Complaints

What is the meaning of Complaints?

When a recipient marks an email as “spam” after receiving it in their mail client, the sender gets an automatic message notifying them that a recipient sees their mail as spam. The total number of such feedback messages is called complaints. It is an email-centric metric that can adversely affect your sender reputation.
