Why IP/Domain Blacklisting Matters
Email servers check blacklists before accepting mail. If your sending IP or domain is listed, your emails may be rejected or sent to spam. Regular monitoring helps maintain good deliverability and protect your sender reputation.
Common Causes of Blacklisting
- Sending to purchased email lists
- High complaint rates from recipients
- Compromised email accounts sending spam
- Open relay configurations on mail servers
- Shared hosting with other blacklisted senders
