Understanding Email Verification Result
After successful email verification, a complete report explaining the status of each email will be generated. The generated report will be very transparent and easy to understand. The terminology used in your email verification report is explained below.
Verification Result
Every email is primarily categorized as either Valid, Invalid or Unknown.
-
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 "Accept All" or "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 many temporarily be unable to process requests. In this case, the email address will be marked Unknown and email verification won't be counted (This makes QuickEmailVerification different from other service providers). In most cases, such emails can be re-verified after 5 to 10 minutes. The results will show whether the email address is Valid or Invalid.
Results that have been marked Unknown are not deducted from your total credit.
Associated Reasons
Apart from the email verification results mentioned above, the report generated will contain the associated reasons for the given results. The reason string elaborates the email verification results by specifying more detailed reason behind the email result. For example, Invalid Email can be classified further as syntactically 'invalid_email' or as receiving server has 'no_mx_record' or 'rejected_email'. The definition of each reasons is explained below.
| Invalid_email | The syntax of the email address is invalid (Is not according to RFC standards). |
| Invalid_domain | The domain used in email address doesn't exist. |
| rejected_email | SMTP server rejected email. Email account doesn't exist on receiving server. |
| accepted_email | SMTP server accepted email. |
| no_connect | Could not connect to receiving SMTP server. |
| timeout | Session timeout occurred on remote SMTP server. It happens when the receiving mail server is responding too slow. |
| unavailable_smtp | Receiving SMTP server was not available to process a request. |
| unexpected_error | Some unexpected error has occurred on the receiving SMTP server. |
| no_mx_record | MX record of the domain doesn’t exist. |
| temporarily_blocked | Email address is temporary greylisted. |
| exceeded_storage | Email account on receiving server has exceeded storage allocation. |

Accept All
It is also called Catch-All email addresses. 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 of the domain and then simply discard the mail or bounce it back to sender. Such bounces can hurt the sender's IP reputation and reduce your deliverability so it is not recommended to send emails to "Accept All" addresses or send it slowly with caution. Deliverability for such addresses are not guaranteed.
Disposable Email Addresses
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 mails for sites like discussion forums, e-shopping etc and dispose automatically after given time period. Sending emails to such addresses increases the bounce rate so it is not advisable to send emails to "Disposable Email Addresses".
Role-based Email Addresses
Role-based email addresses are such emails that does 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 rejects such role addresses.
Free service email
QuickEmailVerification 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.
Did You Mean
Every incorrectly typed email address is a missed opportunity for businesses to connect with their customers and prospects. QuickEmailVerification's in-built auto-corrector checks, in real-time, if there is a typo. The Did You Mean suggestion will provide an alternative spelling which is more likely to be the correct email address. In such a case, the user should be asked to correct the entered email address. For example, if a user types her email address as "user@yaho.com", the corrected spelling "user@yahoo.com" will be suggested.
