My Experience With The 5 Best Inbox Placement Tools in 2025

I signed up and tested multiple tools to see how each one performed.

The main thing I looked for was how many email service providers (ESPs) you can test against, like Gmail, Outlook, Yahoo, and others.

These are the 5 tools that made it to my list:

1. Inbox Radar by Saleshandy
2. GlockApps
3. MailReach
4. Folderly
5. MxToolbox

1. Inbox Radar by Saleshandy

The best inbox placement tool I used in 2025 is Inbox Radar by Saleshandy.

Of all the platforms I tested, this one gave me the clearest picture of where my emails were actually landing.

Inbox Radar’s seed list has the following ESPs:

• Gmail
• Outlook
• Google Workspace
• Microsoft O365
• Zoho
• Yahoo

The results came in quickly and were super easy to understand.

Moreover, Inbox Radar gives you extra insights on your email and domain health, authentication records setup, blacklist status, and even a spam score by SpamAssassin.

The most useful was the ESP-to-ESP Placements Report.

It shows a side-by-side breakdown of where your emails landed with each service provider, giving you an idea of which ESPs are flagging your emails and which ones are letting them through to the inbox.

There are three different ways you can run inbox placement tests in Inbox Radar:

1. Manual (One-Time Test): Send a single email to check where it lands.
2. Automated (Recurring Test): Set up regular, automated tests to keep track of your deliverability over time.
3. External Test: Use an external email account or service to check how your emails perform outside your usual setup.

This gives you the flexibility to test as often as you want and keep a close eye on your sender reputation.

Pricing (Billed Annually)

Inbox Radar has 2 paid plans:

1. Inbox Starter – $23/month (25 placement tests/month)
2. Inbox Pro – $79/month (Unlimited tests/month)

Saleshandy also has a free spam and inbox placement checker you can use to text things out.

2. GlockApps

If you’re looking for a very comprehensive inbox placement analysis from various ESPs across different countries, GlockApps is a tool you’ll want to consider.

Its seed list covers a wide range of ESPs, including:

• Amazon WorkMail
• Exchange (Office 365)
• Google Workspace (older and newer accounts)
• Protonmail
• Outlook
• Yahoo
• And many more

You’re not limited to just US-based mailboxes either. GlockApps lets you test your emails across multiple regions, such as:

• Europe
• CIS (Russia)
• Asia/Pacific (Korea)

It’s ideal if you send campaigns to international audiences.

The only downside? It works on a credit system, and the costs add up if you run a lot of tests.

GlockApps Pricing (Billed Annually)

GlockApps is actually pretty expensive. There are 3 credit packs

1. Credits Pack 1 – $16.99 (3 Credits)
2. Credits Pack 2 – $47.99 (10 Credits)
3. Credits Pack 3 – $75.99 (20 Credits)

3. MailReach

MailReach stands out because it combines inbox placement testing with automated email warm-up.

So if you want to not only check where your emails land but also improve your sender reputation at the same time, this is a handy option.

What I liked most is how beginner-friendly it feels. You don’t have to be a technical expert to follow their recommendations, and the whole setup is quick.

That said, the spam-testing part is priced reasonably, but if you go for the full combo, you’ll be charged per mailbox.

MailReach Pricing (Billed Annually)

MailReach uses a credit-based pricing model.

4. Folderly

If you’re looking for a modern, clean, and easy-to-use platform for inbox placement testing, Folderly is a strong pick.

After Saleshandy, Folderly is the only tool on this list that lets you run unlimited inbox placement tests on its paid plans.

Also, with Folderly, you get insights on your sender IPs, blacklist status, and DNS records, along with step-by-step guides to help you fix any deliverability issues that come up.

The only drawback is that Folderly’s seed list covers only Google and Outlook (personal and business accounts), which is quite limiting if you want to test deliverability for other providers.

Folderly Pricing

Folderly offers a free plan, plus one monthly and one yearly paid plan.

• The monthly plan is $79/month
• The annual plan works out to $64/month when billed yearly

5. MxToolbox

MxToolbox is more of an all-in-one email deliverability tool than a pure inbox placement tester.

You can:

• Check your domain’s blacklist status
• Monitor authentication records like SPF, DKIM, and DMARC
• Keep an eye on your overall sender reputation

Coming to the inbox placement part, similar to the other tools, you can send a test email to a seed list of addresses.

MxToolbox then shows you where your email is likely to land for providers like Gmail, Yahoo, and Outlook.com.

Where it falls short is on the interface—it’s a bit more technical, so it might take some getting used to.

MxToolbox Pricing

There is a free plan that you can use for blacklist monitoring.

MxRoolbox also has 2 paid plans:

1. Delivery Center – $129/month
2. Delivery Center Plus – $399/month
