Safeguard and boost your email security by detecting domain blocklisting!
An email DNS blacklist, also known as a DNSBL or RBL, is a database of IP addresses and domains associated with spam and phishing activities. Email servers use these blacklists to identify and block suspicious emails.
Organizations collect data on spam and phishing activities, including IP addresses, domains, and email addresses. When an email server receives an email, it checks the sender's information against blacklists. If a match is found, the email may be rejected, quarantined, or marked as spam.
An email DNS blacklist checker tool is a software program that checks an email address or domain against a database of known spammers and phishing websites. If a match is found, the email will be flagged as spam and potentially blocked from reaching your inbox.
