your Gmail, Outlook, or SMTP inbox and runs automatic warmup every day.
- 100+ user reviews say it works fast, often improving inbox rates in under 2 weeks.
- Users love its ease of use, reputation scoring, and safe warmup automation.
- But it lacks outreach features, real-time blacklist alerts, and DNS monitoring.
- Best for: agencies, cold email consultants, and SDR teams managing multiple inboxes.
- Not ideal if you're a solo sender or need everything in one tool.
🧠 Pro tip: Pair Mailreach with Warmforge to protect your domain reputation while you warm up.
What Is Mailreach & How Does It Work?
Mailreach is an email warmup tool. Its job is to help your emails land in the inbox, not in the spam folder.
If you’ve ever sent cold emails from a new or unused inbox and noticed low open rates, the problem might not be your email content; it could be your sender reputation.
Email providers like Gmail or Outlook look at your email activity and decide whether to trust you.
And if your inbox has no reputation, they often flag your messages as risky.
Mailreach solves this problem by creating safe, daily email activity on your behalf. This builds your reputation slowly over time, the right way.
📨 Step 1: Connect Your Inbox
- Supports Gmail, Outlook, and SMTP
- Setup takes just a few minutes
- Safe, secure connection
- No manual steps after this
🔁 Step 2: Simulates Real Email Activity
- Sends/receives small daily warmup emails
- Uses a real inbox network (not dummy accounts)
- Messages get opened, replied to, and archived
- Builds trust with Gmail, Outlook, etc.
🤖 Step 3: Replies Like a Real Human
- Your inbox sends warmup emails
- Mailreach auto-opens and replies
- Creates real interaction threads
- Looks like normal usage to providers
📊 Step 4: Tracks Inbox Health in Real-Time
- See % of emails landing in the inbox vs spam
- Get alerts for blacklist issues or deliverability drops
- Track sender score, IP/domain health
- Know exactly when you’re ready for cold email
🛠️ Step 5: Runs Silently in the Background
- All warmup activities are stored in a hidden folder
- Doesn’t interfere with your real inbox
- No clutter, no risk
- You send real emails — Mailreach handles the warmup
✅ That’s it. Warmup without lifting a finger, just clean inbox signals, every day.
Final Outcome: An Inbox Ready for Cold Email
After a few weeks of warmup, your inbox will have a strong sender reputation.
That means your cold emails have a much higher chance of landing in inboxes, not spam folders.
Mailreach helps make sure the emails you send are actually seen.
That’s how it works, and why it’s trusted by teams serious about deliverability.

Users pointed out that this is what separates it from cheaper tools that blast generic messages that providers learn to ignore.
📈 Tracking That Shows You’re Improving

⚠️ What People Criticize About Mailreach
💸 Too Expensive for Solo Operators
Many solo users and indie founders felt Mailreach’s $25/inbox/month pricing was steep if you’re only warming one or two accounts.
Agencies felt it was worth it, but smaller users wanted a cheaper tier.

🧊 Doesn’t Replace Outreach Tools
Some first-time users expected Mailreach to also send cold emails, but it doesn’t. It’s strictly a warmup platform.
If you want to send cold campaigns, you’ll need to pair it with another tool like Smartlead, Instantly, or Mailforge.
🔍 Spam Tests Not Always Reality-Proof
A few users noted a mismatch between Mailreach’s spam test reports and actual cold campaign results.
Some inboxes showed 90% inboxing in the dashboard, but open rates told a different story.
These users pointed out that while Mailreach simulates good activity, your domain config and cold copy still play a huge role.
🐢 Dashboard Gets Sluggish at High Volume
Agencies managing 30+ inboxes said the interface starts slowing down, and there’s no bulk-editing to save time.
Read the full user review
You have to check inboxes one by one, which adds friction when managing a large fleet.
🚫 Doesn’t Help if You Skip Technical Setup
Mailreach doesn’t handle SPF, DKIM, or DMARC setup, and users who skipped this said the warmup wasn’t enough to get good results.
Some blamed the tool when inboxing stayed low, but experienced users clarified that domain hygiene must come first.
“It won’t fix bad DNS or spammy content. You still have to do things right.”
What All This Means If You're Considering Mailreach
If deliverability is your bottleneck, Mailreach users say it’s the one tool that consistently moves the needle, without wasting time or risking your domain.
Tools That Pair Well With Mailreach
Mailreach helps you fix your deliverability. But that’s just the first step.
To actually run cold campaigns that convert, you’ll need the right supporting tools for sending, personalization, lead enrichment, and automation.
Here are the top tools Mailreach users often pair it with:
🔥 Warmforge - Deliverability Safety Net
While Mailreach warms your inbox, Warmforge adds real-time blacklist monitoring, sender score alerts, and DNS checks. Think of it as your inbox reputation dashboard.

Why pair it: Healthy inbox + enriched leads = cold email that converts.
📥 Instantly - Sending Platform With Volume Focus

Mailreach Pricing (And Is It Worth the Money?)
Let’s talk about how much Mailreach costs and whether it’s really worth paying for.
Starter Plan – For 1 to 5 Inboxes
If you’re warming up just one inbox (or up to five), you’ll pay $25 per inbox each month.
This is the Starter plan. It gives you full access to everything:
- Daily warmup
- Health tracking
- Spam monitoring
- Inbox reports
You don’t miss out on any features just because you’re starting small. It’s a good choice if you’re testing Mailreach for the first time.
Scale Plan – For 6 to 20 Inboxes
Once you go above five inboxes, Mailreach reduces the price.
From 6 to 20 inboxes, the cost drops to $19.50 per inbox per month.
This plan is ideal for teams or consultants managing multiple accounts. You still get everything included, just at a lower per-inbox price.
Larger Volumes – 20+ Inboxes
If you manage 20 or more inboxes, the price drops again.
- At 20+ inboxes, each one costs $18/month
- At 50+ inboxes, the cost goes as low as $16/month
This is great for agencies, sales teams, or cold email pros running high-volume outreach.
Every inbox you add has its own tracking, score, and reputation control.
What About Spam Test Credits?
Mailreach also lets you test where your real emails are landing in the inbox, spam, or promotions.
You get 20 free spam test credits every month. If you need more, you can buy them separately.
They start at around $28 for 100 credits, and go up based on how many you want. These are optional and don’t renew automatically.
Is There a Free Trial?
No, Mailreach doesn’t offer a free trial.
But every paid plan gives you full access from day one, even if you’re using just one inbox.
There’s no public refund policy either. Most people start with one inbox, watch how their spam rate drops, then upgrade once they see results.
Is Mailreach Worth the Money?
If inbox placement is critical to your business, and you’re sending cold emails consistently, then yes, Mailreach is worth it.
Many users who struggled with spam saw results in less than two weeks.
For agencies and sales teams managing multiple inboxes, the cost per mailbox feels like insurance, and often pays off by saving a domain from being burned.
But here’s the honest truth:
While Mailreach is great for warmup, it doesn’t cover everything you need to run safe, high-performing cold outreach at scale.
What Mailreach Doesn’t Cover (But You Still Need)
This is where most people overestimate what Mailreach can do.
They assume it monitors all the behind-the-scenes issues that affect deliverability. But it doesn’t.
It doesn’t:
- Alert you if your domain gets blacklisted
- Monitor your sender score over time
- Notify you if your SPF/DKIM records break
- Track infrastructure-level risks across inboxes
- Catch problems from being on a shared IP block
- Or warn you before a deliverability issue hits
That means you might be warming your inbox just fine, while your domain is silently being flagged or your IP is part of a blocklist you didn’t know about.
To stay ahead of these risks, cold emailers often layer in a second line of defense, something to keep watch while Mailreach warms.
Why Cold Email Pros Pair Mailreach with Warmforge
Warmforge is built for that second layer.
It monitors your entire email infrastructure and reputation in real-time, so you know if something breaks before your campaigns suffer.
Here’s how Warmforge fills the gap:
📉 Real-Time Blacklist Monitoring
It scans 100+ global blacklists and alerts you instantly if your domain or IP gets flagged. You don’t have to find out the hard way when your open rates suddenly drop.
🔔 Sender Score & Reputation Alerts
Your sender score is like your email credit score. If it tanks, even warmed emails get blocked. Warmforge watches it daily and sends alerts when it dips.
🛡️ DNS & Domain Health Checks
Warmforge checks SPF, DKIM, DMARC, MX, and other records daily. If something’s missing or broken, it tells you; no guessing.
🕵️ Shared IP Visibility
Many users don’t realize they’re on a shared sending infrastructure. If someone else’s behavior gets the IP flagged, your emails suffer too.
Warmforge alerts you to shared IP issues you’d never spot on your own.
🚨 Proactive Alerts = Fewer Surprises
Instead of reacting after inboxing drops, you’ll know early and can pause or rotate before damage is done.
Mailreach builds trust. Warmforge protects it.
And in cold email, you need both.
Final Verdict: Should You Buy Mailreach?
If your cold emails aren’t landing in inboxes, Mailreach is a smart investment.
It handles warmup reliably, improves sender reputation, and gives you a clean path to start sending, especially if you’re managing multiple inboxes or new domains.
But it’s not an all-in-one solution. It won’t send your campaigns or monitor technical issues behind the scenes.
That’s why many teams pair it with:
- Warmforge for blacklist and DNS monitoring
For serious cold emailers, Mailreach is worth the cost. Just make sure the rest of your stack is ready too.
⚡ Want to monitor your domain reputation while you warm up?
Warmforge keeps an eye on blacklists, sender score, and DNS issues, so you stay safe while Mailreach does the warming.
