How this service works
Plus-address detection for IT administration: Detect sub-addressing in an email local part and return the base mailbox. DNS data only; does not send email or verify that an inbox exists.
Output
Returns whether the input email uses plus-addressing (sub-addressing), the extracted sub-address tag if present, and the base mailbox (local part without the plus-tag combined with the domain). No email is sent and no inbox existence is verified — result is based on DNS data and address parsing only.
Example use cases
Block duplicate signups via plus-addresses
“A user just registered with 'john+test@gmail.com' — can you check if this is a plus-address trick and tell me the real base mailbox so I can flag potential duplicate accounts?”
Normalize email for CRM deduplication
“I have this email in our CRM: 'support+ticket42@company.org' — can you detect if it's sub-addressed and give me the canonical base mailbox to use for deduplication?”
IT audit of employee email aliases
“As part of our IT audit, check whether 'jane.doe+hr@ourcompany.com' is a plus-address variant and return the underlying base mailbox address.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-plus-address-check-it-administration?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically detect and strip plus-address tags from email inputs — particularly useful in IT administration, user registration deduplication, CRM normalization, or security auditing workflows. Prefer this over general email validation APIs when your specific need is sub-address detection rather than deliverability or syntax validation.
Side effects
- Invalid or malformed email address returns an error or null result
- Email without a plus-address returns a no-subaddress indicator
- Domain DNS lookup issues may affect result accuracy
- Non-standard or internationalized email formats may not be parsed correctly
