When you upload email lists older than 6 months, it is good to have database cleaning for the list before sending email campaigns.
Database cleaning is a tool you can use to improve your delivery rates. The result of database cleaning is a good quality list of active email addresses. You can use third-party services to do that or we can clear up your lists of unwanted, inactive (hard bounces) contacts, before importing them into the Mailigen platform. Because we're sure, you don't want to damage the reputation of your domain, this is a highly suggested procedure.
