Risky emails are addresses that may cause deliverability issues when included in your campaigns. Catch-all (also known as accept-all) addresses belong to domains configured to receive all incoming messages, regardless of whether a specific mailbox actually exists.
This means any email sent to the domain — even to random or misspelled addresses — will be accepted by the server. Standard email verification tools can detect these domains but cannot determine which individual addresses are actually valid.
Common types of risky emails include:
- Catch-all/Accept-all addresses: Server accepts everything
- Temporary or disposable emails: Created for short-term use
- Spam trap addresses: Used by ISPs to identify spammers
- Role-based addresses: Generic addresses like info@, admin@, support@
Scrubby specializes in validating these risky emails through deep inbox-level testing, giving you definitive valid/invalid results instead of uncertain "risky" classifications.
