How this service works
Email address normalization for Security review: Normalize case and identify a plus-address tag without sending mail. DNS data only; does not send email or verify that an inbox exists.
Output
Returns the normalized (case-folded) form of the email address and identifies any plus-address tag present in the local part, based on DNS data only. No email is sent and no inbox existence is verified.
Example use cases
Fraud detection on signup email
“A user just signed up with the email 'JohnDoe+promo123@Gmail.COM' — can you normalize it and check if it's using a plus-address trick so I can flag potential duplicate accounts?”
Security audit of collected emails
“I need to inspect the email 'admin+alerts@MyCompany.ORG' to normalize its casing and extract any subaddress tag for our security review — no emails should be sent.”
Deduplication before CRM import
“Before I import contacts, can you normalize 'Sales.Lead+CRM@outlook.com' and tell me the canonical address and plus tag so I can deduplicate entries properly?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-email-normalize-security-review?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to canonicalize email addresses and detect plus-address subaddressing for security, fraud detection, or deduplication purposes without triggering any mail delivery or requiring inbox verification. Prefer this over full email verification services when you only need structural normalization and tag extraction with no side effects.
Side effects
- Malformed email address input returns a validation error
- Email domain not resolvable via DNS may limit domain-level normalization
- No plus tag present returns an empty or null tag field
- Non-standard email formats (e.g. quoted local parts) may not parse as expected
