7 Best MailMonitor Alternatives in 2025

So, MailMonitor wants you to pay $99 just to run 5 inbox placement tests a month.

And what do you get for that? A basic spam score, a few blacklist checks, and… that’s about it. No help with SPF or DKIM. No spam trap alerts. No email previews.

If you’ve already paid for it and feel like you didn’t get your money’s worth, I feel you. If you’re just here doing research before spending that kind of money, smart move.

Either way, you’re in the right place.

I’ve tested a bunch of deliverability tools recently and found 7 solid alternatives that give you way more value than MailMonitor,  some of them even free.

In this list, you’ll find:

• Tools packed with features like inbox placement, spam trap alerts, and DMARC monitoring
• Budget-friendly (and even free) options for solo users
• Enterprise-grade tools for large outreach teams

Let’s get into it.

TL’DR: Top 3 MailMonitor Alternatives Compared

To help you quickly choose a MailMonitor alternative that works for you, I’ve created a detailed table comparing all the major features of the top 3 platforms:

My List of the 7 Best MailMonitor Alternatives in 2025

To compile my list of MailMonitor alternatives, I first tried several inbox placement tools and spam tester tools (and still spent less than I would have on a MailMonitor subscription!).

Here’s how my list stacks up:

1. Inbox Radar by Saleshandy
2. GlockApps
3. Folderly
4. ZeroBounce
5. Allegrow
6. InboxAlly
7. MailReach

Let’s get into the breakdown of each tool!

1. Inbox Radar by Saleshandy

Inbox Radar by Saleshandy is first on my list of MailMonitor alternatives. 

Its basic plan costs just $23/month (annual billing) and lets you run 15 tests compared to MailMonitor’s 5 tests for $99/month!

Inbox Radar uses a seed list of highly reputable B2B emails to help you test across different email service providers like Gmail, Outlook, Yahoo, etc. 

It checks all the key things that affect whether your email lands in the inbox or spam:

• Content issues (like spammy words or formatting problems)
• Email authentication (SPF, DKIM, and DMARC setup)
• Blacklist status of your domain and IP
• Spam triggers that could hurt your chances

And the best part? It gives you clear, simple tips to fix those issues and improve your deliverability.

With Inbox Radar, you can run inbox placement tests in two simple ways.

One, you can test a single email manually, just to see where it lands.

Two, you can set it on autopilot to test your emails regularly, either before your campaign goes live or while it’s running. 

What Makes Inbox Radar Even Better?

It’s built right into your Saleshandy account.

That means you don’t have to switch between tools or run tests separately.

You can see real-time inbox placement and spam health while setting up your campaign, and optimize your campaigns instantly based on the results.

Pricing  (Billed Annually)

• Inbox Starter: $23/month
• Inbox Pro: $79/month

2. GlockApps

Next on my list of MailMonitor alternatives is GlockApps.

It’s a dedicated tool you can use to run inbox placement tests and ensure that your email authentication records are working properly. 

GlockApps has a decent email seed list that spans four major ESPs: Gmail Workspace, Outlook, Yahoo, and AOL.

It also offers an in-depth analysis of three major aspects of your emails:

• Deliverability: Inbox, others, spam, or missing.
• Content: Images, HTML, link count, and preview.
• Authentication: SPF, DKIM, DMARC, and DNS records.

What I like about GlockApps is that you don’t have to sign up for even a free trial to run spam tests. However, you only get two spam tests with the free plan. 

But here’s the catch: GlockApps won’t tell you how to improve your deliverability unless you sign up for a paid plan. 

So, if you’re either a high-volume sender or need detailed insights, you’ll have to go for the essential plan (I’ve listed the pricing below).

GlockApps Pricing Plans  (Billed Annually)

• Essential: $59/month
• Growth: $99/month
• Enterprise: $129/month

3. Folderly

Another good MailMonitor alternative is Folderly.

It is an email warmup tool that also helps you check your inbox placement through detailed spam tests.

You can simply connect your mailbox with Folderly, choose a template, and run a manual test. Alternatively, you can also automate your inbox placement tests. 

Based on its tests, Folderly will send you detailed reports of your inbox placement rate. It’ll also give you insights into your IP and domain health, including blacklist verification status.

However, Folderly is more than just an inbox placement checker.

It also helps you warm up your email domain, set up your email authentication records, and generate AI-powered email copies.

Folderly Pricing Plans

Folderly offers only one plan, which costs $64/month with annual billing or $79/month with monthly billing.

With the paid plan, you can perform unlimited inbox placement tests. However, Folderly charges you separately for all other functionalities (like email warmup).

4. ZeroBounce

Next on my list of MailMonitor alternatives is ZeroBounce. It is an email verification tool that also offers detailed inbox placement monitoring services.

I found ZeroBounce’s spam testing process quite clunky and slow: I had to copy a seed list of emails it gave me and manually send the test email from my account.

However, I did like the placement report it generated: I could see the result of the placement test for each email address, along with their location, ESP, and even location in some cases.

On the other hand, when I tried to understand why some of the emails went to spam, I couldn’t find any insights or recommendations I could use to improve my deliverability.

All I could see was a lot of technical information about email headers that would confuse the average user.

All in all, I would say that it is a decent tool that can do limited testing but isn’t well-suited for running rigorous tests. 

ZeroBounce Pricing Plans (Billed Annually)

• Starter: $49/month
• Team: $99/month
• Pro: $249/month

5. Allegrow

Allegrow is an AI-powered MailMonitor alternative.

It uses a seed list of real B2B email accounts to test your emails’ inbox placement and analyzes the deliverability through a proprietary algorithm.

It’s a good option for high-volume senders or sales teams with multiple users. This is because Allegrow provides detailed reports on the inbox placement rate for different accounts, departments, and domains.

So, you can easily identify which areas require improvement and which accounts have the highest inbox placement rates. 

Plus, you can also get placement data for different versions of your emails, so you know which one is likely to make it to inboxes.

Apart from this, Allegrow also helps you clean email lists by removing invalid emails and spam traps so you can minimize your bounce rate. 

However, Allegrow only offers spam testing capabilities with its expensive plans, starting at $540/month.

Allegrow Pricing Plans

• Premium Unlimited: $540/month
• Scale Plus Unlimited: $1,340/month

6. InboxAlly

InboxAlly is an email deliverability platform that offers email warmup and spam testing capabilities. 

It offers a free spam checking service, which will give you a basic report on your email’s content, headers, and authentication records. 

However, InboxAlly’s spam testing with its paid plans is much more comprehensive. 

It’ll send your email to multiple recipients, give a detailed breakdown of which emails landed in what folder, and even whether your recipients opened the emails. 

As an advanced email deliverability tool, InboxAlly also gives you recommendations on how to improve your email deliverability by fixing key issues.

If you just need to check your email template, you can use InboxAlly’s free content testing feature.

Plus, you can ask it to “Fix Your Email” for free, and it will remove spammy words from the copy.

InboxAlly Pricing Plans

• Starter: $149/month
• Plus: $645/month
• Premium: $1,190/month
• Enterprise: custom pricing

7. MailReach

Last on my list of the best MailMonitor alternatives is MailReach.

It is a spam testing, deliverability, and email warmup tool.

MailReach runs thorough inbox placement tests by sending emails to multiple professional or personal accounts based on your preferences.

MailReach then checks your emails’ authentication setup, content, image-to-text ratio, and HTML script so that you know the reasons behind your email deliverability. 

After running an inbox placement test, I noticed that MailReach only sent test emails to Outlook and Gmail Workspace accounts. This might be an issue if you want to target a specific ESP like AOL or Yahoo.

However, it did provide a detailed breakdown of the setup and content of my email. So, MailReach doesn’t offer too many useful suggestions, but gives a decent, comprehensive analysis nonetheless.

MailReach Pricing Plans (Billed Annually)

MailReach offers volume-based pricing for its spam tester credits.
You have to buy a minimum of 25 credits that cost $9.6/month (plus taxes).
The per-credit price drops as you buy more credits, and MailReach offers custom pricing if you need 2,000+ credits/month.
