Bulk Email Verifier is able to verify whether an email address is valid or not. An email address is considered
as valid if a message sent to this email address will be delivered. Although this does not guarantee that the
message will be read by a real person, it is a good way to filter an email list before trying to send a message.
Bulk Email Verifier does not send any emails to target email addresses, it only verifies whether sending is
possible. Owners of target email addresses thus are unaware that an email verification check was done. The
verification is done using a combination of DNS and SMTP protocol techniques. DNS queries are used to find
responsible mail servers for each email address. The SMTP protocol is then used to verify that at least one of
the responsible mail servers will accept an email for the given email address.
Bulk Email Verifier is very rich in its features and abilities to provide accurate and extensive information
about verified emails. It supports greylisting, which
allows it to verify email addresses on many more mail servers than common email verification tools. Our tool also
runs from a server with a correctly configured SPF record and a valid reverse DNS record. This guarantees that the
tool provides most accurate results possible and its requests are not refused by target mail servers. Moreover,
Bulk Email Verifier checks whether catch-all address is configured for each email domain and its analysis can thus
provide extra useful information to the end user. Finally, the tool recognizes hundreds of disposable and 10 minute
email services and alerts the user in case an email from such a service is detected.
Fill in the Email(s) field with email addresses you want to be checked. Use one email address
per line. Then hit the Check emails! button.
If you are familiar with greylisting, you can set the Greylisting delay value to specify how
long should the tool wait before the second attempt to verify an email address is made after greylisting was
detected. If you set this value to Disabled then the Email Verifier tool will not
attempt to verify emails for the second time when greylisting is detected. The higher the Greylisting delay
value, the longer the tool can operate and the more accurate the results will be.
Note that each non-empty line is considered as an email address, but if you enter a string that can not be an
email address, no credits will be charged for that line.
For each valid email address, Bulk Email Verifier provides a detailed analysis that can be displayed using the
View details link in the output table. The details are availabled even during the verification process
before the actual result is known. You can thus check the progress of the verification process before it
finishes.
API for Bulk Email Verifier is available in
