Frequently Asked Questions
What is an email blacklist?
An email blacklist, or DNSBL, is a reputation list that receiving servers can use to block mail from IP addresses associated with spam, abuse, or compromised infrastructure.
Does one blacklist listing mean all email is blocked?
No. Mailbox providers combine many signals, including authentication, complaint rates, engagement, and sender history. A listing is still a strong signal that needs investigation.
How do I get removed from a blacklist?
Fix the cause first: compromised accounts, open relays, bad sending lists, or misconfigured infrastructure. Then follow the delisting process published by the specific blacklist operator.
