MailboxValidator is an easy to use email address validation service. Users have an option to validate a single email address or do a bulk validation of a list of email addresses. Using an email address verifier service like MailboxValidator can help lower your email marketing campaign costs.
After you have performed email address verification, your email list will have less stale emails that will translate into less bounces.
The single email validation is pretty straightforward where the user signs in to our website and then selects Single Validation in the dashboard page. A text field will appear and all they have to do is key in the email address and press the Validate button. After a short while, the email validation results will be shown.
There is also an API if you want to integrate this form of validation into your programs. See our Single Validation API page for more info.
In the same dashboard page, there is another option called Bulk Validation. With this one, the user just has to select a file of email addresses and press the Upload & Process button. Depending on the number of emails to be validated, the validations may take a while. On average, a list of 500,000 emails will take about a day to complete the validation.
The bulk validation can take a text file of email addresses with an email address per line as below:
Alternatively, the user can also upload a CSV file with other data fields and our system will determine which field contains the email address as below:
When the bulk validation process is completed, an email will be sent to the user and they can just sign in to our system and view the results or download the results in the form of a CSV file.
One thing to note for the bulk validation is that there is a queue for all uploaded files. If the uploaded file does not seem to have any progress, this could be due to the fact that it is in the queue. Rest assured that the file will be processed in due time.
In the CSV result file, there are some fields with True or False values. Below are the meanings of those fields:
