Emails being marked as spam can have a devastating impact on a business's engagement and revenue. It's a problem that needs to be addressed as soon as possible. When emails are marked as spam, it leads to a domino effect, with the IP reputation being lowered, negatively impacting email deliverability. As a result, most emails will get filtered out by the receiver's ISP, and won't even make it to the inbox.

While there are various ways to lessen spam rates, it can be challenging to determine which approach works best for a particular domain. However, with Google Postmaster you can get accurate data on your domain’s spam rate, and then take proactive measures to reduce it.
