5 Best GlockApps Alternatives in 2025
To compile my list of the 5 best GlockApps alternatives, I first ran spam tests across 10+ inbox placement tools. I evaluated them based on:
- Support for multi-inbox connections.
- Ease of use and integrations.
- Pricing.
Here are the 5 GlockApps alternatives that stood out to me:
1. Inbox Radar by Saleshandy
Best for: Automating spam tests for cold emails with multi-ESP seed lists.
First on my list of GlockApps alternatives is Inbox Radar by Saleshandy.
It helps you test your inbox placement across multiple ESPs and get insights on how to improve your email deliverability.
Why Inbox Radar by Saleshandy is the Best Alternative to GlockApps
Inbox Radar is the best GlockApps alternative for 2 solid reasons:
First is pricing:
- GlockApps: 1 account for spam testing at $59/month (annual billing).
- Inbox Radar: Base plan starts at $23/month, and there is no restriction on the number of sending accounts you can connect.
Second, Inbox Radar gives you more options to customize your spam tests:
- Specific days and time zones for testing.
- Time interval between different tests.
- ESPs you want to target.
Additionally, as a safeguard feature, Inbox Radar automatically pauses your tests if your deliverability rate drops below a specified rate.
Pros
- Gives you tips and recommendations on how to fix the inbox placement rate
- Creates instantly shareable reports on your spam tests
- Comes with a clean interface that gives you an overview of your spam tests
Cons
- You get only one free placement test in the free trial
What Users Have to Say About Inbox Radar
Inbox Radar is a new product, so there aren’t too many reviews of it just yet.
Pricing (Billed Annually)
Inbox Radr has two pricing plans:
- Inbox Starter: 15 spam tests for $23/month.
- Inbox Pro: Unlimited spam tests $79/month.
2. MailReach
Best For: Anyone looking for spam testing and blacklist monitoring features in one tool.
MailReach is an email warmup and spam testing platform tool.
It offers decent inbox placement testing capabilities that analyze your deliverability, email copies, and authentication setup.
Why MailReach is a Good Alternative to GlockApps
MailReach is a good alternative to GlockApps if you want to run inbox placement tests across inboxes without paying $99/month.
Let me show you how much you’d end up paying for 1,000 spam testing credits on both platforms:
- GlockApps: $142/month (billed monthly).
- MailReach: $108/month (billed monthly).
And while GlockApps only lets you connect 10 accounts for spam testing, MailReach doesn’t place any such restrictions on you.
You can use your spam test credits however you want!
Pros
- You can upload your own seed list for spam testing
- Automatically rotates its internal seed list for the best testing results
- Also offers email warmup capabilities
- Sends you automatic alerts via Slack or webhooks if your email deliverability drops
Cons
- Offers very limited suggestions on how to improve deliverability
- Initial setup might be complex for beginners
What Users Have to Say About MailReach
MailReach has fairly positive reviews across G2, Capterra, and Trustpilot.
However, the problem is that I was unable to find any reviews specifically for the platform’s spam testing capabilities.
MailReach Pricing
MailReach offers volume-based pricing for its spam testing credits. You can either pay as you go or a monthly fee.
Here’s an example of what you’d have to pay for 1,000 test credits according to the two different plans:
- Pay-as-you-go: $54/month.
- Monthly: $43.2/month.

3. Folderly
Best For: Enterprises that want a single tool for both email warmup and spam testing.
Folderly makes my list of GlockApps alternatives as an enterprise-grade spam testing platform.
It offers both email warm-up and inbox placement capabilities.
Why Folderly is the Best Alternative to GlockApps
First, Folderly is way cheaper than GlockApps.
You can get unlimited spam testing credits for just $64/month (annual billing).
GlockApps doesn’t even have an option for unlimited inbox placement tests.
Second, it also offers detailed blacklist delisting guides to help you recover domains and accounts.
Pros
- Clean UI and detailed shareable test reports
- One-click mailbox integration for 10+ ESPs
- Monitors IP and ESP blacklists
Cons
- The pricing might be too expensive for SMEs, solopreneurs, and startups
What Users Have to Say About Folderly
Folderly has very positive reviews across G2, Capterra, and Trustpilot.
However, most reviewers have used Folderly for its email warmup capabilities.
I wasn’t able to find any specific reviews about its spam testing feature!
Folderly Pricing
Folderly offers separate products for email warmup and spam testing, each with its own pricing plans.
Its Inbox Insights (i.e., the spam checker) has only one plan:
- $79/month (monthly billing)
- $64/month (annual billing)
Both plans support unlimited spam tests.
4. MailGenius
Best For: Running one-off free spam tests.
MailGenius is one of the simplest spam testing tools you’ll come across.
It’s the ideal GlockApps alternative if you need unlimited spam test credits on a tight budget.
Why MailGenius is a Good Alternative to GlockApps
MailGenius beats GlockApps on only one thing: pricing.
You can get unlimited spam testing capabilities at just $39/month (annual billing).
And it only offers automated spam testing with its most expensive plan, and even that doesn’t use multi-ESP seed lists.
I did find it very easy to run a spam test on MailGenius.
It gave me a comprehensive analysis of my email copy and technical setup, along with a preview of my email across mobile, tablet, and desktop screens.
Pros
- Flexible pricing plans starting at $ 8 per month
- Supports API and white labeling solutions for agencies
- Comes with an AI deliverability agent that helps you improve your inbox placement
Cons
- MailGenius only sends test emails to one account rather than a seed list
- Does not offer detailed suggestions on how to improve inbox placement
What Users Have to Say About MailGenius
Most of the reviews of MailGenius on G2, Trustpilot, and Capterra are very old. I found only three reviews from 2024 or 2025.
One was positive, one negative, and one neutral.
Here’s what Romain said about his MailGenius experience on Trustpilot:
“Mailgenius report our domain as blacklisted but it’s not true. There is no way to understand why.”
I also came across other reviews that reported the same exact concern.
So, MailGenius might not be the most reliable tool when it comes to blacklisting information (which it offers along with the spam test report)!
MailGenius Pricing (Billed Annually)
- Newbie: $8/month (10 credits/month)
- Standard: $20/month (30 credits/month)
- Genius: $39/month (unlimited credits)
- Automated: $79/month (unlimited credits)
5. Unspam Email
Best For: Quick email spam testing across multiple ESPs.
Last on my list of GlockApps alternatives is Unspam.email.
It’s a minimalist spam checker you can use to make sure your newsletters and cold emails are making it to inboxes.
Why Unspam Email is a Good Alternative to GlockApps
Unspam email is a good GlockApps alternative for three reasons:
First, it has a cleaner UI/UX compared to GlockApps.
Second, it costs less than GlockApps:
- With Unspam Email, you can run tests from multiple inboxes starting at less than $9/month (annual billing).
- With GlockApps, you’d have to pay $59/month for connecting just 1 sending account.
Lastly, it comes with an AI-powered heatmap checking feature.
Through it, Unspam shows you which area of your email copy is getting the most attention from readers!
Pros
- Monitors IP and ESP blacklists for your domain and IP as part of the spam test
- Uses multi ESP seed lists for running inbox placement tests
Cons
- Does not support automated spam tests unless you get an API plan
What Users Have to Say About Unspam Email
Unspam Email has just 2 reviews on G2 – both from 2023.
On Trustpilot, it has 0 reviews. And it’s not even listed on Capterra.
Here’s a review from Luka on G2.:
“Overall, the combination of comprehensive analysis, user-friendly interface, actionable insights, free version, and accurate results make Unspam.email a valuable tool for anyone looking to improve their email deliverability.”
Unspam Email Pricing (Annual Billing)
