How to verify emails in bulk
If we want to verify a large mailing lists of email addresses, the most effective and simple way is to use a file.
We must place the email addresses in files, one below the other. The email addresses must share the same column.
Once we have published the file all we have to do is select the column where the email addresses are and wait for the verification process to finish. Depending on the number of emails to be validated, the process can take from seconds to hours. By patient, that will reduce your overall bounce rate. At the end of the process you will receive an email address to the email account you used to register, notifying you of the completion of the process.
