Every email address you verify will have a clear and transparent result to understand the verification status. Here’s what each terminology used in your email verification report:

After the successful email verification, every email address is primarily categorized as either Valid, Invalid , Catch-All or Unknown.

A valid email address has been verified as a real email that is currently accepting mail.

Clearout will return an unknown result when it was unable to get a response from the recipient's mail server. This often happens if the destination mail server is too slow or temporarily unavailable due to an issue with their internal network or expired domain names. In certain cases, retrying your request after some time will return a valid or invalid response.

Clearout provides a delivery score for every address after the successful email verification to determine the address is safe to send emails or not. Higher the delivery scores then the email engagement will be higher with lower the bounce rate.

Understand the delivery score for every email address in your list:

Clearout provides the greylist count for every address after the successful email verification to check whether the email address is a honeypot or not. Sending emails to addresses with a higher greylist count will increase the bounce rate so it is highly recommended not to send emails to "Greylisted Email Addresses".

Clearout checks if the email address belongs to a temporary account created for a short period of time, like a few hours to a few days. Generally, disposable emails are created to receive initial account activation or confirmation emails for sites like discussion forums, e-shopping etc. Sending emails to such addresses increases the bounce rate so it is highly recommended not to send emails to "Disposable Email Addresses".

Clearout identifies the email addresses that are using free services such as Gmail and Yahoo! Mail. In many cases, it is perfectly acceptable to send email to a user of a free email service. However, in certain contexts, businesses can receive better open/response rates when only sending to non-free email addresses.

Clearout identifies the email addresses that are typically associated with a role (postmaster, support, sales, etc.) instead of a person. In some instances, mailing to a role address can lead to a decreased open rate and is generally advised against while sending an email.

Clearout provides autosuggestion feature which checks in real-time if there is a typo. The autosuggestion will pose an alternative email address when Clearout notices a potentially mistyped address. For instance, if a user types the email address as "[email protected]", Clearout will suggest the corrected spelling [email protected]

Clearout provides the verified time for every email address to ensure the freshness of your list.
