MailGenius gets some things right.

The email tester analyzes your email, and gives you a score and a diagnostic with improvements you can make.

Email-spam-test-report image

But it works like an email scanner, instead of an actual spam test.

MailGenius doesn’t test deliverability; it scans for best practices. The score is based on a checklist, not your mail’s actual inbox placement.
No inbox placement insights. You could get a perfect ‘score’ on MailGenius and still land in spam. Their scan can actually mislead you into thinking things are fine.
Limited to diagnostics without context. Their report skips the most important metrics for true inbox placement and real-world deliverability impact.
They’re also very consulting-heavy. You may need costly deliverability audits to dig deeper into email performance.

MailReach gets you mail insights that go beyond a scan and a score.

Real deliverability testing, not just scanning

MailReach doesn’t stop at a simple scan. We check actual inbox placement across dozens of inboxes, so you can see where your emails actually land.

Monitor and improve your sender reputation

MailReach’s warmup for B2B senders assigns you a Reputation Score. This helps proactively track and improve your sender reputation over time—something MailGenius can’t offer.

Actionable spam testing, no guesswork needed

We go beyond arbitrary scores with precise feedback on where your emails end up and why. Our free report is packed with accurate, actionable insights you can actually use.

Built-in warmup that boosts deliverability

Unlike MailGenius, MailReach’s warmup algorithm actively improves your email’s reputation and avoids spam folders. It’s a hands-on approach for measurable improvements.

More reasons to choose MailReach for email deliverability.

Are MailGenius and MailReach legit?

Mailgenius and MailReach are email automation solutions designed to warm up email addresses and associated domains.
As Mailgenius 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 Mailgenius 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 MailTester 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.

Is MailReach more expensive?

While MailGenius offers free testing, MailReach provides deeper insights at a low price of $25/month, ensuring you get better long-term results.

MailGenius’s limits can’t compete with MailReach’s performance.

Warmup Inbox may work, but MailReach offers a smarter, uncapped warmup solution that maximizes your sender reputation. Get real, powerful engagement and up to 100 warming emails per day—at a better value.

What is MailGenius?

MailGenius is an email deliverability service that helps companies improve their probability of reaching their recipients’ inboxes.

Concretely, MailGenius is composed of an email tester and deliverability consulting services.

The email tester analyzes your email, gives you a score and a diagnostic with improvements you can do.

Unfortunately, you can have a perfect score on MailGenius and still have a poor deliverability and land mostly in spam.

MailGenius can be interesting to run several checks such as blacklists, SPF, DKIM, DMARC records, links, HTML, etc.

Beyond these checks, MailGenius doesn’t measure your deliverability since it does not check where your email lands on several inboxes, which is the only real way to check email deliverability.

This is why, we’ll cover in this page, why MailReach is the best alternative to MailGenius.

How MailGenius and MailReach Spam Test work?

MailGenius : how does it work?

To use MailGenius’ email tester, you need to send your email to the testing address given by MailGenius and click on “See your score”.

The testing address given by MailGenius is different for each user and automatically generated to help them find your email in their system.

Once you click on “See your score”, you wait several seconds and then get your result.

A typical MailGenius diagnostic is composed of a score out of 100 and a list of several checks.

Among the checks done by MailGenius, there is :

  • SpamAssassin score
  • Reverse DNS
  • SPF, DKIM and DMARC
  • Email content check (HTML, images, etc.)
  • Domain, IP and body blacklists
  • Links
  • Etc.

When using the email tester of MailGenius, your email is scanned to find potential issues, but, you’re not able to find out your inbox placement on the major inbox providers.

The main limit of MailGenius’ tester is the score given. It’s not based on your deliverability so it can’t measure it.

Deliverability can only be measured by sending your email to a list of relevant inboxes (inboxes you really target) and analyze where your email lands on each of these inboxes.

This is exactly why that’s important to find a better alternative to MailGenius.

How MailReach Email Spam Test works?

MailReach Spam Tester is easy to use and user friendly. But, in order to help you get a more reliable diagnostic than MailGenius’, there’s one additional step to do.

This added step takes 2 seconds : copy a custom code given by MailReach and paste it inside your email body.

Once it’s done, send your email to a list of 30+ inboxes.

Compared to MailGenius, the way MailReach scores your deliverability is much more reliable because it’s based on where your email lands and not only by scanning your email (which is what MailGenius does).

Once you have added the custom code in your email and sent it to the list of addresses, you can click on “Get your score” and then find out your result.

A typical result from MailReach Email Spam Test is composed of your spam score with the detail of your inbox placement by provider and inbox type.

Unlike MailGenius, the spam score given by MailReach is 100% based on where your email landed on our list of 30+ mailboxes.

The score adapts according on the type of mailboxes you target. That’s crucial to measure your real deliverability.

You can see where your email landed on Gmail, Google Workspace, Office 365, Outlook.com, Hotmail, Yahoo, etc.

MailReach also analyzes your email content : known spam words, links problems, tracking, etc.

And as a MailGenius alternative, MailReach also checks that everything is fine with your sending setup : SPF, DKIM, DMARC, Blacklists, etc.

Why MailReach is more effective?

A man showings a check mark | mailgenius

MailReach as a MailGenius alternative :
Get a reliable spam score.

You can get a perfect score on MailGenius’ email tester and still land mostly in spam. MailGenius’ score doesn’t represent your real deliverability since it’s only based on a scan of your email.

Unlike MailGenius, MailReach analyzes your deliverability by checking where your email lands on a list of mailboxes well allocated between inbox providers. That’s the only reliable way to measure deliverability.

As a MailGenius alternative, the deliverability score displayed by MailReach is reliable, unbiased and is really based on your deliverability.

MailReach as a MailGenius alternative : Find out your inbox placement by inbox provider.

Unlike MailGenius, when running a spam test with MailReach you send your email to 30+ inboxes on the most important inbox providers.

MailReach, compared to MailGenius, looks for youur email in each mailbox and tells you exactly where it landed. You can’t have this precious information using MailGenius.

Find out your inbox placement on the major providers : Gmail, Google Workspace, Office 365, Outlook, Hotmail, Yahoo, etc. That’s not possible with MailGenius.

Inbox placement by provider | mailgenius
Image/text ratio rest | mailgenius

MailReach as a MailGenius alternative :
Get a helpful diagnostic to improve your score.

MailGenius gives a report which doesn’t contains all the most important elements to check.

Unlike MailGenius which does a SpamAssassin check (which is not the best to measure deliverability), MailReach checks for known spam words that can harm your deliverability.

As it’s now an important factor in deliverability, MailReach checks if there’s a tracking pixel in your email. MailGenius doesn’t check this.

MailReach as a MailGenius alternative : make up your own mind

The best option remains to try MailReach and compare it to MailGenius to find out which one helps you the most to measure and improve your inbox placement.

You can do 3 free spam tests per 24 hours and if you need more, you can buy credits.

But compared to MailGenius, you can count on MailReach’s Spam Test to really measure  on your deliverability and improve it 💪.
