Email Blocklist

Definition

An Email Blocklist, also known as an Email Blacklist, is a database of IP addresses or domains that are suspected to send spam emails. Internet Service Providers (ISPs), Email Service Providers (ESPs), and third-party services often maintain these lists to protect email users from spam or malicious content. If an IP address or domain is on a blocklist, emails sent from that source are likely to be marked as spam or even rejected entirely.

Email blocklists are used widely across the internet to maintain email integrity and safety. They play a crucial role in the world of email marketing, where high deliverability rates are essential for success. If a business finds itself on an email blocklist, it can significantly impact their email marketing efforts, causing their emails to be blocked or sent directly to the recipient's spam folder.
