Overview

Clean your marketing or sales lists by checking if emails are correctly formatted, from a valid domain, or from a disposable service. Essential for improving deliverability and protecting your sender score.

An email list is only valuable if the messages actually get delivered. High bounce rates not only waste your time and budget but also damage your domain's sending reputation, making it harder to reach the inbox in the future. This tool acts as a pre-flight check for your email campaigns. It runs three critical checks on every email address you provide: ### Validation Checks * **Format Check:** Ensures the email follows the standard `user@domain.com` syntax. This catches basic typos and formatting errors. * **DNS Check:** Verifies that the email's domain is real and has the necessary mail server records (MX records) to receive email. This weeds out addresses from non-existent domains. * **Disposable Email Check:** Identifies emails from known temporary or throwaway services. These are often used for one-time sign-ups and are useless for building a long-term relationship. By scrubbing your list of these problematic addresses, you ensure your campaigns are sent to real, valid inboxes. This leads to better open rates, more accurate campaign data, and a healthier sender reputation with providers like Gmail and Outlook.
