The Master Invalid List has been added to prevent bounces and help your reputation as a sender. Sending emails to invalid email addresses or sending continuously to the same invalid email address might cause damage to your reputation as a sender. Benchmark Email understands the importance of maintaining our client’s sending reputation. Therefore we introduced features like Reputation Health Score to monitor the health of your database and now the Master Invalid List.
After you’ve sent an email campaign, an Invalid Email List is created by our system and added to your account. The list is compiled with the recipient’s email addresses that were marked by an ISP as invalid emails. The Master Invalid List will only show up in the Contact List Dashboard if and when you send a campaign that contains invalid emails.
The contacts added to the Invalid List are filtered from all future mailings and list uploads. This provides you better options to manage the Invalid Email addresses and also ensures that they are not added back to a List in the future.
If you think that an email address was wrongly added as Invalid or the issue due to which it was marked as an Invalid email address (like issues with the Domains DNS settings) has been fixed. You may remove the individual email address from the list and add it back to your regular lists.
Once an email address has been removed from the Master Invalid List and added back to an active contact list, the system will send them emails again.
