Avoid Bad Email Reputation - Keep Your List Clean

A recent Return Path study shows that bad email sender reputation, and not content, is responsible in 83% of all cases where email does not reach the recipient.
Sending emails to invalid addresses damages your online reputation and ruins your business. Existing email address lists should be cleaned regularly from outdated or invalid email addresses to avoid getting blacklisted.
