What Are Risky Emails?
After the email verification process, it can happen that you have a number of Risky emails in your results. Risky emails fall into two categories:
- They can be Unknown, meaning that we couldn’t define whether the email address truly existed at the time of the email verification. It is possible that we can successfully verify these email addresses later.
- Or, they can be Catch-all. Catch-all means that the server is set to accept all the emails, even if they are sent to a non-existent account. Basically, if an email address doesn't exist, the email is forwarded to a generic email address.
Some email servers that are set to catch-all send a bounce message when an email is sent to a non-existing email address.
How to Use Risky Emails?
In the case of all Risky emails, we advise you only to send emails to these addresses if:
- They are authentic subscribers, and not collected or purchased from the internet,
- They subscribed recently, preferably within the last 2 months.
In all other cases, if you don't want to through away risky emails, you must further verify them. The only way to tell whether they can be used or not is by sending an email to them. At MillionVerifier, we avoid sending emails to your subscribers. However, there is a service that sends a bank email to them to help you determine whether it is safe to use these.
