This email verification tool promises to clean your list, predict inbox placement, and protect your sender reputation.
But does it actually deliver on its promises?
We scoured the web for real reviews, and the results were… mixed.
Some users love its simplicity, while others call out missing features and accuracy concerns.
So, is MailerCheck the right fit for your email marketing?
What is MailerCheck?
MailerCheck is a tool that helps businesses improve email deliverability. It verifies email lists, tests inbox placement, and analyzes email content.
It checks for syntax errors, invalid addresses, and potential spam triggers to keep emails out of spam folders and in front of the right audience.
With its email verifier, you can validate single addresses, upload bulk lists, or run real-time checks through an API.
Email insights highlight issues like:
- spam words,
- broken links,
- and blocklist appearances.
At the same time, inbox placement tests predict where emails will land before you send a campaign.
Businesses use MailerCheck for a variety of reasons.
Some want to protect their sender reputation, while others wish to reduce bounces. Saving money by keeping email lists clean is another driver.
The tool tracks domain activity, generates usage reports, and helps marketers make strategic decisions based on reliable insights.
Key MailerCheck features
Let’s break down how each feature of MailerCheck works.
Clean your email list to improve deliverability
A messy email list can hurt your email deliverability.
Invalid addresses, typos, and outdated contacts lead to problems such as:
- bounces,
- spam complaints,
- and wasted money on emails that never reach anyone.
MailerCheck’s email verifier helps you remove bad addresses so your emails reach real people. Just upload your list, and you’ll get results in seconds.
Get more than just a clean list – gain insights
Fixing bad emails is great, but knowing why they’re bad is even better. MailerCheck gives you email insights that go beyond verification.
You’ll see which emails are risky, which ones might still work, and get recommendations for list maintenance.
This helps you decide whether to tag, remove, or separate specific contacts.
Test your emails before you hit send
Your email might look perfect, but that doesn’t mean it’ll land in the inbox. Spam filters scan for spam folder triggers like broken links, blocklists, and spam-like words.
MailerCheck analyzes your email content so you can fix these red flags before sending.
That means fewer emails get lost, and more people see your message.
Predict if your email will reach the inbox
What if you could know where your email will land before you send it?
With inbox placement testing, MailerCheck runs your email through providers like Gmail and Outlook.
You’ll see if your message will end up in the spam folders, inbox, or blocked entirely – so you can make changes before it’s too late.
Filter out bad emails in real time
MailerCheck’s real-time email verification API checks email addresses as they’re entered.
When someone signs up, you’ll know immediately if their email is valid, saving you from collecting useless contacts that hurt your email deliverability.
Check the health of your email list
MailerCheck doesn’t just tell you which emails are bad. It gives you a complete picture of your list’s overall health.
With usage reports, you can track your emails’ performance across uploads, integrations, and API activity.
The better you understand your list, the better decisions you can make for your email marketing strategy.
Monitor your domain for suspicious activity
MailerCheck monitors your domain in real time so you can catch suspicious activity early.
This protects your emails from being flagged as spam and keeps your domain trustworthy.
Get alerts if you’re on a blocklist
MailerCheck scans major blocklists and notifies you if your domain or IP is flagged.
If that happens, you’ll know right away and can take steps to fix the issue before it affects your email campaigns.
Keep your email list in top shape
With MailerCheck, you get a full suite of tools to verify emails, analyze content, test email deliverability, and protect your sender reputation.

MailerCheck reviews
We searched the internet for user reviews on MailerCheck, and to be honest, there aren’t many.
Compared to other email verification tools, it doesn’t have a considerable presence on review platforms.
But we did find some feedback – both good and bad – mainly from small business users:
What users like
Many users praise MailerCheck for being easy to set up and use.
Pedro P. called it “quick to implement and easy to use. Even the most inexperienced users can use this tool with ease.”
Others appreciate how fast it processes email lists, like Cody C., who wrote, “I like the pay-as-you-go and the fact that once you start verifying the emails, it’s ready within a few minutes. No long delay.”
The MailerLite integration is another highlight. Govind R. said, “Instant integration with MailerLite and can start using the tool right away.” This makes it an easy choice for businesses already using that platform.
Where MailerCheck falls short
Some users feel the tool lacks certain features compared to other services.
Adam B. pointed out that, “For the price – it is missing a couple of features that other services have.” He also noted that MailerCheck sometimes invalidates more emails than expected, saying, “I also feel like it is invalidating a few more emails than other services. It has just basic categories for emails that have been checked when it should have a few more, like those emails that may bounce but are worth a try.”
Accuracy is a common concern. Alessandro G. mentioned that the tool has “too limited options in workflow automation. Need more triggers and actions.”
Cody C. also wished for more clarity on how MailerCheck works, saying, “I would say lack of education for the customer. WHY exactly are they different from Bouncify/NeverBounce? If they had a 1-2 min video explaining the backend details/complexity of how they verify emails (different).”
The better MailerCheck alternative
If you’re looking for a better email verification tool, Bouncer is the stronger choice.
While MailerCheck covers basic verification, some users mention concerns about accuracy and missing features (“I also feel like it is invalidating a few more emails than other services.” – Adam B.).
Bouncer delivers more precise verification results and has unique features that MailerCheck lacks.
Users praise its bounce prediction and email toxicity check, with Max G. saying, “With Bouncer, we immediately saw the effect: opening rates above 65%, 1 bounce in 100 sent.” It also handles catch-all email addresses, something many verifiers struggle with.
Another standout feature is free list sampling – you can check if your list needs cleaning before paying. Marisa M. highlighted this, saying, “I like how it gives you an estimate of how many emails may bounce before testing the addresses/using up the credits.”
If email verification is your top priority, Bouncer over-delivers where MailerCheck doesn’t. Try it for free and see the difference.
