Millionverifier – Email Verification Results


Ok, Invalid, Catch all, Disposable, Unknown – Good, Bad, Risky

When you verify your emails using The Email List Company & MillionVerifier, we provide you with one of the following quality results for each email:

  1. Ok means the email address exists. Ok are good emails and are SAFE to send an email to.
  2. Invalid means the email address does not exist. Invalids are bad emails and are NOT SAFE to send an email to.
  3. Disposable means this email account is hosted on a temporary email address provider. Disposable emails may exist only for a few minutes. Therefore, they are bad emails. It is NOT SAFE to send an email to these addresses.
  4. Catch-All means the email server is set to accept all mail, even emails sent to an account that does not exist. So it can be RISKY to send an email to these addresses. Read more on catch-all here.
  5. Unknown means that we couldn’t determine whether the email address exists at the time of the verification. Possibly we can successfully verify unknowns at a later time. It can be RISKY to send an email to these addresses.


The accuracy of our results is virtually 100% at the time of the verification. However, verification results depend on the response we receive from the mail server of the domain.

For example, if we say an email is invalid, it means you would experience a hard bounce if you emailed them at the time of the verification. But the email may have existed before or even later on.

We invest a significant amount of time and money to keep improving our accuracy. We are proud of achieving a 99% accuracy that makes us the most accurate email verifier on the market.


Which emails can I use?

  • GOOD (Ok) emails are SAFE to use.
  • BAD (Invalid and Disposable) emails are NOT SAFE to use. These Have Been Deleted From Your List
  • RISKY (Catch-all and Unknown) emails may be safe to use if they are real subscribers and recently subscribed.

Catch-All Emails

What are catch-all emails?

Catch-all is a server setting. It means the server is set to accept all mail even if the email address doesn’t exist. 

Catch all server

For example, if Peter works at an HR company, his email address is peter@hrcompany.com. When Peter leaves the job, they will not continue using his email address anymore. However, they might want to see if a customer emails him. They disable his email address, and all mail going to his email address is forwarded to, e.g., info@hrcompany.com. So basically, if an email address doesn’t exist, the email is forwarded to a generic email address.

Why is a catch-all risky?

Some email servers that are set to catch-all send a bounce message when an email is sent to a non-existing email address. 

However, risky emails can be used, but only if:

  • they are real subscribers (not purchased list, nor collected from the internet)
  • they have subscribed recently (less than two months ago) 

You can read here which emails you can use.

Want to double-check the authenticity of catch-all emails?

Sending them an email is the most definitive approach. While MillionVerifier refrains from emailing your subscribers during the check, a service like Scrubby can step in for added assurance. Scrubby dispatches a silent blank email, helping you filter out any unreliable catch-all addresses, no matter their age or origin. Keep your email lists clean and efficient!

Free & Role Email

What are free and role emails? Besides verifying email addresses, we highlight which email addresses are role-based emails and which ones are hosted on free email services.

Free email accounts

“Free” indicates that the email address is registered with a free email service provider, e.g., Gmail, Hotmail, or Yahoo. 

Role email accounts

“Role” indicates that the email address is not directly related to a person but rather a role, e.g., sales, admin, or support. Using role emails for email marketing is not recommended as they are more likely to mark your emails as spam.

Good, Risky and Bad Emails

Which emails can I send emails to following the email verification?

You can use Ok emails and, in some cases, Risky emails (Unknown and Catch-all). For email marketing, it is also recommended to filter out role emails. 

Good Emails

Ok means the email address exists, and it is safe to send emails to. MillionVerifier offers a 100% money-back guarantee on Ok emails.  

Risky Emails

You can use risky emails only if:

  • they are real subscribers (not purchased list, nor collected from the internet)
  • they have subscribed recently (less than two months ago)

Risky emails fall into two categories: 

  • Unknown: This means that we couldn’t verify the email address at the time of the verification.
  • Catch all: This means the email server is set to accept all mail even if the email account doesn’t exist. 

You can try verifying the Unknown emails again later, and you might get the results of them, if the previous problem doesn’t occur, and we can verify the email addresses.


Unsure about ‘risky’ emails?

The best method to confirm their validity is to send them an email directly. MillionVerifier doesn’t contact your subscribers during verification. For a more in-depth check, consider using Scrubby. It sends a blank email to the addresses, helping you determine the actual status of these ‘risky’ emails, even if they were obtained long ago or sourced from the internet. Ensure your email list’s accuracy and effectiveness.

Bad Emails

Never use bad emails. Bad emails fall into two categories:

  • Invalid: This means the email account doesn’t exist.
  • Disposable: This means the email address is just a temporary email address.
