Monitor Your Sender Reputation

Everyone in the email game talks about maintain list quality and subscription issues but there are some more direct things you can do to keep an eye on your email reputation, and even with the strictest adherence to best practices, there is always a chance that a glitch or malicious act could negatively affect your reputation without you even noticing it.

You should make a point of checking established blocklists (also known as blacklists) on a regular basis. While ISPs don’t rely on blocklists as heavily as they once did, you should make sure your domains and IP addresses aren’t listed on the key blocklists that are still used by some ISPs and spam filtering providers. The following are some of the blocklists that have maintained popularity because of the integrity of their listing and delisting policies.
