Email Validation

What is the difference between Valid, Invalid, Unknown or Catch-All terms in the report?
Every email is primarily categorized as either Valid, Invalid, Unknown or Catch-All.
  Valid - After a successful SMTP transaction, if receiving mail server accepts the email address, it will be marked Valid Email Address. Sending emails to the addresses which are marked as "Disposable" is not recommended, even though the email address is valid.
  Invalid - An email address will be marked Invalid if it is syntactically incorrect or an email account does not exist on receiving mail server.
  Unknown - Sometimes receiving mail server responds very slowly or may temporarily be unable to process requests.
  Catch-All - An email address that accepts all mails for that email address and never bounces it back to the sender.
How can I identify the email addresses that are safe to send?
Clearout performs advance level filtering on valid email addresses to filter out false positive and risky emails. This process identifies good quality email addresses to achieve the best deliverability and increases your email open rates. These good quality addresses are marked as valid with a deliverability scoring greater than 0.75. We strongly recommend using email addresses that meet above conditions while sending emails in bulk.
How should you interpret or use the scoring results?
Every address you verify will have a deliverability score (DS). Higher the deliverability score then the email engagement will be higher with lower the bounce rate.

Understand the DS value results for your email list:

DS: 1 is a highly deliverable mail address that will hit the inbox.
DS: 0.75 is a low-risk email address (domain blacklisted)
DS: 0.5 is a medium risk email address (domain blacklisted)
DS: 0.25 is a high-risk email address (domain blacklisted)

Even though the address is valid, the chances of hitting the user inbox may change based on the deliverability score.
Does an email address marked "Deliverable" have no chance of bouncing?
Depends on the freshness of the validated result, we can guarantee that more than 98 % of "deliverable" email addresses won't bounce
What does the "Unknown" status mean?
The "Unknown" status means both the possibilities exist: the email may be valid or invalid. This happens when the receiving server is not responding well. We recommend you to retry such emails after some time.
What does the “Catch-All status” mean?
Sometimes receiving mail servers are configured such that it accepts all emails sent to them. This can be usually seen in business email addresses. In many cases, the receiving server accepts all emails for that domain and never bounces it back to the sender. We do not recommend to send emails to “Catch-All" addresses or send it slowly with caution. Deliverability for such addresses is not guaranteed.
What does the “Disposable Email” status mean?
There are certain service providers that generate temporary email addresses for a short period of time, like a few hours to a few days. Such addresses are known as "Disposable Email Addresses". Generally, disposable emails are created to receive initial account activation or confirmation emails for sites like discussion forums, e-shopping etc. and dispose off automatically after a given time period. Sending emails to such addresses increases the bounce rate so it is not advisable to send emails to "Disposable Email Addresses".
What does the “Role Account Email” status mean ?
Role-based email addresses are such emails that do not belong to individuals, but to a department, designation or company. The owner of Role-based addresses often changes. Further, the email may be forwarded to multiple recipients. Sending newsletters or campaign emails to such addresses may have a negative impact on your open rates or may lead to spam complaints. Hence, it is not recommended to send any promotional or marketing emails to Role addresses. Most email marketing services reject such role addresses.
What does the “Free Account Email” status mean?
Clearout detects if the email address is registered with one of the popular free email services, e.g. Google, AOL, Hotmail, Yahoo etc. This is important, because such addresses are typically personal email addresses, instead of work email addresses. Such addresses are safe to send emails to, but in many cases, engagement opportunities are higher with work email addresses than with personal email addresses.
What does the “Autosuggestion” status mean?
Every incorrectly typed email address is a missed opportunity for marketers to connect with their customers and prospects. Clearout has an in-built autosuggestion feature which checks in real-time, if there is a typo. The autosuggestion will provide an alternative spelling which is more likely to be the correct email address.
For example, if a user types the email address as "[email protected]", the corrected spelling "[email protected]" will be suggested.
Is there any risk that the user IPs and domains get blacklisted by using Clearout service?
All processing is done on Clearout servers, the user IP addresses and domains are not affected in any way by the Clearout service - absolutely no blacklisting risk for the IPs and domains.
Does Clearout send any email to do the validation?
No, it doesn't. Clearout employs DNS and SMTP protocol functionalities to perform email address validations and absolutely avoids sending any email message to external mail exchangers for delivery.
What is the Maximum bulk validation queue limit?
Our email verification tool allows a maximum of 3 requests per user at a time in queue, whether it is in queued state or running

Verification Analytics

What does the “Performance Stats” mean?
Business critical KPIs can be effectively achieved with our detailed performance stats based on the verification. This is how we calculate the performance stats:
Total Verified = Total no of emails - no of emails categorized ‘unknown’
Bounce Detection Rate = (no of invalid emails / (no of valid and invalid emails)) * 100
Estimated Cost Saved is the heuristic way of determining cost incurred for sending emails without our validation, this involves multiple factors to find the actual cost saved.
