11 Best Folderly Alternatives to Try in 2026 (And Pick the Right One)

If you’re actively looking for Folderly alternatives, you’re dealing with deliverability issues, warming up new domains, or trying to stay out of the spam folder.

We’ve heard this from dozens of cold emailers, founders, and SDRs. Folderly looks great at first. But over time, many users face the same issues.

But here’s the reality I’ve observed:

• It’s expensive, especially when you scale.
• You’ll still need other tools for outreach.
• Results aren’t always consistent or fast.
• Setting up the system requires effort, especially for non-technical users.
• And sometimes, bugs in automation can hurt your sender reputation.

That’s why I’ve put together a list of better Folderly alternatives. This list includes tools that are better (of course, than Folderly) when it comes to cost, ease of use, and functionality.

Let’s get started.

TL;DR of the 3 Best Folderly Alternatives to Improve Your Email Deliverability

1. Inbox Radar by Saleshandy – best for cold emailers, agencies

If you send cold emails and want to track inbox placement, sender reputation, and domain health without overspending, Inbox Radar is the tool to try.

2. GlockApps – best for pre‑send testing

Test your email content before sending. GlockApps reveals what might trigger spam filters so you can fix issues in advance.

3. MailMonitor – best for teams managing multiple domains

Ideal for agencies or sales teams working across several domains. MailMonitor delivers real‑time alerts on spam traps, blocklists, and inbox placement problems.

How I Chose These Folderly Alternatives (And Why It Matters to You)

I didn’t just look at what each tool claims to offer. I personally tested these platforms to see how they work in real situations.

Here’s what I looked for in each one:

• Can it help emails land in the inbox and avoid spam?
• Does it support sender reputation and warmup?
• Is it easy to use for cold emailers or marketers?
• Is the pricing fair for what it offers?
• What do real users say on G2, Capterra, and Reddit?

This helped me understand what each tool is really good at. So you can pick the right one for your email deliverability needs, without wasting time or money.

1. Inbox Radar by Saleshandy

Inbox Radar is a deliverability testing tool built inside Saleshandy. 

It helps you find out where your emails are landing and gives you the insights to fix issues before they affect your cold outreach.

How Inbox Radar Helps You Stay Out of Spam

You can run real placement tests across Gmail, Outlook, Yahoo, Zoho, and more. It supports manual, recurring, and external tests depending on how you send emails.

Spam scores are displayed using SpamAssassin with color indicators, allowing you to instantly assess the risk.

It also checks for DNS, blacklists, SPF, DKIM, and DMARC, giving a wholesome view of your domain health.

What makes it even better? Inbox Radar is already connected to your Saleshandy account. You don’t have to run tests separately. 

You can see real-time inbox placement and spam health, and adjust your campaigns on the go.

What Makes Inbox Radar the Best Alternative to Folderly?

Folderly offers recurring tests, but Inbox Radar gives you the same, at a much lower cost.

You also get a simpler interface and smoother navigation, making it easier for anyone to use without a learning curve.

The test reports are fast to generate, easy to share, and built for teams who need clear answers, quickly.

And it’s priced way better. You pay less and still get better control and insights.

Pricing

Starts at $23 per month for 15 inbox tests. It is flexible, transparent, and affordable than Folderly’s rigid $64 monthly plan.

2. GlockApps

GlockApps is a deliverability tool to run in-depth inbox placement insights and spam issue detection.

With GlockApps, you can check where your emails land (inbox, spam, or promotions) across different providers. 

Additionally, you can also review other aspects, such as content, technical, and reputation issues, that may be impacting your deliverability.

How GlockApps Helps You Stay Out of Spam

GlockApps test your email campaigns by sending them to a wide network of real test inboxes (including Gmail, Outlook, Yahoo, and more). 

So, you get to know where your emails are landing: in the inbox, spam, or other folders. It goes beyond simple warmup tools and highlights what’s affecting your inbox placement. 

That includes issues with content, blacklists, domain settings, and reputation.

You also get a SpamAssassin score, sender IP reputation analysis, and authentication checkups for SPF, DKIM, and DMARC. 

All these features help you find and resolve problems before you start your email campaign.

However, GlockApps doesn’t offer automatic warmup like some tools. It’s more useful for email testing and diagnostics than automation.

Why GlockApps Is a Good Folderly Alternative

If you want complete control over deliverability testing and better diagnostics, GlockApps can be the perfect replacement for Folderly.

With GlockApps, you get: 

• Detailed inbox placement reports
• Content checks
• Technical feedback 

All these points help you identify what’s wrong and improve your chances of hitting the inbox.

It’s especially helpful if you already know the basics and want detailed insights. 

Apart from that, it comes with flexible pricing for one-time or ongoing tests so that you can choose as per your requirement.

Pricing

GlockApps offers flexible pricing. You can run one-time tests starting at $16 or choose a monthly plan for ongoing testing needs.

Their basic plan starts at $59/month and includes unlimited testing, spam diagnostics, and full domain reputation tracking.

3. MailReach

MailReach is an email deliverability tool to improve your sender reputation, avoid the spam folder, and get better inbox placement (without having to manage things manually).

How MailReach Helps You Stay Out of Spam

The platform runs inbox placement tests using real inboxes from Gmail, Outlook, Yahoo, and other providers. That means you see where your emails actually land.

Plus, MailReach allows you to run fully automated warmup tests in the background. 

It sends emails, gets replies, and even moves emails out of spam folders to help build trust with email providers.

MailReach even helps to check your domain health, spam score, and email authentication setup (SPF, DKIM, DMARC). 

So if something’s hurting your deliverability, you’ll know and can fix it quickly.

The tool doesn’t go into detail about email content analysis like SpamAssassin, but it gives a clear picture of your overall deliverability health.

Why MailReach Is a Good Folderly Alternative

If you’re looking for an affordable and simple alternative to Folderly, MailReach is worth checking out.

It runs inbox warmups and deliverability tests, unlike tools that use AI simulations. You also get better pricing, which is approximately 8 times cheaper than Folderly per inbox.

MailReach requires minimal manual effort. You set it up once, and it continues to run in the background. For a team managing multiple campaigns, that’s a huge time-saving feature.

However, if you want customization or detailed reporting, MailReach may be limited. The only reason for this is that it’s built for simplicity rather than in-depth testing.

Pricing

MailReach pricing starts at around $25/month per inbox. That includes inbox placement tracking, domain health checks, 20 spam test credits, and full warmup features.

Compared to Folderly’s $96+/month per inbox, MailReach is a budget-friendly option, especially for growing teams or solo cold emailers.

4. InboxAlly

InboxAlly is a deliverability tool that helps your emails reach the inbox by simulating real human engagement.

It repairs sender reputation and maintains strong deliverability without manual tests or seed lists.

How InboxAlly Helps You Stay Out of Spam

I use InboxAlly to mimic real people. It opens, replies to, and interacts with my emails. These actions tell Gmail, Outlook, and Yahoo that my messages are safe.

That moves them out of spam and into the inbox. InboxAlly also shows where each test email lands—­inbox, spam, or promotions. So, I can track these results over time with clear reports. 

I don’t have to send to seed lists or run manual tests; InboxAlly handles everything in the background.

The tool also checks my SPF, DKIM, and DMARC records, but its main job is creating that human‑style engagement that keeps my deliverability strong.

Why InboxAlly Is a Good Folderly Alternative

If your emails are already landing in spam and nothing else has worked, InboxAlly offers a different approach than Folderly. 

Overall, InboxAlly changes how inbox providers see you through human-like interaction. Plus, you don’t have to configure complex testing flows or manage anything manually. 

It also runs automatically and starts improving inbox placement over time without much input from your side.

That said, it’s more expensive than many tools and doesn’t offer spam filter analysis. But if engagement is the problem, it can be the quickest path to recovery.

Pricing

InboxAlly plans start at $149/month for one sending address. The higher plans are available for teams managing volume or multiple inboxes.

5. MailGenius

MailGenius is a free tool that checks if your email is likely to land in the inbox or get flagged as spam. 

MailGenius scans your message for red flags and provides a clear spam score to identify and resolve issues that impact inbox placement.

How MailGenius Helps You Avoid Spam Traps

You send your email to a MailGenius test address. The tool scans your content, email headers, and authentication setup.

It checks your SPF, DKIM, and DMARC records to ensure proper configuration. It flags common deliverability issues like broken links, spam trigger words, and missing headers.

You get a simple score with clear suggestions to fix problems. This makes it easy to optimize your email before sending it to your actual prospects.

Although it doesn’t offer inbox placement testing like GlockApps or Mailreach, MailGenius still gives a reliable pre-send check to avoid basic mistakes that could send your email to spam.

Why MailGenius Is a Good Folderly Alternative

If you’re just starting out or looking for a spam checker, MailGenius is a great free alternative to Folderly.

It doesn’t rely on AI or warm-up features, but it’s quick and easy to use. 

The best part: You get quick feedback to resolve issues without any kind of complicated dashboard or setup.

Pricing

MailGenius is completely free. 

6. UnSpam

Unspam is an AI-based email deliverability tool that quickly checks if emails will reach the inbox or be sent to spam.

With UnSpam, you get insights into: 

• Real-time inbox placement testing
• Spam content checks
• Subject line grading
• Heatmap previews

All these features are available with a simple web interface.

How Unspam Helps You Stay Out of Spam

Unspam lets you test your emails across Gmail, Outlook, and Yahoo by sending to a real seed inbox network. 

You immediately see where your message lands, primary inbox, promotions, or spam.

Each test checks your content against spam filters and highlights risky keywords, broken links, formatting problems, or compliance issues. 

Plus, you get a clear spam score and a list of recommended changes.

Not only that, your subject line is graded based on spam trigger words and clarity. This way, you know if it’s hurting your deliverability before you hit send.

Unspam also checks SPF, DKIM, DMARC, reverse DNS, and blacklists. You get step-by-step instructions if anything is misconfigured.

For me, a standout feature is an AI-powered heatmap that shows which parts of your email attract attention. 

You also see how your message renders across devices and clients to prevent layout or design issues.

Why Unspam Is a Good Folderly Alternative

Unspam gives you accurate, instant feedback on inbox placement and spam risk at a fraction of Folderly’s cost.

You don’t need to install anything or connect it to your sending platform. Instead, you can just run a test from your browser. (That’s hassle-free and quick!)

If you’re looking to test, diagnose, and improve your cold emails without paying enterprise rates, Unspam is a strong alternative.

Pricing

Unspam offers a generous free plan with limited tests, while paid plans start at just $9/month for more inbox checks, spam tests, and heatmap previews. You can review its other plans to select the one that best suits your requirements.

7. Everest by Validity

Everest by Validity is a powerful deliverability platform that provides end-to-end visibility into inbox placement, sender reputation, and engagement metrics.

It combines technologies from Return Path, 250ok, and BriteVerify. (Pretty impressive!)

You gain advanced insights into authentication, blacklist checks, content health, and inbox outcomes.

How Everest Helps You Stay Out of Spam

Everest sends your email campaigns to a global seed list of inboxes (covering 100+ providers). This way, you exactly know where your emails land, primary, spam folder, or promotion tabs.

You receive detailed breakdowns by provider, device, and message type, enabling you to troubleshoot and adjust with precision.

Additionally, it monitors blacklists, spam traps, sender reputation (such as Sender Score), and feedback loops, and provides alerts if anything threatens your inbox rates. 

What else? You can see how your domain reputation and technical setup impact performance, before it’s too late.

The platform audits SPF, DKIM, DMARC, and reverse DNS in real time, and integrates with Google Postmaster and Microsoft SNDS for advanced visibility.

I personally like Everest because it goes further by offering insights into: 

• Content previews across devices
• Spam filter checks
• Heatmaps to show how people interact with your email
• Competitor benchmarking
• Engagement analytics to provide you with a 360° view of performance

Why Everest Is a Good Folderly Alternative

If you’re running large-scale email programs, Everest is the ideal alternative to Folderly.

As said, it offers far more diagnostic depth, like inbox placement by ISP, real-time alerts, design previews, and competitive tracking.

While it’s more expensive than basic tools and requires setup, the insights and protections it provides are unmatched. 

Everest is most beneficial to brands, especially where email deliverability is crucial.

That said, it may not be ideal for small senders or cold emailers seeking simple warm-up automation.

Pricing

Entry plans start from $20/month for smaller send volumes. Advanced features and agency-level insights are available in plans starting at $100/month and above.

8. Mailgun

Mailgun is a powerful email delivery service for technical teams to send, test, and track emails at scale. 

It helps improve inbox placement with tools like pre-send testing, domain reputation control, and automated warm-up.

How Mailgun Helps You Stay Out of Spam

Mailgun helps improve inbox placement through its “Optimize” feature, which lets you run inbox placement tests before sending a real campaign. 

You’ll see if emails land in inbox, promotions, or spam for Gmail, Yahoo, Outlook, and others, so that you can fix issues early.

It also monitors your domain and IP reputation. Regardless of whether you’re using a dedicated IP, Mailgun will automatically warm it up for you. 

Whether on shared or dedicated IPs, reputation is tracked and protected to help maintain good delivery rates.

Mailgun checks your email authentication via SPF, DKIM, and DMARC records. 

These checks are validated to identify technical issues and against best practices from ESPs.

Plus, you’ll also get real-time reports on bounce rates, spam complaints, and delivery issues, along with alerts when anything goes wrong.

What else? It’s built-in email list verification tool helps clean invalid emails, reduce hard bounces, and avoid spam traps.

All of these features work together to maintain a healthy sender reputation and improve inbox delivery rates over time.

Why Mailgun Is a Good Folderly Alternative

Mailgun is a strong Folderly alternative if you want full control over your sending setup and need inbox placement testing.

It’s more flexible for custom workflows and cold email integration, providing you with the tools to monitor, test, and protect your reputation.

While it doesn’t offer built-in outreach campaigns or automatic engagement simulations, its API, infrastructure monitoring, and deliverability tools are trusted by startups and large brands alike.

Pricing

Mailgun has a free plan for sending up to 100 emails/day. Paid plans with inbox testing and deliverability features start from around $35/month.

9. MailMonitor

MailMonitor is a deliverability platform that tracks exactly where their emails land, in the inbox, spam folder, or promotions folder. 

Additionally, it provides alerts about sender reputation, blocklists, and authentication issues.

If you ask me about MailMonitor, I’d say it’s made for businesses that want more control and visibility over how their emails perform, before hitting “send.”

How MailMonitor Helps You Stay Out of Spam

MailMonitor uses a massive seed list of over 400 inboxes across Gmail, Outlook, Yahoo, and other ISPs to determine your email deliverability. 

It continuously monitors your sending domain and IP address against major blocklists and reputation databases. 

In any case, if you get blacklisted or your sender score decreases, you’ll be alerted right away, allowing you to address the issue promptly.

Not only this, every test checks your authentication setup (SPF, DKIM, DMARC) and other technical settings.

Basically, to help you know if something is misconfigured or missing, you’ll know immediately, which helps you meet sending rules from Gmail and others.

Your email content is also scored for spam risks and compliance. If your copy might trigger spam filters, MailMonitor provides suggestions to help you adjust it before sending.

With MailMonitor, you get detailed reports on 

• Showing inbox placement
• Engagement data
• Technical diagnostics

These reports are helpful if you work with clients, teams, or want to share campaign results.

MailMonitor also offers API access so that you can connect it to your own systems or CRM for automated testing and alerts.

Why MailMonitor Is a Good Folderly Alternative

If you’re looking for a tool that offers inbox monitoring with reputation tracking and technical alerts, MailMonitor can be a strong alternative to Folderly.

It helps you find issues with content, IPs, or setup before they damage your deliverability. 

In my opinion, it’s especially helpful for agencies or growing teams that manage multiple domains or campaigns.

But if you’re looking for a tool with automatic warmup or simulated engagement, MailMonitor doesn’t include those features by default.

Pricing

MailMonitor starts at $49/month with inbox monitoring, spam scoring, and blacklist alerts. For more details, you can visit its pricing plan page.

It also automatically checks my SPF, DKIM, and DMARC setups and flags any issues, allowing me to fix them before going live.

Apart from that, MailTrap even checks your email headers and other technical details.

This is especially helpful now, as inbox providers like Gmail have become stricter about proper authentication.

Plus, you’ll get a spam score and content check for each message. What it includes: 

• Finding broken links

• Risky formatting
• Spam-triggering language

All this information is provided, along with suggestions on how to resolve the identified issues. 

There’s also an email preview feature, so you can see how your email will look across devices, platforms, and clients like Gmail mobile, Outlook desktop, and more.

It provides basic placement results, spam content checks, and authentication feedback at no cost or for a low fee. No logins, no integrations, no technical setup.

That said, it’s not built for automation, warmup, or sender reputation recovery. It works best as a pre-campaign check, not an ongoing deliverability solution.
