What's a spam checker?

A spam checker is an tool designed to help people measure their deliverability and inbox placement and make improvements if something is wrong.
When you send emails, making sure to reach the inbox is crucial. That's why it's important to regularly measure your deliverability and check where your emails land to make sure your recipient receive them in inbox.
A proper spam checker helps you test your deliverability, see what your email lands on the major inbox providers and give you practical guidelines to improve your inbox placement.

What is our spam test tool checking?

First, our email spam test tool checks your inbox placement : where your email lands on Google, Microsoft and Yahoo mailboxes.
On top of that, it will also check your content for spam words, blacklisted domains, insecure or broken links, attachments, images, tracking pixels, HTML code, etc.
Lastly, MailReach's spam test tool will check your setup: DNS records such as your SPF, DKIM, DMARC and MX records. It will also analyze your reverse DNS, domain age and check if your domain or mail server IP are blacklisted.

What do I do with the email spam test results?

With the email spam test results, there are many things you can do.
First, you can share the email spam test report to anyone that might be interested to see it. It can be useful if you can’t make the changes recommended by MailReach and you need someone to do it for you.
Depending on the results you get from the email spam test, several scenarios can happen :
Best scenario : the email spam test gives you a 10/10 which means a perfect deliverability. That’s great. Make sure you have all the green lights in the “Checks” and “Setup” sections.
Second scenario : You have a lower score but all the lights are green. In that case, it can be a sending reputation problem AND/OR spam words that can’t be detected by MailReach AND/OR you sending tool (sending IP, tracking domain, etc.)
What you can do is running a new email spam test with a normal / casual email inviting someone for a call (two sentences max), without using any sending tool, to see if you get a better score.
Third scenario : the email spam test gives a lower score and MailReach gives you things you can improve. In that case, make the changes and run the email spam test again until you see improvements.

How to get a 10/10 email spam test score?

Having 10/10 on our email spam test means having a perfect deliverability with the email and setup you’ve tested.
First, you need to know that in some cases, you just can’t hit an email spam test score of 10/10 because of the type of emails you send. It does not mean you can’t have a perfect deliverability towards the inboxes you target with your email campaigns. Today, you can land 100% in the inbox on professional inboxes (Office 365, Google Workspace) and at the same time land in spam on personal inboxes such as Outlook.com, Gmail.com, Hotmail.com.
Why? Because they don’t filter spam the same way AND the big providers can mark as spam the fact you send business emails to a private inbox which is not supposed to happen.
In all cases, if you have an email spam test score below 10/10, the best things you can do to improve your score are:
  • Make changes to your email and/or sending setup until the email spam test gives you a higher score.
  • Raise your sending reputation with email warming if needed until you get a better email spam test score.

Is our spam checker completely free ?

Our Email Spam Checker is free for up to 3 tests per 24 hours. If you need to perform more tests, then you'll be invited to purchase spam test credits or subscribe to a monthly plan.

I send emails from different countries, do I have to do an email spam test several times?

Sending emails from different countries doesn’t mean you need to do several email spam tests.
Doing an email spam test several times is very useful to iterate and try to improve your spam score. But it’s not related to sending emails from different countries.
An email spam test should be done each time you change your email content (wording, links, images) and/or way of sending your emails (campaign sending tool, tracking domain, sending IP, domain, email address, etc).

Are the emails stored?

MailReach needs to store the emails to be able to make your deliverability reports available.

Is our free spam checker tool safe ?

Our free spam checker is 100% safe. There's no risk for you except landing in spam on our test which means your deliverability is damaged.
But that's what you want to check right? :)
Our spam checker doesn't harm your sender reputation nor your deliverability. It's simply a way to measure your inbox placement and see what you can improve.

What are spam test credits?

When buying a paid plan, spam test credits are used for inbox placement tests.
1 spam test credit = 1 inbox placement test with an associated deliverability report.
To put it simply, if you have 100 spam test credits, you can run 100 separate inbox placement tests and receive a deliverability report for each one.
