Identify email addresses known for marking emails as spam.
What are abuse emails?
Abuse emails are addresses associated with users who frequently:
- Mark emails as spam
- Submit abuse complaints
- Report emails to blacklist services
Risk factors
Sending to known complainers can:
- Trigger spam filters
- Damage your sender score
- Result in ISP blocks
- Get you listed on blacklists
Detection methods
Detection works from the address itself — Kawaa does not need any sending history from you. An address is checked against:
- Known abuse and complaint-handling local parts, such as abuse@, spam@ and complaints@
- Published feedback-loop (FBL) addresses operated by mailbox providers and reputation services
- Domains that exist specifically to receive complaints and abuse reports
- Naming patterns associated with serial complainers and legal-threat addresses
Addresses that are ambiguous — where an abuse@ mailbox may be a legitimate corporate contact rather than a complaint trap — are additionally classified for intent, so a real support address is not excluded by pattern alone.
API response
The result is the boolean data.flags.abuse_email, with data.flags.complainer set for high-confidence complaint addresses. Both count toward quality_score, but an address with either flag can still score in a range that looks safe, as in the example below. Check the flags themselves before you send, alongside status. There is no separate abuse score.
