How this service works
Plus-address detection for Email operations: 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 the parsed email components indicating whether plus-addressing was detected in the local part, along with the base mailbox (the portion before the plus sign), derived from DNS data without sending email or verifying inbox existence.
Example use cases
Detect alias abuse at signup
“A user just signed up with 'alice+promo42@example.com' — can you check if that's a plus-addressed alias and tell me the real base mailbox so I can catch duplicate registrations?”
Normalize email before CRM storage
“Before I save this email 'support+ticket123@mycompany.com' to our CRM, can you strip out the plus-address tag and give me just the base mailbox?”
Flag sub-addressing in fraud review
“I'm reviewing a suspicious account that registered with 'bob+bypass@gmail.com' — can you detect whether that email uses sub-addressing and what the underlying address is?”

Use this endpoint when you need to detect and parse email sub-addressing (plus-addressing) to normalize user-submitted email addresses, catch duplicate registrations using alias tricks, or enrich identity data — especially when you only need DNS-level parsing without sending email or verifying inbox delivery.
Side effects
- Invalid or malformed email address input returns an error
- Email without a plus-address returns a negative detection result with the original address as base
- DNS lookup failures may cause timeouts or incomplete results
- Non-standard email formats may not be parsed correctly
