Verification Results Codes explained

Home Knowledge Base Email Verification Verification Results Codes explained

Our email verification feature can return a few different text codes that helps you determine if an email is valid and safe to send. Attached below is a short table that will help you understand our results.

Text Code Description Safe to send?
Valid Verified email address. Yes
Invalid Un-verified email address. No
Risky Server is set to Catch-All but we’ve managed to find at least one data source that can validate the email. Maybe
CatchAll Server is set to Catch-All. Maybe
Unknown Non-existing mail server or no response. No
Not Found When none of our datasets has found a result No




What is Catch All

This is also known as an “accept all”. This is a domain-wide setting where all emails on this domain will be reported as a catch-all. There is no definitive way to determine whether this email is valid or invalid.

A catch-all address is commonly used in small businesses to ensure a company receives any email that has been sent to them, regardless of typos. Oftentimes these are in-fact valid emails. However some organisations may utilise this setting as a security feature to prevent unsolicited emails.

How Risky is different from Catch All?

Risky means that the while the recipient’s mail server is set to Catch-All, we managed to find at least one data source that claim to validate the existence of the email. Even though we couldn’t give a certain answer about the address validity, there are good odds that the email indeed exists.
