Email blocklist is a list of email addresses or domains that are blocked from sending messages to recipients due to spam complaints, high bounce rates, or other issues. Being on a blocklist can significantly impact email deliverability.
If an email sender lands on a blocklist, their messages may be filtered out or rejected. For example, consistently sending bulk emails without proper permissions can trigger spam filters and result in blocklist placement.
Being on a blocklist damages email deliverability, reducing the chances of messages reaching inboxes. Marketers monitor their sending reputation and follow best practices like using clean email lists and avoiding spammy content. Regularly checking for blocklist status helps ensure emails reach their intended audience effectively.
