Domain Reputation Evaluation: Assessing Your Online Standing

The tool works by checking the email against a list of known disposable email domains, which is continuously updated. It also tries to connect to the email server over SMTP and simulates sending an email to see if it is valid. It then reports if the email is an authenticated, valid or invalid email address.

If an email address is flagged as disposable, it may not receive follow-up emails from the marketer. This is because many of the top disposable email services routinely wipe accounts and remove their logs after a certain amount of time. These addresses are a nightmare for marketers and can cause them to spend a lot of time and money trying to capture and engage potential customers, only to find that their account is no longer valid, thus making them a waste of resources.

To protect your email list from disposable email addresses, you can sign up for a Kickbox account (free and open) or our Email Verify API service (with a 100 free test credit). Both services provide an official integration with Kickbox as well as an API endpoint that checks for disposable addresses in real-time.
