Verifying Email addresses with our API

2. Email deliverability Guarantee
Email deliverability is the foundation for a successful email marketing program. If you’re not getting emails delivered, you don’t have a proper email marketing program. We at Clearout understand the importance of email deliverability and that's why we adopt best practices for email verification to offer our customers the best possible accuracy in the industry. We back up our verification results with a 97% deliverability rate guarantee. In other words, when you verify your email addresses with Clearout, we guarantee that the bounce rate will not be more than 3% in case of messages sent to “Guaranteed Deliverable” email addresses or the flag Safe-to-Send set as "Yes".
In order to qualify for our guarantee, the following criterias must be met-
- Email addresses must be classified as the guaranteed deliverable
- The email is sent anytime before 24 hours from the verified time
- Email addresses must have been acquired by the Opt-in process only. Email addresses acquired by purchased or rented lists are not covered under this guarantee.
- Free service providers such as Yahoo, AOL will not be covered
- Bounces resulting from technical issues, sender reputation being poor, recipient server reaching maximum receiving capacity, mail server being improperly configured, server not being available, or the recipient has specifically banned the sender's email identity, delivery blocked due to internal rules, etc. won't qualify for this guarantee.
3. Understanding Clearout Results
Safe to Send
The safe-to-send flag is based on best practices followed in the industry, At times there can be a situation when even a valid email bounces back. There can be multiple reasons for the same, that's why we have introduced the safe to send feature. It provides the below-mentioned 4 values which determine how secure an email address is based on the probability of bounce-back
| Yes | Sending emails to these email addresses is completely safe as long as the email is sent anytime before 24 hours from the verified time. |
| Risky | As the name suggests, a little risk is involved in sending emails to these email addresses but the email addresses of this result file are safe to use when the bounce rate is strictly below 5% or using own email sending platform without depending on external Email Service Provider (ESP). The risk factor depends upon multiple reasons like -High volume of role-based email addresses -Any temporary mail account issue -Mail server configured to accept all email messages |
| No | Invalid email addresses that you should avoid sending emails to. |
| Unknown | Due to unavoidable reasons, the status of the email cannot be determined currently |
Status
The status gives a broad picture of the quality of the email addresses. After successful email verification, every email address is primarily categorized as either Valid, Invalid, Catch-All or Unknown.
| Valid | A valid email address has been verified as a real email that is currently accepting the emails |
| Invalid | An invalid email address has been verified as a bad recipient address that does not exist or is not accepting the emails. Invalid emails will result in a bounce |
| Catch-all | Certain servers accept all the emails for that domain and never bounces it back to the sender, those email addresses are flagged as catchall emails. |
| Unknown | 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. |
Status Reasons
Apart from the email verification results mentioned above, the report generated will contain the status reasons for the given status results. The definition of each status reason is explained below.
| Status Reason | Description | Clearout Status | Bounce Type |
|---|---|---|---|
| Success | This email address is valid and safe to send emails. | Valid | |
| Failure | This email address belongs to a mail server that is returning a temporary error | Unknown | |
| Syntax error | This email address is a commonly misspelled popular domain according to RFC standards. | Invalid | Hard |
| Probably Spamtrap/Honeypot | These email addresses are believed to be spamtraps, must avoid sending mails. | Invalid | Soft |
| Mail server connection timeout | Unable to connect to mail server with in stipulated time, recommend to retry some time later | Unknown | |
| Domain not found | This email address is valid in syntax, but the domain doesn't have any records in DNS or have incomplete DNS Records. | Invalid | Hard |
| Not a Mail Server | This email address doesn’t belong to a mail server. | Invalid | Hard |
| Mail server error | This email address belongs to a mail server that is returning a temporary error. | Unknown | |
| Mailbox not found | This email address is valid in syntax but does not exist. | Invalid | Hard |
| Mail server employed greylisting technique; so try after sometime | Domain IP of the specified email address is greylisted, advice to retry some time later | Unknown | |
| Catch-All mail server | Mail server has been configured to receive all messages that are addressed to an incorrect email address for a domain | Catch-All | |
| Unable to determine; retry later after an hour or so | This email address is not responding at the particular moment so you can retry later an hour or so. | Unknown | |
| Mailbox quota exceeded | This email address exceeded the space quota and are not accepting any emails. | Invalid | Soft |
| Retry later after an hour or contact support | The server didnot allow verification of the emails, temporarily. As we do not charge for the unknowns it is always advisible to retry verifying at a later point of time. | Unknown | |
| No Answer Received From Authoritative Server | This email address belongs to a mail server that is not responding at the time of verification. | Unknown | |
| Dns Query Timeout | Unable to resolve DNS with in stipulated time, so retry at a later time increasing the timeout parameter(API verification) | Unknown | |
| Dns Query Unhandled Error | This email address belongs to a mail server that is returning a temporary error. | Unknown | |

Associated Results
Here are the other result related terms to help you get a better understanding
| Score | Providing the score is based on multiple factors is a unique feature of Clearout. Each email address is assigned a score value range from 0-1 to indicate the probability of email message getting delivered to that email address. The overall score at list level is an average score of all valid email addresses in percentage form
| |||||||||||||||
| Disposable Email Address | 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". | |||||||||||||||
| Free Email Address | 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. | |||||||||||||||
| Role Based Email Address | 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 | |||||||||||||||
| Greylist Count | 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". | |||||||||||||||
| Auto suggestion | 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] | |||||||||||||||
| Verification Timestamp | Clearout provides the verified time for every email address to ensure the freshness of your list. | |||||||||||||||
| Verification Time Taken | Clearout provides the response time taken for every email address by a simple open relay check. |
